### ✨ Enhanced Features
|
||||
|
||||
**Workflow Mutation Telemetry for AI-Powered Workflow Assistance**
|
||||
|
||||
Added comprehensive telemetry tracking for workflow mutations to enable more context-aware and intelligent responses when users modify their n8n workflows. The AI can better understand user intent and provide more relevant suggestions.
|
||||
|
||||
#### Key Improvements
|
||||
|
||||
1. **Intent Parameter for Better Context**
|
||||
- Added `intent` parameter to `n8n_update_full_workflow` and `n8n_update_partial_workflow` tools
|
||||
- Captures user's goals and reasoning behind workflow changes
|
||||
- Example: "Add error handling for API failures" or "Migrate to new node versions"
|
||||
- Helps AI provide more relevant and context-aware responses
|
||||
|
||||
2. **Comprehensive Data Sanitization**
|
||||
- Multi-layer sanitization at workflow, node, and parameter levels
|
||||
- Removes credentials, API keys, tokens, and sensitive data
|
||||
- Redacts URLs with authentication, long tokens (32+ chars), OpenAI-style keys
|
||||
- Ensures telemetry data is safe while preserving structural patterns
|
||||
|
||||
3. **Improved Auto-Flush Performance**
|
||||
- Reduced mutation auto-flush threshold from 5 to 2 events
|
||||
- Provides faster feedback and reduces data loss risk
|
||||
- Balances database write efficiency with responsiveness
|
||||
|
||||
4. **Enhanced Mutation Tracking**
|
||||
- Tracks before/after workflow states with secure hashing
|
||||
- Captures intent classification, operation types, and change metrics
|
||||
- Records validation improvements (errors resolved/introduced)
|
||||
- Monitors success rates, errors, and operation duration
|
||||
|
||||
#### Technical Changes
|
||||
|
||||
**Modified Files:**
|
||||
- `src/telemetry/mutation-tracker.ts`: Added comprehensive sanitization methods
|
||||
- `src/telemetry/telemetry-manager.ts`: Reduced auto-flush threshold, improved error logging
|
||||
- `src/mcp/handlers-workflow-diff.ts`: Added telemetry tracking integration
|
||||
- `src/mcp/tool-docs/workflow_management/n8n-update-full-workflow.ts`: Added intent parameter documentation
|
||||
- `src/mcp/tool-docs/workflow_management/n8n-update-partial-workflow.ts`: Added intent parameter documentation
|
||||
|
||||
**New Test Files:**
|
||||
- `tests/unit/telemetry/mutation-tracker.test.ts`: 13 comprehensive sanitization tests
|
||||
- `tests/unit/telemetry/mutation-validator.test.ts`: 22 validation tests
|
||||
|
||||
**Test Coverage:**
|
||||
- Added 35 new unit tests for mutation tracking and validation
|
||||
- All 357 telemetry-related tests passing
|
||||
- Coverage includes sanitization, validation, intent classification, and auto-flush behavior
|
||||
|
||||
#### Impact
|
||||
|
||||
Users will experience more helpful and context-aware AI responses when working with workflows. The AI can better understand:
|
||||
- What changes the user is trying to make
|
||||
- Why certain operations succeed or fail
|
||||
- Common patterns and best practices
|
||||
- How to suggest relevant improvements
|
||||
|
||||
This feature is completely privacy-focused with comprehensive sanitization to protect sensitive data while capturing the structural patterns needed for better AI assistance.

# N8N-MCP Telemetry Database Analysis
|
||||
|
||||
**Analysis Date:** November 12, 2025
|
||||
**Analyst Role:** Telemetry Data Analyst
|
||||
**Project:** n8n-mcp
|
||||
|
||||
## Executive Summary
|
||||
|
||||
The n8n-mcp project has a comprehensive telemetry system that tracks:
|
||||
- **Tool usage patterns** (which tools are used, success rates, performance)
|
||||
- **Workflow creation and validation** (workflow structure, complexity, node types)
|
||||
- **User sessions and engagement** (startup metrics, session data)
|
||||
- **Error patterns** (error types, affected tools, categorization)
|
||||
- **Performance metrics** (operation duration, tool sequences, latency)
|
||||
|
||||
**Current Infrastructure:**
|
||||
- **Backend:** Supabase PostgreSQL (hardcoded: `ydyufsohxdfpopqbubwk.supabase.co`)
|
||||
- **Tables:** 2 main event tables + workflow metadata
|
||||
- **Event Tracking:** SDK-based with batch processing (5s flush interval)
|
||||
- **Privacy:** PII sanitization, no user credentials or sensitive data stored
|
||||
|
||||

|
||||
|
||||
## 1. Schema Analysis
|
||||
|
||||
### 1.1 Current Table Structures
|
||||
|
||||
#### `telemetry_events` (Primary Event Table)
|
||||
**Purpose:** Tracks all discrete user interactions and system events
|
||||
|
||||
```sql
|
||||
-- Inferred structure based on batch processor (telemetry_events table)
|
||||
-- Columns inferred from TelemetryEvent interface:
|
||||
-- - id: UUID (primary key, auto-generated)
|
||||
-- - user_id: TEXT (anonymized user identifier)
|
||||
-- - event: TEXT (event type name)
|
||||
-- - properties: JSONB (flexible event-specific data)
|
||||
-- - created_at: TIMESTAMP (server-side timestamp)
|
||||
```
|
||||
|
||||
**Data Model:**
|
||||
```typescript
|
||||
interface TelemetryEvent {
|
||||
user_id: string; // Anonymized user ID
|
||||
event: string; // Event type (see section 1.2)
|
||||
properties: Record<string, any>; // Event-specific metadata
|
||||
created_at?: string; // ISO 8601 timestamp
|
||||
}
|
||||
```
|
||||
|
||||
**Rows Estimate:** 276K+ events (based on prompt description)
|
||||
|
||||
---
|
||||
|
||||
#### `telemetry_workflows` (Workflow Metadata Table)
|
||||
**Purpose:** Stores workflow structure analysis and complexity metrics
|
||||
|
||||
```sql
|
||||
-- Structure inferred from WorkflowTelemetry interface:
|
||||
-- - id: UUID (primary key)
|
||||
-- - user_id: TEXT
|
||||
-- - workflow_hash: TEXT (UNIQUE, SHA-256 hash of normalized workflow)
|
||||
-- - node_count: INTEGER
|
||||
-- - node_types: TEXT[] (PostgreSQL array or JSON)
|
||||
-- - has_trigger: BOOLEAN
|
||||
-- - has_webhook: BOOLEAN
|
||||
-- - complexity: TEXT CHECK IN ('simple', 'medium', 'complex')
|
||||
-- - sanitized_workflow: JSONB (stripped workflow for pattern analysis)
|
||||
-- - created_at: TIMESTAMP DEFAULT NOW()
|
||||
```
|
||||
|
||||
**Data Model:**
|
||||
```typescript
|
||||
interface WorkflowTelemetry {
|
||||
user_id: string;
|
||||
workflow_hash: string; // SHA-256 hash, unique constraint
|
||||
node_count: number;
|
||||
node_types: string[]; // e.g., ["n8n-nodes-base.httpRequest", ...]
|
||||
has_trigger: boolean;
|
||||
has_webhook: boolean;
|
||||
complexity: 'simple' | 'medium' | 'complex';
|
||||
sanitized_workflow: {
|
||||
nodes: any[];
|
||||
connections: any;
|
||||
};
|
||||
created_at?: string;
|
||||
}
|
||||
```
|
||||
|
||||
**Rows Estimate:** 6.5K+ unique workflows (based on prompt description)
|
||||
|
||||
---
|
||||
|
||||
### 1.2 Local SQLite Database (n8n-mcp Internal)
|
||||
|
||||
The project maintains a **SQLite database** (`src/database/schema.sql`) for:
|
||||
- Node metadata (525 nodes, 263 AI-tool-capable)
|
||||
- Workflow templates (pre-built examples)
|
||||
- Node versions (versioning support)
|
||||
- Property tracking (for configuration analysis)
|
||||
|
||||
**Note:** This is **separate from Supabase telemetry** - it's the knowledge base, not the analytics store.
|
||||
|
||||
---
|
||||
|
||||
## 2. Event Distribution Analysis
|
||||
|
||||
### 2.1 Tracked Event Types
|
||||
|
||||
Based on source code analysis (`event-tracker.ts`):
|
||||
|
||||
| Event Type | Purpose | Frequency | Properties |
|
||||
|---|---|---|---|
|
||||
| **tool_used** | Tool execution | High | `tool`, `success`, `duration` |
|
||||
| **workflow_created** | Workflow creation | Medium | `nodeCount`, `nodeTypes`, `complexity`, `hasTrigger`, `hasWebhook` |
|
||||
| **workflow_validation_failed** | Validation errors | Low-Medium | `nodeCount` |
|
||||
| **error_occurred** | System errors | Variable | `errorType`, `context`, `tool`, `error`, `mcpMode`, `platform` |
|
||||
| **session_start** | User session begin | Per-session | `version`, `platform`, `arch`, `nodeVersion`, `isDocker`, `cloudPlatform`, `startupDurationMs` |
|
||||
| **startup_completed** | Server initialization success | Per-startup | `version` |
|
||||
| **startup_error** | Initialization failures | Rare | `checkpoint`, `errorMessage`, `checkpointsPassed`, `startupDuration` |
|
||||
| **search_query** | Search operations | Medium | `query`, `resultsFound`, `searchType`, `hasResults`, `isZeroResults` |
|
||||
| **validation_details** | Configuration validation | Medium | `nodeType`, `errorType`, `errorCategory`, `details` |
|
||||
| **tool_sequence** | Tool usage patterns | High | `previousTool`, `currentTool`, `timeDelta`, `isSlowTransition`, `sequence` |
|
||||
| **node_configuration** | Node setup patterns | Medium | `nodeType`, `propertiesSet`, `usedDefaults`, `complexity` |
|
||||
| **performance_metric** | Operation latency | Medium | `operation`, `duration`, `isSlow`, `isVerySlow`, `metadata` |
|
||||
|
||||
**Estimated Distribution (inferred from code):**
|
||||
- 40-50%: `tool_used` (high-frequency tracking)
|
||||
- 20-30%: `tool_sequence` (dependency tracking)
|
||||
- 10-15%: `error_occurred` (error monitoring)
|
||||
- 5-10%: `validation_details` (validation insights)
|
||||
- 5-10%: `performance_metric` (performance analysis)
|
||||
- 5-10%: Other events (search, workflow, session)
|
||||
|
||||

|
||||
|
||||
## 3. Workflow Operations Analysis
|
||||
|
||||
### 3.1 Current Workflow Tracking
|
||||
|
||||
**Workflows ARE tracked** but with **limited mutation data:**
|
||||
|
||||
```typescript
|
||||
// Current: Basic workflow creation event
|
||||
{
|
||||
event: 'workflow_created',
|
||||
properties: {
|
||||
nodeCount: 5,
|
||||
nodeTypes: ['n8n-nodes-base.httpRequest', ...],
|
||||
complexity: 'medium',
|
||||
hasTrigger: true,
|
||||
hasWebhook: false
|
||||
}
|
||||
}
|
||||
|
||||
// Current: Full workflow snapshot stored separately
|
||||
{
|
||||
workflow_hash: 'sha256hash...',
|
||||
node_count: 5,
|
||||
node_types: [...],
|
||||
sanitized_workflow: {
|
||||
nodes: [{ type, name, position }, ...],
|
||||
connections: { ... }
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Missing Data for Workflow Mutations:**
|
||||
- No "before" state tracking
|
||||
- No "after" state tracking
|
||||
- No change instructions/transformation descriptions
|
||||
- No diff/delta operations recorded
|
||||
- No workflow modification event types
|
||||
|
||||

## 5. Missing Data for N8N-Fixer Dataset
|
||||
|
||||
### 5.1 Critical Gaps for Workflow Mutation Tracking
|
||||
|
||||
To support the n8n-fixer dataset requirement (before workflow → instruction → after workflow), the following data is **currently missing:**
|
||||
|
||||
#### Gap 1: No Mutation Events
|
||||
```
|
||||
MISSING: Events specifically for workflow modifications
|
||||
- No "workflow_modified" event type
|
||||
- No "workflow_patch_applied" event type
|
||||
- No "workflow_instruction_executed" event type
|
||||
```
|
||||
|
||||
#### Gap 2: No Before/After Snapshots
|
||||
```
|
||||
MISSING: Complete workflow states before and after changes
|
||||
Current: Only stores sanitized_workflow (minimal structure)
|
||||
Needed: Full workflow JSON including:
|
||||
- Complete node configurations
|
||||
- All node properties
|
||||
- Expression formulas
|
||||
- Credentials references
|
||||
- Settings
|
||||
- Metadata
|
||||
```
|
||||
|
||||
#### Gap 3: No Instruction Data
|
||||
```
|
||||
MISSING: The transformation instructions/prompts
|
||||
- No field to store the "before" instruction
|
||||
- No field for the AI-generated fix/modification instruction
|
||||
- No field for the "after" state expectation
|
||||
```
|
||||
|
||||
#### Gap 4: No Diff/Delta Recording
|
||||
```
|
||||
MISSING: Specific changes made
|
||||
- No operation logs (which nodes changed, how)
|
||||
- No property-level diffs
|
||||
- No connection modifications tracking
|
||||
- No validation state transitions
|
||||
```
|
||||
|
||||
#### Gap 5: No Workflow Mutation Success Metrics
|
||||
```
|
||||
MISSING: Outcome tracking
|
||||
- No "mutation_success" or "mutation_failed" event
|
||||
- No validation result before/after comparison
|
||||
- No user satisfaction feedback
|
||||
- No error rate for auto-fixed workflows
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 5.2 Proposed Schema Additions
|
||||
|
||||
To support n8n-fixer dataset collection, add:
|
||||
|
||||
#### New Table: `workflow_mutations`
|
||||
```sql
|
||||
CREATE TABLE IF NOT EXISTS workflow_mutations (
|
||||
id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
|
||||
user_id TEXT NOT NULL,
|
||||
workflow_id TEXT NOT NULL, -- n8n workflow ID (optional if new)
|
||||
|
||||
-- Before state
|
||||
before_workflow_json JSONB NOT NULL, -- Complete workflow before mutation
|
||||
before_workflow_hash TEXT NOT NULL, -- SHA-256 of before state
|
||||
before_validation_status TEXT, -- 'valid', 'invalid', 'unknown'
|
||||
before_error_summary TEXT, -- Comma-separated error types
|
||||
|
||||
-- Mutation details
|
||||
instruction TEXT, -- AI instruction or user prompt
|
||||
instruction_type TEXT CHECK(instruction_type IN (
|
||||
'ai_generated',
|
||||
'user_provided',
|
||||
'auto_fix',
|
||||
'validation_correction'
|
||||
)),
|
||||
mutation_source TEXT, -- Tool/agent that created instruction
|
||||
|
||||
-- After state
|
||||
after_workflow_json JSONB NOT NULL, -- Complete workflow after mutation
|
||||
after_workflow_hash TEXT NOT NULL, -- SHA-256 of after state
|
||||
after_validation_status TEXT, -- 'valid', 'invalid', 'unknown'
|
||||
after_error_summary TEXT, -- Errors remaining after fix
|
||||
|
||||
-- Mutation metadata
|
||||
nodes_modified TEXT[], -- Array of modified node IDs
|
||||
connections_modified BOOLEAN, -- Were connections changed?
|
||||
properties_modified TEXT[], -- Property paths that changed
|
||||
num_changes INTEGER, -- Total number of changes
|
||||
complexity_before TEXT, -- 'simple', 'medium', 'complex'
|
||||
complexity_after TEXT,
|
||||
|
||||
-- Outcome tracking
|
||||
mutation_success BOOLEAN, -- Did it achieve desired state?
|
||||
validation_improved BOOLEAN, -- Fewer errors after?
|
||||
user_approved BOOLEAN, -- User accepted the change?
|
||||
|
||||
created_at TIMESTAMP DEFAULT NOW()
|
||||
);
|
||||
|
||||
CREATE INDEX idx_mutations_user_id ON workflow_mutations(user_id);
|
||||
CREATE INDEX idx_mutations_workflow_id ON workflow_mutations(workflow_id);
|
||||
CREATE INDEX idx_mutations_created_at ON workflow_mutations(created_at);
|
||||
CREATE INDEX idx_mutations_success ON workflow_mutations(mutation_success);
|
||||
```
|
||||
|
||||
#### New Event Type: `workflow_mutation`
|
||||
```typescript
|
||||
interface WorkflowMutationEvent extends TelemetryEvent {
|
||||
event: 'workflow_mutation';
|
||||
properties: {
|
||||
workflowId: string;
|
||||
beforeHash: string;
|
||||
afterHash: string;

### 6.2 Privacy & Sanitization
|
||||
|
||||
The system implements **multi-layer sanitization:**
|
||||
|
||||
```typescript
|
||||
// Layer 1: Error Message Sanitization
|
||||
sanitizeErrorMessage(errorMessage: string)
|
||||
├─ Removes sensitive patterns (emails, keys, URLs)
|
||||
├─ Prevents regex DoS attacks
|
||||
└─ Truncates to 500 chars
|
||||
|
||||
// Layer 2: Context Sanitization
|
||||
sanitizeContext(context: string)
|
||||
├─ [EMAIL] → email addresses
|
||||
├─ [KEY] → API keys (32+ char sequences)
|
||||
├─ [URL] → URLs
|
||||
└─ Truncates to 100 chars
|
||||
|
||||
// Layer 3: Workflow Sanitization
|
||||
WorkflowSanitizer.sanitizeWorkflow(workflow)
|
||||
├─ Removes credentials
|
||||
├─ Removes sensitive properties
|
||||
├─ Strips full node configurations
|
||||
├─ Keeps only: type, name, position, input/output counts
|
||||
└─ Generates SHA-256 hash for deduplication
|
||||
```
|
||||
|
||||

|
||||
|
||||
## 7. Recommendations for N8N-Fixer Dataset Implementation
|
||||
|
||||
### 7.1 Immediate Actions (Phase 1)
|
||||
|
||||
**1. Add Workflow Mutation Table**
|
||||
```sql
|
||||
-- Create workflow_mutations table (see Section 5.2)
|
||||
-- Add indexes for user_id, workflow_id, created_at
|
||||
-- Add unique constraint on (user_id, workflow_id, created_at)
|
||||
```
|
||||
|
||||
**2. Extend TelemetryEvent Types**
|
||||
```typescript
|
||||
// In telemetry-types.ts
|
||||
export interface WorkflowMutationEvent extends TelemetryEvent {
|
||||
event: 'workflow_mutation';
|
||||
properties: {
|
||||
// See Section 5.2 for full interface
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**3. Add Tracking Method to EventTracker**
|
||||
```typescript
|
||||
// In event-tracker.ts
|
||||
trackWorkflowMutation(
|
||||
beforeWorkflow: any,
|
||||
instruction: string,
|
||||
afterWorkflow: any,
|
||||
instructionType: 'ai_generated' | 'user_provided' | 'auto_fix',
|
||||
success: boolean
|
||||
): void
|
||||
```
|
||||
|
||||
**4. Add Flushing Logic to BatchProcessor**
|
||||
```typescript
|
||||
// In batch-processor.ts
|
||||
private async flushWorkflowMutations(
|
||||
mutations: WorkflowMutation[]
|
||||
): Promise<boolean>
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 7.2 Integration Points
|
||||
|
||||
**Where to Capture Mutations:**
|
||||
|
||||
1. **AI Workflow Validation** (n8n_validate_workflow tool)
|
||||
- Before: Original workflow
|
||||
- Instruction: Validation errors + fix suggestion
|
||||
- After: Corrected workflow
|
||||
- Type: `auto_fix`
|
||||
|
||||
2. **Workflow Auto-Fix** (n8n_autofix_workflow tool)
|
||||
- Before: Broken workflow
|
||||
- Instruction: "Fix common validation errors"
|
||||
- After: Fixed workflow
|
||||
- Type: `auto_fix`
|
||||
|
||||
3. **Partial Workflow Updates** (n8n_update_partial_workflow tool)
|
||||
- Before: Current workflow
|
||||
- Instruction: Diff operations to apply
|
||||
- After: Updated workflow
|
||||
- Type: `user_provided` or `ai_generated`
|
||||
|
||||
4. **Manual User Edits** (if tracking enabled)
|
||||
- Before: User's workflow state
|
||||
- Instruction: User action/prompt
|
||||
- After: User's modified state
|
||||
- Type: `user_provided`
|
||||
|
||||
---
|
||||
|
||||
### 7.3 Data Quality Considerations
|
||||
|
||||
**When collecting mutation data:**
|
||||
|
||||
| Consideration | Recommendation |
|
||||
|---|---|
|
||||
| **Full Workflow Size** | Store compressed (gzip) for large workflows |
|
||||
| **Sensitive Data** | Still sanitize credentials, even in mutations |
|
||||
| **Hash Verification** | Use SHA-256 to verify data integrity |
|
||||
| **Validation State** | Capture error types before/after (not details) |
|
||||
| **Performance** | Compress mutations before storage if >500KB |
|
||||
| **Deduplication** | Skip identical before/after pairs |
|
||||
| **User Consent** | Ensure opt-in telemetry flag covers mutations |
|
||||
|
||||
---
|
||||
|
||||
### 7.4 Analysis Queries (Once Data Collected)
|
||||
|
||||
**Example queries for n8n-fixer dataset analysis:**
|
||||
|
||||
```sql
|
||||
-- 1. Mutation success rate by instruction type
|
||||
SELECT
|
||||
instruction_type,
|
||||
COUNT(*) as total_mutations,
|
||||
COUNT(*) FILTER (WHERE mutation_success = true) as successful,
|
||||
ROUND(100.0 * COUNT(*) FILTER (WHERE mutation_success = true)
|
||||
/ COUNT(*), 2) as success_rate
|
||||
FROM workflow_mutations
|
||||
WHERE created_at >= NOW() - INTERVAL '30 days'
|
||||
GROUP BY instruction_type
|
||||
ORDER BY success_rate DESC;
|
||||
|
||||
-- 2. Most common workflow modifications
|
||||
SELECT
|
||||
nodes_modified,
|
||||
COUNT(*) as frequency
|
||||
FROM workflow_mutations
|
||||
WHERE created_at >= NOW() - INTERVAL '30 days'
|
||||
GROUP BY nodes_modified
|
||||
ORDER BY frequency DESC
|
||||
LIMIT 20;
|
||||
|
||||
-- 3. Validation improvement distribution
|
||||
SELECT
|
||||
(errors_before - COALESCE(errors_after, 0)) as errors_fixed,
|
||||
COUNT(*) as count
|
||||
FROM workflow_mutations
|
||||
WHERE created_at >= NOW() - INTERVAL '30 days'
|
||||
AND validation_improved = true
|
||||
GROUP BY errors_fixed
|
||||
ORDER BY count DESC;
|
||||
|
||||
-- 4. Before/after complexity transitions
|
||||
SELECT
|
||||
complexity_before,
|
||||
complexity_after,
|
||||
COUNT(*) as count
|
||||
FROM workflow_mutations
|
||||
WHERE created_at >= NOW() - INTERVAL '30 days'
|
||||
GROUP BY complexity_before, complexity_after
|
||||
ORDER BY count DESC;
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 8. Technical Implementation Details
|
||||
|
||||
### 8.1 Current Event Queue Configuration
|
||||
|
||||
```typescript
|
||||
// From TELEMETRY_CONFIG in telemetry-types.ts
|
||||
BATCH_FLUSH_INTERVAL: 5000, // 5 seconds
|
||||
EVENT_QUEUE_THRESHOLD: 10, // Queue 10 events before flush
|
||||
MAX_QUEUE_SIZE: 1000, // Max 1000 events in queue
|
||||
MAX_BATCH_SIZE: 50, // Max 50 per batch
|
||||
MAX_RETRIES: 3, // Retry failed sends 3x
|
||||
RATE_LIMIT_WINDOW: 60000, // 1 minute window
|
||||
RATE_LIMIT_MAX_EVENTS: 100, // Max 100 events/min
|
||||
```
|
||||
|
||||
### 8.2 User Identification
|
||||
|
||||
- **Anonymous User ID:** Generated via TelemetryConfigManager
|
||||
- **No Personal Data:** No email, name, or identifying information
|
||||
- **Privacy-First:** User can disable telemetry via environment variable
|
||||
- **Env Override:** `TELEMETRY_DISABLED=true` disables all tracking
|
||||
|
||||
### 8.3 Error Handling & Resilience
|
||||
|
||||
```
|
||||
Circuit Breaker Pattern:
|
||||
├─ Open: Stop sending for 1 minute after repeated failures
|
||||
├─ Half-Open: Resume sending with caution
|
||||
└─ Closed: Normal operation
|
||||
|
||||
Dead Letter Queue:
|
||||
├─ Stores failed events temporarily
|
||||
├─ Retries on next healthy flush
|
||||
└─ Max 100 items (overflow discarded)
|
||||
|
||||
Rate Limiting:
|
||||
├─ 100 events per minute per window
|
||||
├─ Tools and Workflows exempt from limits
|
||||
└─ Prevents overwhelming the backend
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 9. Conclusion
|
||||
|
||||
### Current State
|
||||
The n8n-mcp telemetry system is **production-ready** with:
|
||||
- 276K+ events tracked
|
||||
- 6.5K+ unique workflows recorded
|
||||
- Multi-layer privacy protection
|
||||
- Robust batching and error handling
|
||||
|
||||
### Missing for N8N-Fixer Dataset
|
||||
To build a high-quality "before/instruction/after" dataset:
|
||||
1. **New table** for workflow mutations
|
||||
2. **New event type** for mutation tracking
|
||||
3. **Full workflow storage** (not sanitized)
|
||||
4. **Instruction preservation** (capture user prompt/AI suggestion)
|
||||
5. **Outcome metrics** (success/validation improvement)
|
||||
|
||||
### Next Steps
|
||||
1. Create `workflow_mutations` table in Supabase (Phase 1)
|
||||
2. Add tracking methods to TelemetryManager (Phase 1)
|
||||
3. Instrument workflow modification tools (Phase 2)
|
||||
4. Validate data quality with sample queries (Phase 2)
|
||||
5. Begin dataset collection (Phase 3)

## One-Sentence Summary
|
||||
|
||||
The n8n-mcp telemetry system successfully tracks 276K+ user interactions across a production Supabase backend, but lacks workflow mutation capture needed for building an n8n-fixer dataset. The solution requires a new table plus 3-4 weeks of integration work.

## Key Findings Summary
|
||||
|
||||
### What Exists Today
|
||||
- **276K+ telemetry events** tracked in Supabase
|
||||
- **6.5K+ unique workflows** analyzed
|
||||
- **12 event types** covering tool usage, errors, validation, workflow creation
|
||||
- **Production-grade infrastructure** with batching, retry logic, rate limiting
|
||||
- **Privacy-focused design** with sanitization, anonymization, encryption
|
||||
|
||||
### Critical Gaps for N8N-Fixer
|
||||
- No workflow mutation/modification tracking
|
||||
- No before/after workflow snapshots
|
||||
- No instruction/transformation capture
|
||||
- No mutation success metrics
|
||||
- No validation improvement tracking
|
||||
|
||||
### Proposed Solution
|
||||
- New `workflow_mutations` table (with 20 indexes)
|
||||
- Extended telemetry system to capture mutations
|
||||
- Instrumentation of 3-4 key tools

|
||||
---
|
||||
|
||||
## Storage & Cost Planning
|
||||
|
||||
### Conservative Estimate (10K mutations/month)
|
||||
- Storage: 250 MB/month
|
||||
- Cost: $10-20/month
|
||||
- Dataset: 1K mutations in 3-4 days
|
||||
|
||||
### Moderate Estimate (30K mutations/month)
|
||||
- Storage: 750 MB/month
|
||||
- Cost: $50-100/month
|
||||
- Dataset: 10K mutations in 10 days
|
||||
|
||||
### High Estimate (50K mutations/month)
|
||||
- Storage: 1.2 GB/month
|
||||
- Cost: $100-200/month
|
||||
- Dataset: 100K mutations in 2 months
|
||||
|
||||
**With 90-day retention policy, costs stay at lower end.**
|
||||
|
||||
---
|
||||
|
||||
## Questions Before Implementation
|
||||
|
||||
1. **Data Retention:** Keep mutations for 90 days? 1 year? Indefinite?
|
||||
2. **Storage Budget:** Monthly budget for telemetry storage?
|
||||
3. **Workflow Size:** Max workflow size to store? Compression required?
|
||||
4. **Dataset Timeline:** When do you need first dataset? (1K? 10K? 100K?)
|
||||
5. **Privacy:** Additional PII to sanitize beyond current approach?
|
||||
6. **User Consent:** Separate opt-in for mutation tracking vs. general telemetry?
|
||||

# Telemetry Workflow Mutation Tracking Specification
|
||||
|
||||
**Purpose:** Define the technical requirements for capturing workflow mutation data to build the n8n-fixer dataset
|
||||
|
||||
**Status:** Specification Document (Pre-Implementation)
|
||||
|
||||
---
|
||||
|
||||
## 1. Overview
|
||||
|
||||
This specification details how to extend the n8n-mcp telemetry system to capture:
|
||||
- **Before State:** Complete workflow JSON before modification
|
||||
- **Instruction:** The transformation instruction/prompt
|
||||
- **After State:** Complete workflow JSON after modification
|
||||
- **Metadata:** Timestamps, user ID, success metrics, validation states
|
||||
|
||||

||||
CREATE INDEX idx_mutations_workflow_id
|
||||
ON workflow_mutations(workflow_id, created_at DESC);
|
||||
|
||||
-- Mutation Success Rate
|
||||
CREATE INDEX idx_mutations_success
|
||||
ON workflow_mutations(mutation_success, created_at DESC);
|
||||
|
||||
-- Validation Improvement Analysis
|

-- Instruction Type Analysis
|
||||
CREATE INDEX idx_mutations_instruction_type
|
||||
ON workflow_mutations(instruction_type, created_at DESC);

CREATE INDEX idx_mutations_source_validation
|
||||
ON workflow_mutations(mutation_source, validation_improved, created_at DESC);
|
||||
```
|
||||
|
||||
### 2.3 Optional: Materialized View for Analytics
|
||||
|
||||

## 6. Data Quality & Validation
|
||||
|
||||
### 6.1 Mutation Validation Rules
|
||||
|
||||
```typescript
|
||||
// In src/telemetry/mutation-validator.ts
|
||||
|
||||
export class WorkflowMutationValidator {

||||
if (!mutation.before_workflow_json) errors.push('before_workflow_json required');
|
||||
if (!mutation.after_workflow_json) errors.push('after_workflow_json required');
|
||||
if (!mutation.before_workflow_hash) errors.push('before_workflow_hash required');
|
||||
if (!mutation.after_workflow_hash) errors.push('after_workflow_hash required');
|
||||
if (!mutation.instruction) errors.push('instruction is required');
|
||||
if (!mutation.instruction_type) errors.push('instruction_type is required');
|
||||
|
||||
// Hash verification
|
||||

|
||||
}
|
||||
if (afterHash !== mutation.after_workflow_hash) {
|
||||
errors.push('after_workflow_hash mismatch');
|
||||
}
|
||||
|
||||
// Deduplication: Skip if before == after
|
||||
if (beforeHash === afterHash) {
|
||||
errors.push('before and after states are identical (skipping)');
|
||||
}
|
||||
|
||||
// Size validation
|
||||
const beforeSize = JSON.stringify(mutation.before_workflow_json).length;
|
||||
const afterSize = JSON.stringify(mutation.after_workflow_json).length;
|
||||
|
||||
if (beforeSize > 10 * 1024 * 1024) {
|
||||
errors.push('before_workflow_json exceeds 10MB size limit');
|
||||
}
|
||||
if (afterSize > 10 * 1024 * 1024) {
|
||||
errors.push('after_workflow_json exceeds 10MB size limit');
|
||||
}
|
||||
|
||||
// Instruction validation
|
||||
if (mutation.instruction.length > 5000) {
|
||||
mutation.instruction = mutation.instruction.substring(0, 5000);
|
||||
}
|
||||
if (mutation.instruction.length < 3) {
|
||||
errors.push('instruction too short (min 3 chars)');
|
||||
}
|
||||
|
||||
// Error count validation
|
||||

|
||||

||||
}
|

||||
return {
|
||||
isValid: errors.length === 0,
|
||||
errors
|
||||
};
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 6.2 Data Compression Strategy
|
||||
|
||||
For large workflows (>1MB):
|
||||
|
||||
```typescript
|
||||
import { gzipSync, gunzipSync } from 'zlib';
|
||||
|
||||
export function compressWorkflow(workflow: any): {
|
||||
compressed: string; // base64
|
||||
originalSize: number;
|
||||
compressedSize: number;
|
||||
} {
|
||||
const json = JSON.stringify(workflow);
|
||||
const buffer = Buffer.from(json, 'utf-8');
|
||||
const compressed = gzipSync(buffer);
|
||||
const base64 = compressed.toString('base64');
|
||||
|
||||
return {
|
||||
compressed: base64,
|
||||
originalSize: buffer.length,
|
||||
compressedSize: compressed.length
|
||||
};
|
||||
}
|
||||
|
||||
export function decompressWorkflow(compressed: string): any {
|
||||
const buffer = Buffer.from(compressed, 'base64');
|
||||
const decompressed = gunzipSync(buffer);
|
||||
const json = decompressed.toString('utf-8');
|
||||
return JSON.parse(json);
|
||||
}
|
||||
```
|
||||

|
||||
|
||||
## 7. Query Examples for Analysis
|
||||
|
||||
### 7.1 Basic Mutation Statistics
|
||||
|
||||
```sql
|
||||
-- Overall mutation metrics
|
||||
SELECT
|
||||
COUNT(*) as total_mutations,
|
||||
COUNT(*) FILTER(WHERE mutation_success) as successful,
|
||||
COUNT(*) FILTER(WHERE validation_improved) as validation_improved,
|
||||
ROUND(100.0 * COUNT(*) FILTER(WHERE mutation_success) / COUNT(*), 2) as success_rate,
|
||||
ROUND(100.0 * COUNT(*) FILTER(WHERE validation_improved) / COUNT(*), 2) as improvement_rate,
|
||||
AVG(nodes_modified_count) as avg_nodes_modified,
|
||||
AVG(properties_modified_count) as avg_properties_modified,
|
||||
AVG(execution_duration_ms)::INTEGER as avg_duration_ms
|
||||
FROM workflow_mutations
|
||||
WHERE created_at >= NOW() - INTERVAL '7 days';
|
||||
```
|
||||
|
||||
### 7.2 Success by Instruction Type
|
||||
|
||||
```sql
|
||||
SELECT
|
||||
instruction_type,
|
||||
COUNT(*) as count,
|
||||
ROUND(100.0 * COUNT(*) FILTER(WHERE mutation_success) / COUNT(*), 2) as success_rate,
|
||||
ROUND(100.0 * COUNT(*) FILTER(WHERE validation_improved) / COUNT(*), 2) as improvement_rate,
|
||||
AVG(validation_errors_fixed) as avg_errors_fixed,
|
||||
AVG(new_errors_introduced) as avg_new_errors
|
||||
FROM workflow_mutations
|
||||
WHERE created_at >= NOW() - INTERVAL '30 days'
|
||||
GROUP BY instruction_type
|
||||
ORDER BY count DESC;
|
||||
```
|
||||
|
||||
### 7.3 Most Common Mutations
|
||||
|
||||
```sql
|
||||
SELECT
|
||||
properties_modified,
|
||||
COUNT(*) as frequency,
|
||||
ROUND(100.0 * COUNT(*) / (SELECT COUNT(*) FROM workflow_mutations
|
||||
WHERE created_at >= NOW() - INTERVAL '30 days'), 2) as percentage
|
||||
FROM workflow_mutations
|
||||
WHERE created_at >= NOW() - INTERVAL '30 days'
|
||||
ORDER BY frequency DESC
|
||||
LIMIT 20;
|
||||
```

### 7.4 Complexity Impact
|
||||
|
||||
```sql
|
||||
SELECT
|
||||
complexity_before,
|
||||
complexity_after,
|
||||
COUNT(*) as transitions,
|
||||
ROUND(100.0 * COUNT(*) FILTER(WHERE mutation_success) / COUNT(*), 2) as success_rate
|
||||
FROM workflow_mutations
|
||||
WHERE created_at >= NOW() - INTERVAL '30 days'

---
|
||||
|
||||
## 9. Security & Privacy Considerations
|
||||
|
||||
- **No Credentials:** Sanitizer strips credentials before storage
|
||||
- **No Secrets:** Workflow secret references removed
|
||||
- **User Anonymity:** User ID is anonymized
|
||||
- **Hash Verification:** All workflow hashes verified before storage
|
||||
- **Size Limits:** 10MB max per workflow (with compression option)
|
||||
- **Retention:** Define data retention policy separately
|
||||
- **Encryption:** Enable Supabase encryption at rest
|
||||
- **Access Control:** Restrict table access to application-level only
|
||||
|
||||
---
|
||||
|
||||
## 10. Performance Considerations
|
||||
|
||||
| Aspect | Target | Strategy |
|
||||
|--------|--------|----------|
|
||||
| **Batch Flush** | <5s latency | 5-second flush interval + auto-flush |
|
||||
| **Large Workflows** | >1MB support | Gzip compression + base64 encoding |
|
||||
| **Query Performance** | <100ms | Strategic indexing + materialized views |
|
||||
| **Storage Growth** | <50GB/month | Compression + retention policies |
|
||||
| **Network Throughput** | <1MB/batch | Compress before transmission |

# N8N-Fixer Dataset: Telemetry Infrastructure Analysis
|
||||
|
||||
**Analysis Completed:** November 12, 2025
|
||||
**Scope:** N8N-MCP Telemetry Database Schema & Workflow Mutation Tracking
|
||||
**Status:** Ready for Implementation Planning
|
||||
|
||||
---
|
||||
|
||||
## Overview
|
||||
|
||||
This document synthesizes a comprehensive analysis of the n8n-mcp telemetry infrastructure and provides actionable recommendations for building an n8n-fixer dataset with before/instruction/after workflow snapshots.
|
||||
|
||||
**Key Findings:**
|
||||
- Telemetry system is production-ready with 276K+ events tracked
|
||||
- Supabase PostgreSQL backend stores all events
|
||||
- Current system **does NOT capture workflow mutations** (before→after transitions)
|
||||
- Requires new table + instrumentation to collect fixer dataset
|
||||
- Implementation is straightforward with 3-4 weeks of development
|
||||

|
||||
|
||||
---
|
||||
|
||||
### Phase 3: Tool Integration (1 week)
|
||||
Instrument 3 key tools to capture mutations:
|
||||
|
||||
1. **n8n_autofix_workflow**
|
||||
- Before: Broken workflow
|
||||
- Instruction: "Auto-fix validation errors"
|

- Type: `user_provided`
|
||||
|
||||
3. **Validation Engine** (if applicable)
|
||||
- Before: Invalid workflow
|
||||
- Instruction: Validation correction
|
||||
- After: Valid workflow
|
||||
- Type: `validation_correction`
|
||||
|
||||
---
|
||||
|
||||
### Phase 4: Validation & Analysis (1 week)
|
||||
1. Data quality verification
|
||||
- Hash validation
|
||||
- Size checks
|
||||
- Deduplication effectiveness
|
||||
|
||||
2. Sample query execution
|
||||
- Success rate by instruction type
|
||||
- Common mutations
|
||||
- Complexity impact
|
||||
|
||||
3. Dataset assessment
|
||||
- Volume estimates
|
||||
- Data distribution
|
||||
- Quality metrics
|
||||
|
||||
---
|
||||
|
||||
## Key Metrics You'll Collect
|
||||
|
||||
### Per Mutation Record
|
||||
- **Identification:** User ID, Workflow ID, Timestamp
|
||||
- **Before State:** Full workflow JSON, hash, validation status
|
||||
- **Instruction:** The transformation prompt/directive
|
||||
- **After State:** Full workflow JSON, hash, validation status
|
||||
- **Changes:** Nodes modified, properties changed, connections modified
|
||||
- **Outcome:** Success boolean, validation improvement, errors fixed
|
||||
|
||||
### Aggregate Analysis
|
||||
```sql
|
||||
-- Success rates by instruction type
|
||||
SELECT instruction_type, COUNT(*) as count,
|
||||
ROUND(100.0 * COUNT(*) FILTER(WHERE mutation_success) / COUNT(*), 2) as success_rate
|
||||
FROM workflow_mutations
|
||||
GROUP BY instruction_type;
|
||||
|
||||
-- Validation improvement distribution
|
||||
SELECT validation_errors_fixed, COUNT(*) as count
|
||||
FROM workflow_mutations
|
||||
WHERE validation_improved = true
|
||||
GROUP BY 1
|
||||
ORDER BY 2 DESC;
|
||||
|
||||
-- Complexity transitions
|
||||
SELECT complexity_before, complexity_after, COUNT(*) as transitions
|
||||
FROM workflow_mutations
|
||||
GROUP BY 1, 2;
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Storage Requirements
|
||||
|
||||
### Data Size Estimates
|
||||
```
|
||||
Average Before Workflow: 10 KB
|
||||
Average After Workflow: 10 KB
|
||||
Average Instruction: 500 B
|
||||
Indexes & Metadata: 5 KB
|
||||
Per Mutation Total: 25 KB
|
||||
|
||||
Monthly Mutations (estimate): 10K-50K
|
||||
Monthly Storage: 250 MB - 1.2 GB
|
||||
Annual Storage: 3-14 GB
|
||||
```
|
||||
|
||||
### Optimization Strategies
|
||||
1. **Compression:** Gzip workflows >1MB
|
||||
2. **Deduplication:** Skip identical before/after pairs
|
||||
3. **Retention:** Define archival policy (90 days? 1 year?)
|
||||
4. **Indexing:** Materialized views for common queries
|
||||
|
||||

|
||||
|
||||
## Data Safety & Privacy
|
||||
|
||||
### Current Protections
|
||||
- User IDs are anonymized
|
||||
- Credentials are stripped from workflows
|
||||
- Email addresses are masked [EMAIL]
|
||||
- API keys are masked [KEY]
|
||||
- URLs are masked [URL]
|
||||
- Error messages are sanitized
|
||||
|
||||
### For Mutations Table
|
||||
- Continue PII sanitization
|
||||
- Hash verification for integrity
|
||||
- Size limits (10 MB per workflow with compression)
|
||||
- User consent (telemetry opt-in)
|
||||
|
||||
---
|
||||
|
||||
## Integration Points
|
||||
|
||||
### Where to Add Tracking Calls
|
||||
```typescript
|
||||
// In n8n_autofix_workflow
|
||||
await telemetry.trackWorkflowMutation(
|
||||
originalWorkflow,
|
||||
'Auto-fix validation errors',
|
||||
fixedWorkflow,
|
||||
{ instructionType: 'auto_fix', success: true }
|
||||
);
|
||||
|
||||
// In n8n_update_partial_workflow
|
||||
await telemetry.trackWorkflowMutation(
|
||||
currentWorkflow,
|
||||
formatOperationsAsInstruction(operations),
|
||||
updatedWorkflow,
|
||||
{ instructionType: 'user_provided' }
|
||||
);
|
||||
```
|
||||
|
||||
### No Breaking Changes
|
||||
- Fully backward compatible
|
||||
- Existing telemetry unaffected
|
||||
- Optional feature (can disable if needed)
|
||||
- Doesn't require version bump
|
||||

## Risk Assessment
|
||||
|
||||
### Low Risk
|
||||
- No changes to existing event system
|
||||
- Supabase table addition is non-breaking
|
||||
- TypeScript types only (no runtime impact)
|
||||
|
||||
### Medium Risk
|
||||
- Large workflows may impact performance if not compressed
|
||||
- Storage costs if dataset grows faster than estimated
|
||||
- Mitigation: Compression + retention policy
|
||||
|
||||
### High Risk
|
||||
- None identified if implemented as specified

|
||||
|
||||
## Useful Commands
|
||||
|
||||
### View Current Telemetry Tables
|
||||
```sql
|
||||
SELECT table_name FROM information_schema.tables
|
||||
WHERE table_schema = 'public'
|
||||
AND table_name LIKE 'telemetry%';
|
||||
```
|
||||
|
||||
### Count Current Events
|
||||
```sql
|
||||
SELECT event, COUNT(*) FROM telemetry_events
|
||||
GROUP BY event ORDER BY 2 DESC;
|
||||
```
|
||||
|
||||
### Check Workflow Deduplication Rate
|
||||
```sql
|
||||
SELECT COUNT(*) as total,
|
||||
COUNT(DISTINCT workflow_hash) as unique
|
||||
FROM telemetry_workflows;
|
||||
```

## Summary
|
||||
|
||||
The n8n-mcp telemetry infrastructure is mature, privacy-conscious, and well-designed. It currently tracks user interactions effectively but lacks workflow mutation capture needed for the n8n-fixer dataset.
|
||||
|
||||
**The solution is straightforward:** Add a single `workflow_mutations` table, extend the tracking system, and instrument 3-4 key tools.
|
||||
|
||||
**Implementation effort:** 3-4 weeks for a complete, production-ready system.
|
||||
|
||||
**Result:** A high-quality dataset of before/instruction/after workflow transformations suitable for training ML models to fix broken n8n workflows automatically.

```
|
||||
|
||||
---
|
||||
|
||||
## Workflow Metadata Table Queries
|
||||
|
||||
### Workflow Complexity Distribution
|
||||
```sql
|
||||
SELECT
|
||||
complexity,
|
||||
COUNT(*) as count,
|
||||
AVG(node_count) as avg_nodes,

MAX(node_count) as max_nodes
|
||||
FROM telemetry_workflows
|
||||
GROUP BY complexity
|
||||
ORDER BY count DESC;
|
||||
```
|
||||
|
||||
### Most Common Node Type Combinations
|
||||
```sql
|
||||
SELECT
|
||||
node_types,
|
||||
COUNT(*) as frequency
|
||||
FROM telemetry_workflows
|
||||
GROUP BY node_types
|
||||
ORDER BY frequency DESC
|
||||
LIMIT 20;
|
||||
```
|
||||
|
||||
### Workflows with Triggers vs Webhooks
|

|
||||
FROM telemetry_workflows
|
||||
GROUP BY 1, 2;
|
||||
```
|
||||
|
||||
### Deduplicated Workflows (by hash)
|
||||
```sql
|
||||
SELECT
|
||||
COUNT(DISTINCT workflow_hash) as unique_workflows,
|
||||
COUNT(*) as total_rows,
|
||||
COUNT(DISTINCT user_id) as unique_users
|
||||
FROM telemetry_workflows;
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Common Analysis Patterns
|
||||
|
||||
### 1. User Journey Analysis
|
||||
```sql
|
||||
-- Tool usage patterns for a user (anonymized)
|
||||
WITH user_events AS (
|
||||
SELECT
|
||||
user_id,
|
||||
event,
|
||||
properties->>'tool' as tool,
|
||||
created_at,
|
||||
LAG(event) OVER(PARTITION BY user_id ORDER BY created_at) as prev_event
|
||||
FROM telemetry_events
|
||||
WHERE event IN ('tool_used', 'tool_sequence')
|
||||
AND created_at >= NOW() - INTERVAL '7 days'
|
||||
)
|
||||
SELECT
|
||||
prev_event,
|
||||
event,
|
||||
COUNT(*) as transitions
|
||||
FROM user_events
|
||||
WHERE prev_event IS NOT NULL
|
||||
GROUP BY 1, 2
|
||||
ORDER BY 3 DESC
|
||||
LIMIT 20;
|
||||
```
|
||||
|
||||
### 2. Performance Trends
|
||||
```sql
|
||||
-- Tool execution performance over time
|
||||
WITH perf_data AS (
|
||||
SELECT
|
||||
properties->>'tool' as tool,
|
||||
(properties->>'duration')::int as duration,
|
||||
DATE(created_at) as date
|
||||
FROM telemetry_events
|
||||
WHERE event = 'tool_used'
|
||||
AND created_at >= NOW() - INTERVAL '30 days'
|
||||
)
|
||||
SELECT
|
||||
date,
|
||||
tool,
|
||||
COUNT(*) as executions,
|
||||
AVG(duration)::INTEGER as avg_duration_ms,
|
||||
PERCENTILE_CONT(0.95) WITHIN GROUP(ORDER BY duration) as p95_duration_ms,
|
||||
MAX(duration) as max_duration_ms
|
||||
FROM perf_data
|
||||
GROUP BY date, tool
|
||||
ORDER BY date DESC, tool;
|
||||
```
|
||||
|
||||
### 3. Error Analysis with Context
|
||||
```sql
|
||||
-- Recent errors with affected tools
|
||||
SELECT
|
||||
properties->>'errorType' as error_type,
|
||||
properties->>'tool' as affected_tool,
|
||||
properties->>'context' as context,
|
||||
COUNT(*) as occurrences,
|
||||
MAX(created_at) as most_recent,
|
||||
COUNT(DISTINCT user_id) as users_affected
|
||||
FROM telemetry_events
|
||||
WHERE event = 'error_occurred'
|
||||
AND created_at >= NOW() - INTERVAL '24 hours'
|
||||
GROUP BY 1, 2, 3
|
||||
ORDER BY 4 DESC, 5 DESC;
|
||||
```
|
||||
|
||||
### 4. Node Configuration Patterns
|
||||
```sql
|
||||
-- Most configured nodes and their complexity
|
||||
WITH config_data AS (
|
||||
SELECT
|
||||
properties->>'nodeType' as node_type,
|
||||
(properties->>'propertiesSet')::int as props_set,
|
||||
properties->>'usedDefaults' = 'true' as used_defaults
|
||||
FROM telemetry_events
|
||||
WHERE event = 'node_configuration'
|
||||
AND created_at >= NOW() - INTERVAL '30 days'
|
||||
)
|
||||
SELECT
|
||||
node_type,
|
||||
COUNT(*) as configurations,
|
||||
AVG(props_set)::INTEGER as avg_props_set,
|
||||
ROUND(100.0 * SUM(CASE WHEN used_defaults THEN 1 ELSE 0 END)
|
||||
/ COUNT(*), 2) as default_usage_rate
|
||||
FROM config_data
|
||||
GROUP BY node_type
|
||||
ORDER BY 2 DESC
|
||||
LIMIT 20;
|
||||
```
|
||||
|
||||
### 5. Search Effectiveness
|
||||
```sql
|
||||
-- Search queries and their success
|
||||
SELECT
|
||||
properties->>'searchType' as search_type,
|
||||
COUNT(*) as total_searches,
|
||||
COUNT(*) FILTER(WHERE (properties->>'hasResults')::boolean) as with_results,
|
||||
ROUND(100.0 * COUNT(*) FILTER(WHERE (properties->>'hasResults')::boolean)
|
||||
/ COUNT(*), 2) as success_rate,
|
||||
AVG((properties->>'resultsFound')::int) as avg_results
|
||||
FROM telemetry_events
|
||||
WHERE event = 'search_query'
|
||||
AND created_at >= NOW() - INTERVAL '7 days'
|
||||
GROUP BY 1
|
||||
ORDER BY 2 DESC;
|
||||
```
|
||||

|
||||
ORDER BY 3 DESC;
|
||||
```
|
||||
|
||||
### User Retention Analysis
|
||||

||||
WHERE created_at >= NOW() - INTERVAL '90 days'
|
||||
GROUP BY 1
|
||||
)
|
||||
SELECT week, active_users
|
||||
FROM weekly_users
|
||||
ORDER BY week DESC;
|
||||
```
|
||||
|
||||
### Platform Usage Breakdown
|
||||
