Overview

This chart deploys a Prometheus Exporter for Prefect Server, providing relevant metrics from your deployed Prefect Server instance. Shoutout to @ialejandro for the original work on this chart!

Installing the Chart

Prerequisites

1. Add the Prefect Helm repository to your Helm client:

   helm repo add prefect https://prefecthq.github.io/prefect-helm
   helm repo update

3. Verify the deployment

   Check the status of your Prometheus Prefect Exporter deployment:

   kubectl get pods -n prefect
   
   NAME                                  READY   STATUS    RESTARTS       AGE
