We have Check_MK monitoring installed.
The Check_mk agent installs automatically when I add a host to the Check_MK GUI.
Because of this there is no main.mk installed /etc/check_mk on the added hosts.
Question: Do I have to manually add this??
Also, I would like to monitor a wildfly server. The Jolokia war file is installed on the host and does give an output through a browser but how do I then add a plugin such as jar_signature or jolokia_metrics.gc?
I see very little documentation on the Check_MK website. Any help would be very much appreciated.
Yes, thanks, that was it.
I was incorrectly told that it would be all automatically done from check_mk server. Only the initial install was done but any plugins and baked agent were not. Once I install plugins in usr/lib/check_mk/plugins/ such as jolokia does it all come together. I don't know yet how to use the /local directory yet.
Thanks for your input.
I don't think main.mk is needed on monitored hosts. It is only needed on the Nagios host.
On the monitored hosts, we need two things:
check_mk_agent (scheduled through xinetd)
check_mk local check scripts under /usr/lib/check_mk_agent/local directory
check_mk_agent performs the standard (built in) checks and then calls the scripts under /usr/lib/check_mk_agent/local one by one, in alphabetical order. Nagios invokes check_mk_agent by talking to xinetd (which usually listens on port 6557) which in turn invokes check_mk_agent.
