Jan Høydahl commented on SOLR-18147:
------------------------------------
Random thoughts from me:
* Many panels are ok and can be recreated
* Some panes doing aggregate data built by exporter may be recreated with
Grafana and PromQL foo
* Other panels originating from non-metrics source like queries, must be
dropped
* Some 9.x panels are very confusing and overloaded, and should be improved in
this new version. E.g. Java heap panel has graphs per solr node, but also
graphs for max, min, used, free etc. Better split this dimension to separate
panels, e.g. max, used, or with local selector in the panel for this dimension.
* Add number-of-segments graph
* Add a graph showing total index size on a node as percentage of free ram
(physical - heapMax) to judge whether the MMap cache ratio is sound
> Make a new Grafana dashboard for Solr 10.x

> URL: https://issues.apache.org/jira/browse/SOLR-18147
> Project: Solr
> Issue Type: New Feature
> Components: metrics
> Reporter: Jan Høydahl
> Assignee: Jan Høydahl
> Priority: Major
>
> Solr 10 removes support for the old /admin/metrics JSON format and also
> removes Prometheus Exporter. The {{/solr/admin/metrics}} endpoint will now
> return prometheus-format metrics, but with a completely new organization than
> before (OTEL native with labels etc). This renders the existing Grafana
> dashboard unusable, and we need a new.
> This task is to make a new dashbaord. Process
> # Solicit user experience / feedback about the old dashboard
> # Plan what the new dashboard should contain
> # Build and release the new dashboard
