Nagios Support Forum

Hi, I am getting this error

**ePN /usr/local/nagios/libexec/check_nwc_health: plugin did not call exit()
**ePN /usr/local/nagios/libexec/check_nwc_health: "Use of uninitialized value $opt in string eq at /usr/share/perl5/Getopt/Long.pm line 487,".

what i did was update check_nwc_health on my nagios and worker server.

nagios running on rhel6
and worker running on rhel7
it was working until i update the plugin.


on master :
[root@master~]# find / -iname long.pm
/usr/share/perl5/Getopt/Long.pm

on worker
[root@worker~]# find / -iname long.pm
/usr/share/perl5/vendor_perl/Getopt/Long.pm

Kindly assist. thanks

"check_nwc_health" is not one of our official nagios plugins. It's a 3rd party plugin. We will try to help but it may take some time as we are not familiar with the plugin.

Can you provide us with a download link to "check_nwc_health"? What is the version that you upgraded from/to? We will try to recreate the issue in house.

BTW, have you tried contacting the owner of the plugin? Thank you!

hi,
i upgrade from check_nwc_health-4.6.1 to check_nwc_health-6.3.0.6.
Kindly let me know if you need more information.
I have just contacted the owner and waiting his reply.

Thank you

Hi ,
update:
I have move all the network checks into localhostgroup at mod_gearman, and now all the checks are back to normal.
So most probably when the checks pass to the worker they cant check it.However if i run the command manually on the worker, they are able to check.

Thanks,

Thanks for reporting back your findings.
If you want to run that plugin on the remote host using the gearman worker, you would have to install all of the requirements for that plugin on that server.

The same plugin is installed on the worker, and able to check and get result if I manually type command in the terminal


Thanks

Can you run the following command on both boxes - the server and worker(s), and show the output?

Hi, Thanks for your reply.

Kindly refer to the information

server
grep use_embedded_perl_implicitly /etc/mod_gearman2/worker.conf
use_embedded_perl_implicitly=off

worker
grep use_embedded_perl_implicitly /etc/mod_gearman2/worker.conf
use_embedded_perl_implicitly=off

Thanks

Can you login to your remote Gearman worker and run the plugin as the nagios user and post the output by running the following commands? Can you post the worker.conf file from the remote gearman server?
If you run the check from the Nagios server using Mod Gearman, what error are you getting?
