There are at least five different jobs in graphana related to the job queue, and only one of them is working.
Apparently, https://grafana.wikimedia.org/d/LSeAShkGz/jobqueue?orgId=1 is the main one? But I'm not sure about that.
This confuses volunteers investigating jobqueue issues like T275437: Jobs are not getting executed or executed really slowly.
