             Summary: We should distinguish between top-level queries and sub-queries when reporting stats
                 Key: SOLR-8301
                 URL: https://issues.apache.org/jira/browse/SOLR-8301
             Project: Solr
          Issue Type: Improvement
    Affects Versions: 5.4, Trunk
            Reporter: Erick Erickson


It looks like we look at all query times when reporting plugins/stats. This includes sub-queries in SolrCloud (i.e. distrib=false).

This doesn't really give a true picture of what the _user_ sees, i.e. it doesn't really reflect "the laggard problem".

To diagnose a cluster's performance, it seems like it would be useful to aggregate perf stats in two groups at least, the top level (i.e. distrib != false) and distrib=true.

Or perhaps even three, the aggregator times, the distrib=false grouping and actually getting the stored data from the docs to return the client.

This is always available in the logs, but being able to monitor them with JMX seems useful.
