Hoss Man commented on SOLR-5648:
--------------------------------
1) I'm not sure i really understand what this adds -- isn't every registered
searcher (which should include every open searcher if there are more then one)
already listed in the infoRegistry (so it's stats are surfaced in /admin/mbeans
and via JMX) ?
2) having a searchLock in getStatistics scares me ... seems like a recipe for
all sorts of inexplicable performance oddities on opening new searchers just
because a monitoring agent (or 10) polls all stats every second.
> SolrCore#getStatistics() should nest open searchers' stats

> {{SolrIndexSearcher}} leaks are a notable cause of garbage collection issues
> in codebases with custom components.
> So it is useful to be able to access monitoring information about what
> searchers are currently open, and in turn access their stats e.g.
> {{openedAt}}.
> This can be nested via {{SolrCore#getStatistics()}} which has a
> {{_searchers}} collection of all open searchers.
