Nagios Support Forum

If I deactivate the service, why is Nagios still trying to run checks? If it continues to run checks, is there a way to prevent it besides deleting the monitor?

[1472790816] Unable to run check for service 'Windows Memory Usage' on host 'X'
[1472790818] Unable to run check for service 'Windows CPU Usage' on host 'X'
[1472790818] Unable to run check for service 'Windows Memory Usage' on host 'X'

After deactivating those checks in the Core Config Manager, did you save the changes and Apply the Configuration?
Also, there could be duplicate nagios processes running on your system which could cause the issue you are seeing.
To fix that, run the following as root and see if those checks stop running.

I did a check again on the log, because apply configuration has been been done a few time since opening this request. I am no longer seeing the problem. This can be closed.
