Export Job Telemetry

This GitHub Action is designed to export telemetry data for a GitHub Actions job, including resource attributes and timing information, using OpenTelemetry. To minimise API calls to the GitHub API and to ensure deterministic trace and span IDs, instrument your workflow with https://github.com/krzko/setup-telemetry.

This action is intended to be used in conjunction with the OpenTelemetry Collector GitHub Actions Receiver. This receiver processes GitHub Actions webhook events to observe workflows and jobs, converting them into trace telemetry for detailed observability.

Features

• Export trace data in OpenTelemetry format.
• Capture and report the start and end times of the GitHub Actions job.
• Include custom resource attributes for enhanced observability.
• Utilises deterministic Trace and Span IDs to align with the OpenTelemetry Collector GitHub Actions Receiver.

GitHub Actions Receiver

The GitHub Actions Receiver processes GitHub Actions webhook events to observe workflows and jobs. It handles workflow_job and workflow_run event payloads, transforming them into trace telemetry. This allows the observation of workflow execution times, success, and failure rates. If a secret is configured (recommended), it validates the payload ensuring data integrity before processing.

For more details on the receiver, see the GitHub issue: OpenTelemetry Collector Contrib #27460.

Usage

To use this action in your GitHub Actions workflow, add a step that references this action in your .github/workflows/ YAML file.

Here is a basic example of how to use this action:

Outputs

This action does not set any outputs directly, but it sends telemetry data to the specified OpenTelemetry collector endpoint.
