Nagios Support Forum

Hello,

New to nagios core and need some help trying to install/configure the check_ncpa.py script.

I am getting the error below :

“ Warning: Return code of 13 for check of service 'Process Count' on host 'mds-rocky-01' was out of bounds. “

I tried changing the ownership and permissions of the file.

sudo chown nagios:nagios /usr/lib64/nagios/plugins/check_ncpa.py
sudo chmod 750 /usr/lib64/nagios/plugins/check_ncpa.py

I am also able to run the check_ncpa.py script from the CLI as the nagios user.

Can someone point me in the right direction ?

Thanks, mp

Hi @nagios-mikep97,

What version of Nagios Core and Nagios Plugins do you have installed?

Hello @nagios-mikep97,

It seems that there have been several issues that have caused a return code 13 issue. One was the permissions issue, but another was a windows line ending issue. If you could try checking your check_ncpa.py version with the -V option and use the -v option when running your check to get verbose output, we can help get to the bottom of this more easily.

Thanks for the help

Nagios Core Version = 4.4.14
check_ncpa.py version = 1.2.5

*My first NCPA client is a rocky_9 host. a

Below is the output froming check_ncpa.py as nagios user.

@nagios-mikep97

It seems your issue lies with the check 'Process Count'. What are the command and output (with -v) for this particular check?

Bbahn,

Thanks. I am getting the same error on all of the NCPA checks. Below is the output of the proccess count request run as the nagios user.
