Resolves #55755

Now, we see:

It's a little complicated with logstash monitoring documents, due to the nested fields, so you'll notice some of that in the code.

Testing

  • Setup logstash monitoring and ensure logstash is running with multiple pipelines
  • Verify the events emitted chart on the overview page is indeed the sum of the events emitted metrics on the listing page
