Viewing Traces

Note: Traces are disabled by default. As a prerequisite, to enable the traces for an app, set the FLOGO_OTEL_TRACE variable to True from the Environment Control tab and Push Updates to apply your changes.
    Procedure
  1. Log in to Control Plane and navigate to the Data Plane details page.
  2. On the Applications tab, click a running Flogo app from the listed apps.

  3. Click the Traces tab.

The traces are collected via an OpenTelemetry collector. Tracing allows you to log information about an app's behavior during its execution.

Note: Traces depend upon observability configuration. For more information, see configure observability.

You can view detailed information through the Deep Dependency graph button or save results for further analysis using Download Results. Also, Flogo apps allow you to view tracing information using the Jaeger backend.

As the app travels through different services, each segment is recorded as a span. A span is a building block of a trace and represents work done with time intervals and associated metadata. All the spans of an app are combined into a single trace to give you a picture of an entire request.
