OpsCenter architecture overview
Basic architecture diagram and brief explanation.
The DataStax agents are installed by the Cassandra and DataStax Enterprise installers. The agents 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.
