Network Monitoring

The Embrace SDK automatically monitors network requests made through fetch or XMLHttpRequest in your application, providing visibility into network performance, errors, and behavior.

How Network Monitoring Works​

The SDK leverages the @opentelemetry/instrumentation-fetch and @opentelemetry/instrumentation-xml-http-request instrumentation packages from OpenTelemetry to intercept network requests and capture them as spans.

This automatic instrumentation gives you immediate visibility into all network activity without requiring manual code changes.

Key Benefits​

  • Track network request timing and performance
  • Identify slow or failing API endpoints
  • Monitor request/response sizes
  • Troubleshoot network errors
  • Correlate network activity with user actions and app behavior

Configuration Options​

Network monitoring behavior can be customized through the process described in Configuring Automatic Instrumentation. Specific configuration options can be found in the @opentelemetry/instrumentation-fetch and @opentelemetry/instrumentation-xml-http-request package documentations.

Data Captured​

For each network request, the SDK captures:

  • Request URL
  • HTTP method
  • Status code
  • Start and end time
  • Duration
  • Error information (for failed requests)

Integration with Other Features​

Network monitoring integrates with other Embrace features:

  • Network spans are associated with the current session
  • Custom dashboards can be built to monitor response times to identify slow endpoints
  • Alerts can be set on error rates to surface problematic services
