Nagios Support Forum

Hello everybody,

I'm new to nagios. I'd like to know what are the best practices for JBoss EAP 7.x / Wildyfly monitoring these days.

I saw there's official check_jvm plugin for JBoss/Wildfly monitoring which is capable of monitoring rather "high level" metrics, such as: heap / non heap memory, cpu usage, uptime, class and thread count.

I'm additionally interessed in things like DB connection pools, Prepared Statement Cache Hit/Miss Count, Persistent Unit Metrics, Http Thread Pool, etc. What options are there to get these metrics monitored with nagios? Would jolokia be a viable way to expose metrics via rest interface? What nagios plugin to use for rest api calls towards jboss/jolokia rest interface?

Thank's a lot for your support!

I'm not familiar enough with Jolokia to know what all metrics are available, but there are a few JSON plugins available on the exchange as well as a wizard:

In addition to cdienger's post:

Did you see these guides?

Those are the only official guides we have at this point in time.

Here are the plugins for JBoss on the Exchange:

As we are not Java admins or run JBoss/Wildfly here you will need to work with your JBoss/Wildfly admins to test out the plugins and make sure that you have the connectivity/configuration required to check via those methods above.

Let us know if you have any questions or if we can clarify anything for you.

Thanks for your replies cdienger and saxx!

Yes I saw the guides, you've mentioned.

I'm now a step further to access JBoss EAP 7.x metrics with check_jmx plugin. As standard rmi doesn't work any longer, I had to change the connection URL to 'service:jmx:remote+http://localhost:9990' and had to add jboss-client.jar (from $JBOSS_HOME/bin/client folder) to the classpath of check_jmx.

Did you have any questions on it or is it working for your needs?
