[jira] [Commented] (SOLR-15007) Aggregate core handler=/select and /update metrics at the node level metric too
[ https://issues.apache.org/jira/browse/SOLR-15007?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17568720#comment-17568720 ]
Justin Sweeney commented on SOLR-15007:
---------------------------------------
We encountered this same issue at FullStory since we have many cores per node and wanted better visibility into aggregate metrics per node. I have attached a PR for how we resolved this. I believe this lines up pretty well with the approach outlined by [~dsmiley] above. The approach taken in the PR attached allows for configuring node level metrics on a per request handler basis. It would also be possible to enable it automatically for all request handlers instead if that is preferable for the community.

> Components: metrics
> Affects Versions: 9.0

> At my company, we anticipate huge number of cores and would like to report aggregated view at the node level instead of the core level that will grow exponentially.
> Right now, we're aggregating all of the solr.cores metrics to compute per-cluster dashboards.
> But given that there are many admin handlers already reporting metrics at the node level, I wonder if we could aggregate _/update_, _/select_ and all the other handler counters in solr and expose them at the solr.node level too.
> It would requires (a lot) less data to transport, store and aggregate later, while still giving access to per core metrics.
