do not enough $ARG$ for my service

[sacom01]

hi ben,
Thanks for your info. I can open the ticket, but our system is a high security system, offline system and you are unable to remote to the system from outside.
So is there another way to check this issue? do we need open the ticket as well?
Thanks.

Try doing this on the remote system:

Code: Select all

mkdir /home/nagios
chown nagios.nagios /home/nagios
chmod 0700 /home/nagios

Then restart the ncpa_listener and try again.

hi ben,
i tried but no luck, nothing changed.
only its process show when run the plugin.

Add this to your /etc/sudoers:

Code: Select all

nagios ALL=NOPASSWD: /bin/python3 /usr/local/ncpa/plugins/unix_check_OSprocess.py *

Make sure these are set in your ncpa.cfg:

Code: Select all

.py = python3 $plugin_name $plugin_args
run_with_sudo = unix_check_OSprocess.py

Restart the ncpa_listener service:

Code: Select all

systemctl restart ncpa_listener

Then test:

Code: Select all

/usr/local/nagios/libexec/check_ncpa.py -H X.X.X.X -P 5693 -t 'xxxxxx' -P 5693  -M 'plugins/unix_check_OSprocess.py' -q 'args=-wC 1 -cC 2  -wR 10 -cR 20 -wW 10 -cW 20 -wV 150 -cV 200'

That should do it. The sudo was required because the plugin is unable to get this info for the non-nagios services:

Code: Select all

		if(data["io_counters"] == None) :
			continue

hi ssax,
i tried but no luck.
it was not work from both nagios xi and remote server.

Try removing the /bin from the python3 in the sudoers, I had to do that with mine.

Set your run_with_sudo to this (it's not asking for a full path):

Code: Select all

run_with_sudo = unix_check_OSprocess.py

After both of those changes, restart the ncpa_listener service and test again.

I tried but not effect bro.

[ssax]

The run_with_sudo one shouldn't be in the /etc/sudoers.

Edit your /etc/sudoers, and add this:

Code: Select all

nagios ALL=NOPASSWD: /usr/bin/python3 /usr/local/ncpa/plugins/unix_check_OSprocess.py

Make sure this line is in your /usr/local/ncpa/etc/ncpa.cfg on the remote system under the [plugin directives] section:

Code: Select all

run_with_sudo = unix_check_OSprocess.py

Make sure you can sudo with it now:

Code: Select all

su - nagios
sudo /usr/bin/python3 /usr/local/ncpa/plugins/unix_check_OSprocess.py

Then restart the ncpa_listener service and test:
- Remove the | wc -l from the command so that I can see the output from the command

Code: Select all

systemctl restart ncpa_listener

hi,
i tried and able to execute the command in remote server now.
But still not work fine from nagios xi using ncpa. How to do run with sudo from nagios xi?
(wc -l just for shortly and count the result)

[ssax]

Is this in your ncpa.cfg on the remote system? (it needs to be under the [plugin directives], then restart the ncpa_listener service)

Code: Select all

run_with_sudo = unix_check_OSprocess.py
