Hi,

You will need to monitor through JMX via this method for now:

Thanks for your answer. I have this error

In wildfly 14, jmx use "service:jmx:http-remoting-jmx", I think so..

[jomann]

You're running the plugin locally on the java server? It seems like it's having trouble connecting to service:jmx:rmi:///jndi/rmi://localhost:9990/jmxrmi, is there a way to verify that your java is running and port 9990 is accepting requests?

[eSailVite]

Hi,

The 9990 port is open.

look at the imagen

Regards

[scottwilkerson]

Is the firewall open on that port as well?

Code: Select all

iptables -L -n

[eSailVite]

Hi,
The port is open as well.

[scottwilkerson]

You have ./check_jmx installed on the remote machine right? Not the Nagios server right?

[eSailVite]

Hi,

Yes... I installed jmx on the remote server.

[scottwilkerson]

In doing some googling on this error it is possible that rmi port isn't the same as the jmx port

See answer I found here
