Want to try Hazelcast Platform?

We’ve combined the in-memory storage of IMDG with the stream processing power of Jet to bring you the all new Hazelcast Platform.

JMX API per Member

4.2 4.1 4.0 3.12 3.11 3.10 3.9 3.8 3.7 3.6 3.5

Hazelcast members expose various management beans which include statistics about distributed data structures and the states of Hazelcast member internals.

The metrics are local to the members, i.e., they do not reflect cluster wide values.

You can find the JMX API definition below with descriptions and the API methods in parenthesis.
