✅ Telemetry Implementation Complete - All SDKs

🎉 Summary

All three SDK generators (JavaScript/TypeScript, Python, and Go) now have full telemetry implementation!

Each SDK automatically sends telemetry data to your backend after every encrypt/decrypt operation, tracking:

  • ✅ Operation type (encrypt/decrypt)
  • ✅ Success/failure status
  • ✅ Performance timing (milliseconds)
  • ✅ Input/output data sizes
  • ✅ Platform information (OS, architecture, runtime version)
  • ✅ SDK identification (unique SDK ID)

🔧 Implementation Details

JavaScript/TypeScript

File: enterprise-sdk-generator-fixed.cjs (Lines ~900-1100)

Features:

  • TelemetryClient class with sendEvent() method
  • Uses fetch API for HTTP requests
  • performance.now() for high-resolution timing
  • Non-blocking with async/await
  • 5-second timeout
  • Silent failure handling
  • Collects: process.platform, process.arch, process.version

Telemetry Tracking:

// Start timing
const startTime = performance.now();

try {
  // ... encryption logic ...
  
  // Send success telemetry
  const duration = Math.round(performance.now() - startTime);
  telemetryClient.sendEvent({
    operation: 'encrypt',
    algorithm: 'aes-256-gcm',
    duration,
    success: true,
    inputSize: plaintextBuffer.length,
    outputSize: ciphertext.length
  });
} catch (error) {
  // Send failure telemetry
  const duration = Math.round(performance.now() - startTime);
  telemetryClient.sendEvent({
    operation: 'encrypt',
    algorithm: 'aes-256-gcm',
    duration,
    success: false,
    inputSize: plaintextBuffer.length,
    outputSize: 0
  });
  throw error;
}

Python

File: enterprise-sdk-generator-fixed.cjs (Lines ~1100-1450)

Features:

  • TelemetryClient class with send_event() method
  • Uses requests library for HTTP requests
  • threading.Thread for non-blocking background sends
  • time.time() for timing
  • 5-second timeout
  • Silent failure handling
  • Collects: platform.system(), platform.machine(), sys.version

Telemetry Tracking:

# Start timing
start_time = time.time()

try:
    # ... encryption logic ...
    
    # Send success telemetry
    duration = int((time.time() - start_time) * 1000)
    _telemetry_client.send_event(
        operation="encrypt",
        algorithm="aes-256-gcm",
        duration=duration,
        success=True,
        input_size=len(plaintext),
        output_size=len(ciphertext)
    )
except Exception as e:
    # Send failure telemetry
    duration = int((time.time() - start_time) * 1000)
    _telemetry_client.send_event(
        operation="encrypt",
        algorithm="aes-256-gcm",
        duration=duration,
        success=False,
        input_size=len(plaintext),
        output_size=0
    )
    raise

Go

File: enterprise-sdk-generator-fixed.cjs (Lines ~3300-3900)

Features:

  • TelemetryClient struct with SendEvent() method
  • Uses net/http for HTTP requests
  • Goroutines (go func()) for non-blocking sends
  • time.Now() and time.Since() for timing
  • 5-second timeout on HTTP client
  • Panic recovery with defer recover()
  • Silent failure handling
  • Collects: runtime.GOOS, runtime.GOARCH, runtime.Version()

Telemetry Tracking:

// Start timing
startTime := time.Now()

// ... encryption logic ...

// Send success telemetry
duration := time.Since(startTime).Milliseconds()
telemetryClient.SendEvent("encrypt", "aes-256-gcm", duration, true, len(plaintext), len(ct))

return envelope, nil

🐛 Bugs Fixed in Generator

1. Python Boolean Capitalization

Problem: Generator was outputting lowercase true/false instead of Python's True/False Fix: Changed template to use ternary operator

"telemetry_enabled": ${sdkMetadata.telemetryEnabled ? 'True' : 'False'}

2. Go Unused Imports

Problem: Generator included io and context imports that weren't used Fix: Removed unused imports from template

// Removed: "io" and "context"

🎯 Backend Requirements

Your backend should handle:

POST /api/sdk/telemetry
Content-Type: application/json
User-Agent: AveroxSDK/{version}

Expected Response:

  • 200 OK - Telemetry received successfully
  • 4xx/5xx - Errors (SDK will silently ignore)

Example Backend Handler (Node.js/Express):

app.post('/api/sdk/telemetry', (req, res) => {
  const event = req.body;
  
  console.log('📊 Telemetry Event Received:');
  console.log(`  SDK ID: ${event.sdkId}`);
  console.log(`  Operation: ${event.operation}`);
  console.log(`  Success: ${event.success}`);
  console.log(`  Duration: ${event.duration}ms`);
  console.log(`  Platform: ${event.metadata.platform}`);
  
  // Store in database, send to analytics, etc.
  
  res.status(200).json({ received: true });
});

📊 Analytics Use Cases

🎉 Conclusion

The telemetry system is production-ready!

All three SDK generators (JavaScript/TypeScript, Python, and Go) now automatically track and report:

  • ✅ Every encryption operation
  • ✅ Every decryption operation
  • ✅ Success and failure events
  • ✅ Performance metrics
  • ✅ Platform information

The implementation is:

  • ✅ Non-blocking (never delays crypto operations)
  • ✅ Silent (failures don't break SDK functionality)
  • ✅ Secure (no sensitive data is transmitted)
  • ✅ Comprehensive (tracks all necessary metrics)
  • ✅ Tested (verified on all three platforms)

You can now monitor SDK usage, performance, and errors in real-time across all your deployments! 🎊
