Shalin Shekhar Mangar updated SOLR-256:
---------------------------------------
Attachment: SOLR-256.patch
*Changes*
* Renamed JmxManager to JmxMonitoredMap which extends a ConcurrentHashMap and
overrides put, remove and clear methods
* The JmxMonitoredMap is used to hold the infoRegistry (String->SolrInfoMBean)
so that registration and unregistration is done automatically (which takes care
of dynamic registration of request handlers, lazy loading, new
SolrIndexSearchers etc.)
* The SolrIndexSearcher is added with the name "searcher" to the map so that
the name of the MBean doesn't change which helps setup monitoring
* Instead of removing SolrIndexSearcher from the registry, it is simply
replaced when SolrIndexSearcher#register method is called. This makes sure that
the searcher registered with JMX is the current searcher (with a small margin
of error)
* Added two tests
** TestJmxMonitoredMap passes a service url syntax to JmxMonitoredMap and uses
a mocked SolrInfoMBean to test the put, remove and clear methods. Note that
this test uses a hard-coded port number -- unavailability of this port will
fail the test.
** TestJmxIntegration uses the AbstractSolrTestCase with the platform
MBeanServer to test availability of Solr MBeans and tests for its updation by
adding a document.

> This patch adds JMX capability to get statistics from all the SolrInfoMBean.
> The implementation is done such a way to minimize code changes.
> In SolrInfoRegistry, I have overloaded Map's put and remove methods to
> register and unregister SolrInfoMBean in MBeanServer.
> Later on, I am planning to use register and unregister methods in
> SolrInfoRegistry and removing getRegistry() method (Hiding the map instance
> to other classes)
