I am trying to move from Nagios to OMD, however, I have a Nagios plugin which I really need (phpfpm) but I am unable to add the plugin to check_mk.
On the check_mk website says that you should use MRPE however, when I try to run the "cmk" command my OS is complaining that the command doesn't exist.
What you guys are suggesting I could use to run Nagios plugins from OMD?
I am running CentOS with OMD 1.20 installed.
I guess you need to configure /etc/check_mk/mrpe.cfg on the host you want to monitor like described in the CheckMK documentation. You also need to put your Nagios Plugins on the host you want to monitor.
When you finished that you can run cmk -I --checks=mrpe host-to-monitor from OMD. To get to the OMD console of your CheckMK instance use su - name-of-your-omd-instance
The files created by OMD are created by Check_mk, in the command file itself, they will clearly say that below commands are generated by the Check_mk, Please don't edit those files.
When you use Nagios alone as a monitoring system, you need to add the host and services from command line.
In case if you are about to go with Check_mk then the host and services can be added in GUI itself.
Create a monitor using command:
sudo omd create MONITER_NAME
sudo omd start monitor
Then in your browser IP_ADDRESS/MONITER_NAME
Default Username: omdadmin Default Password: omd
If you add the host in the check_mk, it will be reflected in Nagios also.
Please let me know if you're stuck anywhere after this steps.
