Troubleshoot service endpoints

The Service Inspector in Observe APM provides powerful tools to understand and troubleshoot the performance of your service endpoints, whether they involve HTTP, RPC, or message-based protocols. By leveraging detailed telemetry data, you can quickly pinpoint and resolve performance issues, identify bottlenecks, and ensure the reliability of your endpoints.

You can sort the list of endpoints for a service by total latency across all requests to quickly identify the most impacting endpoints, or alternatively, select a specific endpoint directly from the dropdown. Once an endpoint is selected, you can inspect its RED (Rate, Error, Duration) metrics, view errors and exceptions, correlate performance with recent deploys, drill down into traces, and analyze its behavior in detail. The Service Inspector also allows you to toggle between synchronous (HTTP/RPC) and asynchronous (message-based) endpoints.

 

Terminology

The “Endpoint” terminology in Observe has equivalents in other APM products:

Observe	Datadog	New Relic	AppDynamics / Dynatrace
Endpoint	Resource	Transaction	Business Transaction

Toggling between HTTP/RPC endpoints and message-based endpoints in Observe also has equivalents in other APM products:

Observe	Datadog	New Relic
Endpoint dropdown	Operation dropdown	Web/non-web transaction dropdown

Underlying OpenTelemetry data used to detect endpoints

• Spans of type SERVER are used to detect HTTP/RPC endpoints. The endpoint name in Observe is the span name.

• Spans of type CONSUMER are used to detect message-based endpoints. The endpoint name in Observe is the span name.
