Trace Workflows

This action fetches timing data about a GitHub Workflow and records it as a trace,

[ Backend                                                            ]
  [ test                                          ] [ lint         ]
    [ actions/checkout ] [ freckle/stack-action ]    [ hlint ]

Work In Progress

So far we have a Haskell executable that fetches this data, builds up the spans and emits them using the OpenTelemetry SDK. This requires an otel-collector side-car (or other service) to receive and process the trace data, for example sending it to Datadog.

The docker-compose.yml in this repository can run such a collector. This container as well as the action itself, make use of .env. See .env.example.

Next Steps

In order to make this work we'd need to:

1. Either rewrite in TypeScript (see pb/ts branch), or dockerize for use as a Docker-based action
2. Figure out how to best run a collector side-car on Actions and document that
