Using metrics MBeans 

To troubleshoot, tune performance, and resolve consistency issues, use commit, merge, query, update, and index pool metrics MBeans.

DataStax Enterprise provides commit, merge, query, update, and index pool metrics MBeans for troubleshooting, and for tuning performance and consistency issues.

The following paths identify the MBeans:

type=search,index=core,name=CommitMetrics
type=search,index=core,name=MergeMetrics
type=search,index=core,name=QueryMetrics
type=search,index=core,name=UpdateMetrics
type=search,index=core,name=IndexPool

where core is the name of the Solr core that is referenced by the metrics.

For example, the following figure shows the com.datastax.bdp merge metrics MBean in JConsole. The demo.solr core under search is expanded.
