The JMX agent of WSO2 DAS monitors JMX attributes of a required JMX-enabled server (e.g. Carbon-based servers), and stores monitored data in WSO2 DAS. It uses the Thrift API of WSO2 DAS to send monitored data to DAS server. You can create a JMX monitoring profile to monitor a set of attributes from a single JMX server.
