Charting spool alert metrics

Cloudera Manager supports chart visualization of spool directory disk usage metrics.

Single-level metrics for collecting the disk usage of Solr and Hdfs Ranger plugin spool directories are registered in Cloudera Manager, using the following disk usage metric names:

Solr: ranger_plugin_solr_spool_directory_size
HDFS: ranger_plugin_hdfs_spool_directory_size

You can chart disk usage of Solr and HDFS spool directory size as a time-series, using Cloudera Manager > Chart Builder.

For example, to chart the disk usage for the Solr spool directory defined for Kafka Broker, use the folllowing query syntax:

SELECT ranger_plugin_solr_spool_directory_size WHERE roleType = KAFKA_BROKER, as shown in
