Error Tracking & Monitoring

Optima's Error Tracking provides comprehensive JavaScript error monitoring with detailed stack traces, user context, and performance correlation. Understand exactly what users experienced when errors occurred and get the context needed to fix issues quickly.

🐛 Comprehensive Error Capture

JavaScript Error Monitoring

Automatically capture all JavaScript errors:

• Uncaught Exceptions: Runtime errors that crash functionality
• Promise Rejections: Unhandled async operation failures
• Network Errors: Failed API calls and resource loading
• Custom Errors: Application-specific error tracking
• Framework Errors: React, Vue, Angular error boundaries

Error Classification

Organize and prioritize errors effectively:

• Error Types: TypeError, ReferenceError, SyntaxError, etc.
• Severity Levels: Critical, high, medium, low priority
• Error Frequency: How often each error occurs
• User Impact: Number of users affected by each error
• Performance Impact: How errors affect application performance

📊 Detailed Error Context

Stack Trace Analysis

User Context

Understand the user's situation when errors occurred:

Session Information

• User agent and browser details
• Device type and screen resolution
• Operating system and version
• Network connection type
• Geographic location (anonymized)

Application State

• Current page/route when error occurred

🎯 Advanced Error Analysis

Error Grouping

Intelligent error organization:

• Automatic Grouping: Similar errors grouped together
• Custom Grouping Rules: Define your own grouping logic

• Duplicate Detection: Avoid noise from repeated errors
• Trend Analysis: Track error patterns over time

Impact Assessment

Understand the business impact:

• User Conversion Impact: How errors affect conversion rates
• Revenue Impact: Financial cost of errors
• User Experience Degradation: Performance impact of errors
• Feature Adoption: How errors prevent feature usage
• Customer Satisfaction: Error correlation with user feedback

Error Correlation

Connect errors with other data:

• Performance Correlation: Errors related to slow performance
• User Journey Impact: How errors disrupt user flows
• Device/Browser Patterns: Error patterns by environment
• Geographic Distribution: Regional error variations
• Time-based Patterns: When errors are most likely to occur

🔧 Integration & Setup

Automatic Error Capture

Zero-configuration error monitoring:

// Automatic error capture with Optima SDK
<script src="https://cdn.optimajs.com/optima-sdk.js"></script>
<script>
  Optima.init({
    apiKey: 'your-api-key',
    // Error tracking automatically enabled
    errorTracking: {
      captureUnhandledRejections: true,
      captureConsoleErrors: true,
      maxBreadcrumbs: 50
    }
  });
</script>

Custom Error Tracking

Track application-specific errors:

// Manual error reporting
try {
  riskyOperation();
} catch (error) {
  Optima.captureError(error, {
    level: 'error',
    tags: {
      component: 'checkout',
      feature: 'payment'
    },
    extra: {
      orderId: '12345',
      paymentMethod: 'credit_card'
    }
  });
}

// Custom error context
Optima.setUserContext({
  id: 'user123',
  email: 'user@example.com',
  plan: 'premium'
});

Optima.addBreadcrumb({
  message: 'User clicked checkout button',
  category: 'ui',
  level: 'info'
});

🚨 Alerting & Notifications

Smart Alerting

Get notified about important errors:

• Threshold Alerts: When error rates exceed limits
• New Error Alerts: When new error types appear
• Regression Alerts: When fixed errors reappear
• Volume Alerts: When error volume spikes unexpectedly
• User Impact Alerts: When errors affect many users

Notification Channels

Choose how you want to be notified:

• Email Notifications: Detailed error reports via email
• Slack Integration: Real-time alerts in team channels
• Webhook Support: Custom integrations with your tools
• Mobile Notifications: Push alerts for critical errors
• Dashboard Alerts: In-app notification system

Alert Configuration

Customize your notification preferences:

// Configure error alerts
Optima.configureAlerts({
  errorRate: {
    threshold: 5, // errors per minute
    window: '5m',
    notification: ['email', 'slack']
  },
  newErrors: {
    enabled: true,
    notification: ['slack']
  },
  criticalErrors: {
    keywords: ['payment', 'checkout', 'login'],
    notification: ['email', 'slack', 'webhook']
  }
});

🔍 Debugging Tools

Error Investigation

🚀 Best Practices

Error Prevention

Proactive approaches to reduce errors:

1. Code Quality: Use linting and type checking
2. Testing Strategy: Comprehensive test coverage
3. Error Boundaries: Implement proper error handling
4. Input Validation: Validate user inputs thoroughly
5. Graceful Degradation: Handle failures gracefully

Error Response

Effective error management workflow:

1. Rapid Detection: Set up proper alerting
2. Quick Assessment: Evaluate error impact and priority
3. Investigation: Use error context for debugging
4. Resolution: Fix root cause, not just symptoms
5. Prevention: Implement measures to prevent recurrence

Team Workflow

Organize error handling across your team:

• Error Ownership: Clear responsibility for error types
• Response Times: SLA for different error severities
• Escalation Process: When and how to escalate errors
• Documentation: Maintain error resolution knowledge base
• Review Process: Regular error trend analysis
