The Master Agent

The master agent is deployed in the Common Agent Container on a separate machine as part of the Monitoring Console installation. The master agent is configured with the name or address of all nodes so that it can aggregate the monitored objects from all of the node agents. The master agent is a JMX manager, and it communicates with the node agents through the JMX connector.

The following diagram represents a master agent connected to two nodes. The Monitoring Console connects to the master agent to display the three components on each node. If you use SNMP for monitoring, you must connect to each node separately because the master agent does not aggregate SNMP attributes. The master agent is designed for use with the Monitoring Console only and cannot be accessed by other monitoring applications.
