Nagios check_mk with plugins
I'm working a company that has a Nagios monitoring server that was set up ages ago and there's no documents.
It uses Check_MK and it seems it was installed using OMD.
We want to install the following plugin to monitor our RDS servers:
I've tried to manually configure the files with Nagios command and the file with Host and Services but doesn't seem to work at all.
Anyone knows how to configure the CheckMK to use a plugin (like a script or something) for a host? Or to install those other plugins to be acceptable by CheckMK.
