The first step is to test the plugin directly on your host, this will remove NRPE from being a problem.

Please show us the command used to test the plugin and the output from the plugin.

[dheerushops]

[root@nagioshost ~]# /usr/local/nagios/libexec/check_nrpe -H localhost -c check_hdbnameserver.py
UNKNOWN - is .We can not identify process status
[root@nagioshost ~]#

[root@nagioshost ~]# /usr/local/nagios/libexec/check_nrpe -H localhost -c check_hdbnameserver.py
UNKNOWN - is .We can not identify process status
[root@nagioshost ~]#

can you please take nrpe out of the equation, and run the check_hdbnameserver.py script with the needed parameters? then, let us know the result.

Thanks @tacolover101!

[dheerushops]

[root@nagioshost ~]# /usr/local/nagios/libexec/ -H localhost -c check_hdbnameserver.py
-bash: /usr/local/nagios/libexec/: Is a directory

What was being asked is can you run check_hdbnameserver.py on the remote server to see what the response is.

[dheerushops]

[root@nagioshost libexec]# ls -lh check_hdbnameserver.py
-rwxrwxr-x 1 nagios nagios 1.4K Jan 9 08:19 check_hdbnameserver.py
[root@nagioshost libexec]# pwd
/usr/local/nagios/libexec
[root@nagioshost libexec]# check_hdbnameserver.py
-bash: check_hdbnameserver.py: command not found
[root@nagioshost libexec]#

I think you meant to run

Code: Select all

./check_hdbnameserver.py

You need to be able to get the plugin to work correctly (and giving you expected output) on the remote server before trying to make it work through NRPE
