Subject [jira] [Commented] (SOLR-13979) Expose separate metrics for distributed and non-distributed requests
Date Wed, 04 Dec 2019 04:36:00 GMT

    [ https://issues.apache.org/jira/browse/SOLR-13979?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16987519#comment-16987519
] 

Shawn Heisey commented on SOLR-13979:
-------------------------------------

My old solution for this, on systems NOT running in cloud mode, was to define an aggregation
core which had the shards parameter defined in solrconfig.xml.  Relevant stats were found
by looking at the /search handler on that core.  I also defined a special handler on every
core which was used by ping health checks and other miscellaneous automated uses so that those
requests would not impact stats for real queries.

Does SolrCloud keep separate stats for requests sent to the collection name rather than a
specific shard/core?  If not, I think it should.  I have no idea how to implement such a
thing.

> Currently we expose metrics such as count, rate and latency on a per handler level however
for search requests there is no distinction made for distrib vs non-distrib requests. This
means that there is no way to find the count, rate or latency of only user-sent queries.
> I propose that we expose distrib vs non-distrib metrics separately.
