Monitoring cometd client about cometd HOT 1 OPEN

BayeuxClient is currently not exposed for monitoring although its components can be exposed.

You can see an example of exposing BayeuxClient starting from this line:
https://github.com/cometd/cometd/blob/7.0.9/cometd-java/cometd-java-benchmark/cometd-java-benchmark-client/src/main/java/org/cometd/benchmark/client/CometDLoadClient.java#L352

Right now it exposes some isXYZ() methods related to its internal state.
You can add a TransportListener to be notified of transport events (messages sent or received).

Health tracking can be done by sending a special health message from the client to the server, and see if you get a reply from the server (but it requires the server to understand and reply to those messages).

For /meta/ messages, you can easily register a listener and be notified, for example, of /meta/connect messages and derive from there their rate, when the last was sent/received, its content, etc.

There is nothing pre-made, but depending on what exactly you need, you should be able to setup what you want.
