The workflow file looks fine to me. I'm not sure what this container is meant to do though.

It builds the container in #117461. I definitely could've made this a bit more clear in the commit description. Sorry about that.

It essentially packages the script in that PR which every five minutes grabs information about the workflows that have completed since the previous check and dumps the data into Grafana for visualization/alerting.

Sorry thought I had approved this one earlier.
