How to use Jconsole to monitor Cassandra in Cassandra

We now have a three-node Cassandra cluster on 192.168.129.34, 192.168.129.35, 192.168.129.39, because we have 7199 ports on each node (JMX monitor Port), So we can use Jconsole to detect the state of these nodes.

Open the Jconsole under%java_home%/bin, enter 192.168.129.34:7199 in the remote connection, and then click Connect:

So you can go to the Jconsole interface:

We can see this node's statistics in the Overview tab page:

Because JMX can provide a visual interface for monitoring managed beans (specifically to connect to Mbean Server with Htmladapter), we can see several information about Cassandra's Mbean here:

For example, from this picture we see 192.168.129.34 and 192.168.129.35 still alive, but 192.168.129.39 has fallen down.
