This sample shows how to have SDK Prometheus metrics made available via HTTP.
To run, first see README.md for prerequisites. Then, run the following from this directory to start the worker:
uv run worker.py
This will start the worker and the metrics will be visible for this process at http://127.0.0.1:9000/metrics.
Then, in another terminal, run the following to execute a workflow:
uv run starter.py
After executing the workflow, the process will stay open so the metrics if this separate process can be accessed at http://127.0.0.1:9001/metrics.
