with NRPE we are able to do indirect checks as explained in:
https://assets.nagios.com/downloads/nag ... e/NRPE.pdf
2. EXAMPLE USES b) Indirect Checks

Is there a way to do the same with NCPA?

I'm trying to follow the same logic with NCPA, but I seem to be stuck on the "" placements, I have tried different combinations but keep keeping errors like:

Code: Select all

Belay my last, I found the issue. The systems I am testing are still using python2, I had to edit the ncpa.cfg on the middle server:
[plugin directives]
.py = python3 $plugin_name $plugin_args --> .py = python $plugin_name $plugin_args

And then the remote checks started working.

this thread can be locked. Thanks.
