Trace Temporal workflows with OpenTelemetry

interceptors-opentelemetryskillsetup L2★0

What it does

Trace Temporal.io Workflow and Activity execution with OpenTelemetry

Best for

Observing Temporal Workflow execution timing and step dependencies by emitting structured traces to OpenTelemetry-compatible backends (Jaeger, Datadog, etc.).

Inputs

· Temporal SDK Workflow/Activity code
· OpenTelemetry exporter configuration

Outputs

· Tracing spans (workflow start/end, activity execution, step timing)
· OpenTelemetry-compatible trace data

Requires

· @temporalio/interceptors-opentelemetry
· OpenTelemetry exporter (e.g., Jaeger, Datadog)
· Temporal TypeScript SDK

Preconditions

· Temporal Workflow defined
· @temporalio/interceptors-opentelemetry installed
· OpenTelemetry exporter configured

Failure modes

· Interceptor not wired into SDK client
· OpenTelemetry exporter unreachable
· Activity/Workflow code does not emit expected spans

Trust signals

· Temporal SDK interceptor integration documented
· Activity and Workflow lifecycle tracing explicit
· OpenTelemetry exporter agnostic design
