: Hi Solr Users, : : Is there a metric endpoint or a debug/explain type query param that : returns average time spent in aggregating the search results from shards?
Sort of? Metrics like "QUERY./select.distrib.requestTimes" tell you the stats on handling a "distributed" request -- which is when a core is responsible to sending out "per-shard" requests and merging the responses. But it doesn't *only* include the "time spent in aggregating the search results from shards" ... it also includes the time spent determining which requests to send to which shards, and waiting for the responses to those (frequently concurrent) requests" -Hoss http://www.lucidworks.com/
