HTTP REST Api endpoint http_metrics

• /http_metrics

  • Supported for both: OpenTSDB API and Prometheus API

  • Provides detailed performance metrics for HTTP requests processed by the grafana-bridge. This endpoint exposes execution time statistics that help administrators:

    Monitor overall performance: Track total HTTP request execution time to identify performance degradation Analyze backend wait times: Measure time spent waiting for backend responses to pinpoint bottlenecks Identify slow queries: Detect which requests are taking longer than expected Optimize resource allocation: Make informed decisions about scaling and resource distribution based on actual performance data Troubleshoot issues: Quickly diagnose performance problems by correlating metrics with specific bundle_ids

  • The endpoint returns metrics in a format compatible with monitoring tools and can be integrated with the provided example dashboards for real-time performance observability.

  • Prerequisites: To enable this endpoint, set http_metrics_enabled = True in the configuration file.
