Monitor the BlockCache

Cloudera Manager provides metrics to monitor the performance of the BlockCache, to assist you in tuning your configuration.

You can view further detail and graphs using the RegionServer UI. To access the RegionServer UI in Cloudera Manager, go to the Cloudera Manager page for the host, click the RegionServer process, and click HBase RegionServer Web UI.

If you do not use Cloudera Manager, access the BlockCache reports at http://regionServer_host:22102/rs-status#memoryStats, replacing regionServer_host with the hostname or IP address of your RegionServer.
