Using metrics MBeans 

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

DataStax Enterprise provides commit, merge, query, and update metrics MBeans for troubleshooting and 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

<core> is the name of the Solr core referenced by the metric.

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