      Description

      The statistics that can currently be gathered via JMX tend to be core-specific, making monitoring "how is the Solr node doing" harder than it needs to be. This JIRA is about exploring what it would take for instance-wide statistics to be JMX-enabled.

      I'm imagining cumulative stats like:
      > How many Solr<->Solr communications errors have there been?
      > How many Solr<->ZK communication errors have there been
      > How many full synchronizations have happened across all replicas?
      > Operations people, fill in your favorite health monitoring bit here.

      What do people think? Is JMX even the right thing? We have an admin end-point for gathering information, but that's not as "operations friendly".

      I'm open to any suggestions for how/where to implement this, whether there are any huge "gotchas", bottleneck concerns, etc.
