Python module to emit prefect2 metrics that are scraped by prometheus
Merged PR in Prometheus

Metrics naming convention

Set prefect2 url in values, then:
helm3 upgrade prefect2 . --install --values values.yaml --namespace prefect2

Set env vars:

bash
export PREFECT_UI_API_URL=https://prefect2/api
export EXPORTER_PORT=30042
export EXPORTER_VERSION=1.0.0

Create new Dockerfile and use my as BASE, e.g.:

Dockerfile
FROM pathfinder177/prefect2-prometheus-exporter:tag
ENV PREFECT_UI_API_URL 
ENV EXPORTER_PORT 30042
ENV EXPORTER_VERSION 1.0.0 https://prefect2/api
CMD ["python3", "exporter.py"]

It exports on port 30042 by default:
