Monitoring DSE Search 

Information about metrics MBeans for DSE Search.

DataStax Enterprise exposes a number of statistics and management operations via Java Management Extensions (JMX). JMX is a Java technology that supplies tools for managing and monitoring Java applications and services. Any statistic or operation that a Java application has exposed as an MBean can then be monitored or manipulated using JMX.

Metrics MBeans are used for troubleshooting, tuning performance and consistency issues.

Use the IndexPool JMX MBean to view the progress of indexing tasks.

The StallMetrics is exposed through the metrics registry com.datastax.bdp.metrics.

The following paths identify the MBeans:

type=search,index=search_index,name=CommitMetrics
type=search,index=search_index,name=MergeMetrics
type=search,index=search_index,name=QueryMetrics
type=search,index=search_index,name=UpdateMetrics
type=search,index=search_index,name=IndexPool
type=search,index=search_index,name=StallMetrics

where search_index is the name of the search index that is referenced by the metrics.

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