About OpsCenter

OpsCenter is a browser-based user interface for monitoring, administering, and configuring multiple clusters in a single centralized management console.

The OpsCenter 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.
