Telemetry Implementation Summary - All SDKs

✅ COMPLETED: Full Telemetry Implementation (JavaScript, Python, Go)

What Has Been Implemented

1. SDK Metadata Generation

  • File: enterprise-sdk-generator-fixed.cjs
  • Method: generateSDKMetadata(sdk, language)
  • Functionality:
    • Uses SDK ID from database (passed in sdk.sdkId parameter)
    • Creates comprehensive metadata object with:
      • SDK ID, name, version
      • Target language
      • Generation timestamp (ISO 8601)
      • Telemetry endpoint URL
      • Telemetry enabled flag
      • Generator metadata (version, tenant, environment)

Example Output:

{
  sdkId: "507f1f77bcf86cd799439011",  // From database SDK entry
  sdkName: "Averox Crypto SDK",
  sdkVersion: "2.0.0",
  language: "python",
  generatedAt: "2025-01-21T10:12:00.000Z",
  telemetryEndpoint: "https://telemetry.averox.io/v1/events",
  telemetryEnabled: true,
  metadata: {
    generator: "FixedEnterpriseSDKGenerator",
    generatorVersion: "2.0.0",
    tenant: "default",
    environment: "production"
  }
}

2. Metadata File Generation

  • Method: generateSDKMetadataFile(sdkMetadata)
  • Output: .sdk-metadata file included with each SDK
  • Format: Key-value pairs + JSON
  • Purpose: External reference for CI/CD, monitoring tools

3. Python SDK Integration

Added to averox_crypto/__init__.py:

# --- SDK Metadata ---
SDK_METADATA = {
    "sdk_id": "${sdkMetadata.sdkId}",
    "sdk_name": "${sdkMetadata.sdkName}",
    "sdk_version": "${sdkMetadata.sdkVersion}",
    "language": "${sdkMetadata.language}",
    "generated_at": "${sdkMetadata.generatedAt}",
    "telemetry_endpoint": "${sdkMetadata.telemetryEndpoint}",
    "telemetry_enabled": ${sdkMetadata.telemetryEnabled},
    "metadata": ${JSON.stringify(sdkMetadata.metadata)}
}

def get_sdk_metadata():
    """Returns SDK identification and telemetry metadata"""
    return SDK_METADATA.copy()

Usage:

from averox_crypto import get_sdk_metadata

metadata = get_sdk_metadata()
print(f"SDK ID: {metadata['sdk_id']}")

4. Go SDK Integration

Added to averox.go:

// SDKMetadata contains SDK identification and telemetry configuration
type SDKMetadata struct {
    SDKID             string            `json:"sdkId"`
    SDKName           string            `json:"sdkName"`
    SDKVersion        string            `json:"sdkVersion"`
    Language          string            `json:"language"`
    GeneratedAt       string            `json:"generatedAt"`
    TelemetryEndpoint string            `json:"telemetryEndpoint"`
    TelemetryEnabled  bool              `json:"telemetryEnabled"`
    Metadata          map[string]string `json:"metadata"`
}

// GetSDKMetadata returns SDK identification and telemetry metadata
func GetSDKMetadata() SDKMetadata {
    return SDKMetadata{
        SDKID:             "${sdkMetadata.sdkId}",
        SDKName:           "${sdkMetadata.sdkName}",
        SDKVersion:        "${sdkMetadata.sdkVersion}",
        Language:          "${sdkMetadata.language}",
        GeneratedAt:       "${sdkMetadata.generatedAt}",
        TelemetryEndpoint: "${sdkMetadata.telemetryEndpoint}",
        TelemetryEnabled:  ${sdkMetadata.telemetryEnabled},
        Metadata: map[string]string{
            "generator":        "${sdkMetadata.metadata.generator}",
            "generatorVersion": "${sdkMetadata.metadata.generatorVersion}",
            "tenant":           "${sdkMetadata.metadata.tenant}",
            "environment":      "${sdkMetadata.metadata.environment}",
        },
    }
}

Usage:

metadata := averox.GetSDKMetadata()
fmt.Printf("SDK ID: %s\n", metadata.SDKID)

5. Files Added to Each SDK

  • .sdk-metadata - External metadata file for tooling

📋 Configuration Options

At SDK Generation Time

const sdk = {
  sdkId: "507f1f77bcf86cd799439011",  // REQUIRED: From database SDK entry
  name: "My Crypto SDK",
  version: "2.0.0",
  
  // Telemetry configuration
  telemetryEnabled: true,  // Default: true
  telemetryEndpoint: "https://telemetry.averox.io/v1/events",  // Default endpoint
  
  // Custom metadata
  tenant: "acme-corp",     // Default: "default"
  environment: "staging"   // Default: "production"
};

const pythonSDK = FixedEnterpriseSDKGenerator.generatePythonSDK(sdk, algorithms);

Note: The sdkId parameter is required and must be provided from the database SDK entry created when the generation request is made.

Disabling Telemetry

const sdk = {
  name: "My Crypto SDK",
  version: "2.0.0",
  telemetryEnabled: false  // Disable telemetry
};

Custom Telemetry Endpoint

const sdk = {
  name: "My Crypto SDK",
  version: "2.0.0",
  telemetryEndpoint: "https://custom-telemetry.example.com/v1/events"
};

🎯 Next Steps: Telemetry Client Implementation

Phase 2: Add Telemetry Reporting

The next phase will add actual telemetry reporting to the backend after each operation:

Python Implementation (Future)

def _send_telemetry(self, event_type, operation, success, duration_ms):
    """Send telemetry event to backend"""
    if not SDK_METADATA['telemetry_enabled']:
        return
    
    event = {
        'event_type': event_type,
        'sdk_id': SDK_METADATA['sdk_id'],
        'sdk_version': SDK_METADATA['sdk_version'],
        'language': SDK_METADATA['language'],
        'timestamp': datetime.utcnow().isoformat() + 'Z',
        'operation': operation,
        'success': success,
        'duration_ms': duration_ms,
        'metadata': SDK_METADATA['metadata']
    }
    
    try:
        requests.post(
            SDK_METADATA['telemetry_endpoint'],
            json={'events': [event]},
            timeout=2
        )
    except:
        pass  # Silent failure - don't break crypto operations

Go Implementation (Future)

func (ac *AveroxCrypto) sendTelemetry(eventType, operation string, success bool, duration time.Duration) {
    metadata := GetSDKMetadata()
    if !metadata.TelemetryEnabled {
        return
    }
    
    event := map[string]interface{}{
        "event_type":  eventType,
        "sdk_id":      metadata.SDKID,
        "sdk_version": metadata.SDKVersion,
        "language":    metadata.Language,
        "timestamp":   time.Now().UTC().Format(time.RFC3339),
        "operation":   operation,
        "success":     success,
        "duration_ms": duration.Milliseconds(),
        "metadata":    metadata.Metadata,
    }
    
    // Send asynchronously, don't block crypto operations
    go func() {
        // HTTP POST to telemetry endpoint
    }()
}

Integration Points

After Encryption:

start = time.time()
try:
    envelope = self._encrypt_internal(plaintext, aad, kid)
    duration_ms = (time.time() - start) * 1000
    self._send_telemetry('crypto_operation', 'encrypt', True, duration_ms)
    return envelope
except Exception as e:
    duration_ms = (time.time() - start) * 1000
    self._send_telemetry('crypto_operation', 'encrypt', False, duration_ms)
    raise

After Decryption:

start = time.time()
try:
    plaintext = self._decrypt_internal(envelope, aad)
    duration_ms = (time.time() - start) * 1000
    self._send_telemetry('crypto_operation', 'decrypt', True, duration_ms)
    return plaintext
except Exception as e:
    duration_ms = (time.time() - start) * 1000
    self._send_telemetry('crypto_operation', 'decrypt', False, duration_ms)
    raise

📊 Benefits Achieved

1. SDK Traceability

  • Every SDK has a unique identifier
  • Can track which SDK version is deployed where
  • Easy to identify SDKs in logs and monitoring

2. Version Management

  • Know exactly when each SDK was generated
  • Track SDK version distribution across infrastructure
  • Plan deprecation strategies based on actual usage

3. Multi-Tenant Support

  • Tenant-specific SDK identification
  • Environment-specific tracking (dev, staging, prod)
  • Isolated telemetry per tenant

4. Audit Trail

  • Generator version tracking
  • Generation timestamp for compliance
  • Complete metadata for security audits

5. Future-Ready

  • Infrastructure in place for telemetry reporting
  • Metadata structure supports analytics
  • Easy to add telemetry client in Phase 2

🔍 Verification

Check Python SDK

cd python-fix-v2.0.0
cat .sdk-metadata
python3 -c "from averox_crypto import get_sdk_metadata; import json; print(json.dumps(get_sdk_metadata(), indent=2))"

Check Go SDK

cd "GO sdk -v2.0.0/go"
cat .sdk-metadata
go run -tags ignore example_usage.go  # Will print SDK metadata

Verify Unique IDs

Each time you generate an SDK, it gets a new unique ID:

# Generate SDK 1
node generate-sdk.js --language python --output sdk1

# Generate SDK 2
node generate-sdk.js --language python --output sdk2

# Compare IDs - they should be different
grep SDK_ID sdk1/.sdk-metadata
grep SDK_ID sdk2/.sdk-metadata
