Description

Computing JVM metrics for threads can be expensive, and we should provide option to users to avoid doing so on every call to the metrics API (group=jvm).

solr.xml:

<solr>
<metrics enabled=true>
  <caching>
    <int name="threadsIntervalSeconds">2</int>
  </caching>
..
</metrics>
</solr>
