Otis Gospodnetic commented on SOLR-4053:
----------------------------------------
I see. I'm guessing you have a relatively small number of servers, so watching
heap like this is OK. As clusters grow, using tools that provide both
aggregate views as well as individual server (and various metrics like the JVM
heap) views become a necessity.
> metrics - add statistics on searcher/cache warming
> --------------------------------------------------
>
> Key: SOLR-4053
> URL: https://issues.apache.org/jira/browse/SOLR-4053
> Project: Solr
> Issue Type: Improvement
> Affects Versions: 5.0
> Reporter: Shawn Heisey
> Priority: Minor
> Fix For: 4.1, 5.0
>
>
> One stat that I rely on is the amount of time that it takes to warm caches
> and an entire searcher, but unless you turn on INFO logging and write
> something to parse the logs, you can only see how long the last commit took
> to warm. I propose that we use the new metrics capability added in SOLR-1972
> to give us visibility into historical cache/searcher warming times.
> If I find some time in the near future, I will take a stab at creating a
> patch, but if someone else has an idea and time, don't wait around for me.
