JMX monitoring of domain controlled servers

[thomasmosigfrey]

Hi

I use WildFly 8.2 in domain mode and have configured a set of server groups with their servers.

The wildfly jmx module is active and remote access successfully opened and accessed at the domain controller.

BUT:

Unfortunately I cannot open a JMX connection to the controlled servers for monitoring.

So I tried the classical JMX options as JVM parameters for these server JVMs (copied from the )

-Dcom.sun.management.jmxremote.rmi.port=3333

-Dcom.sun.management.jmxremote.port=3333

-Dcom.sun.management.jmxremote.ssl=false

-Dcom.sun.management.jmxremote.authenticate=false

The result is an error at the logging module and the wrong PermSize parameters.

To me it looks like a wrong composition of the start command built by the Host Controller.

Any idea to fix that? As I said: the goal is to retrieve monitoring data via JMX from the controlled hosts.

Cheers and many thanks in advance

Hi Craig

there are good news and it's a little embarrassing. Again thinking before acting helped :-).

As WIldfly starts to concentrate many of it's services at a few port numbers (http/https) the jmx queryies can simply be directed to these ports after the jmx subsystem is activated with the use-management-endpoint property set to false. I started to write a nagios plugin that can be used as a conveniant tool for JMX extracts as well. It will be found a sourceforge soon.

I hope this answer helps :-)

Cheers

Thomas
