DataStax OpsCenter is a visual management and monitoring solution for Apache Cassandra and DataStax Enterprise. OpsCenter provides architects, DBA’s, and operations staff with the capabilities to intelligently and proactively ensure their database clusters are running well and that administration tasks are simplified.
The DataStax agents are installed on the Real-time (Cassandra), Analytics (Hadoop), and Search (Solr) nodes. They use Java Management Extensions (JMX) to monitor and manage each node. Cassandra exposes a number of statistics and management operations through JMX. Using JMX, OpsCenter obtains metrics from a cluster and issues various node administration commands, such as flushing SSTables or doing a repair.
