Hi Team,
We have around 200 collections in one solr instance and whenever this metrics
api is called from solr admin page, it is leading to timeout error. This error
leads to "Solr connection lost" error intermittently.
We don't see any way to increase the timeAllowed or disable it completely.
Please suggest some way to resolve this error.

> Following on from a discussion on the mailing list:
> http://search-lucene.com/m/IO0EI1qdyJF1/codahale&subj=Solr+metrics+in+Codahale+metrics+and+Graphite+
> It would be good to make Solr play more nicely with existing devops
> monitoring systems, such as Graphite or Ganglia. Stats monitoring at the
> moment is poll-only, either via JMX or through the admin stats page. I'd
> like to refactor things a bit to make this more pluggable.
> This patch is a start. It adds a new interface, InstrumentedBean, which
> extends SolrInfoMBean to return a
> [[Metrics|http://metrics.codahale.com/manual/core/]] MetricRegistry, and a
> couple of MetricReporters (which basically just duplicate the JMX and admin
> page reporting that's there at the moment, but which should be more
> extensible). The patch includes a change to RequestHandlerBase showing how
> this could work. The idea would be to eventually replace the getStatistics()
> call on SolrInfoMBean with this instead.
> The next step would be to allow more MetricReporters to be defined in
> solrconfig.xml. The Metrics library comes with ganglia and graphite
> reporting modules, and we can add contrib plugins for both of those.
> There's some more general cleanup that could be done around SolrInfoMBean
> (we've got two plugin handlers at /mbeans and /plugins that basically do the
> same thing, and the beans themselves have some weirdly inconsistent data on
> them - getVersion() returns different things for different impls, and
> getSource() seems pretty useless), but maybe that's for another issue.
