Nagios Support Forum

I recently added an Ubuntu server to my NagiosXI. I followed the standard procedure that has always worked for me in the past. This server is giving me an error on the CPU check, see attachment, but all the other services are checking properly. Please assist.

Thanks.

Did you run through this common solutions document?

Usually this is because Ubuntu is using dash instead of bash. Check out the "The wrong interpreter is used when running the remote plugin" section and see if that offers any help.
