title: Grafana: Add annotation on multiple panels at once
body: <p>I would like to add an annotation on <strong>all panels</strong> (graphs) in the Grafana dashboard.
  I could add annotations manually one-by-one on all panels -- but I hope there is a better way how to do it although I didn't find any information <a href="https://grafana.com/docs/grafana/latest/reference/annotations/" rel="noreferrer">in the official documentation</a>.</p>
  
  <p>I suppose I can write a script using Grafana API to create annotation on all panels in dashboard; however this seems like a complicated workaround more than an actual solution.</p>
  
  <p>Do you know how to easily add annotations on all graphs at once?</p>
