null results with check_iseries.pl

[mariof]

Hi,

When I run the check_iseries.pl from the command line (as the nagios user), I get an expected result:

check_iseries OK - Current ASP used (%): 65.75 | total=564519763968b;; usage=371182460928b;;

When I run the same command within XI, i get a "null" result.

The script makes use of the Nagios::Plugin, but I was wondering is XI understands the output from the nagios_exit subroutine.

Any information will be helpful - my perl is very rusty.

Thanks in advance

Mario

Mario,

Can you post (place a screenshots) of your service and command definitions of this check in Nagios XI?

Hi,
here are the screen shots - nothing very remarkable, and the command line uses the same syntax.

I've also checked the nagios logs but all i can see is that the result is null. Is there a way of debugging this. using the -v option didn't help me.

mariof,

You can try adding "perl" in the path (in your command definition), so for example, instead of:

Code: Select all

$USER1$/check_iseries.pl -H ...

you will have:

Code: Select all

/usr/bin/perl $USER1$/check_iseries.pl -H ...

or

Code: Select all

/usr/bin/perl /usr/local/nagios/libexec/check_iseries.pl -H ...

Can you also post your actual check command that you use from the command line? You've shown only the check results in your first post.

Hi,

Here is the command with the community string removed (run as the nagios user from /usr/local/nagios/libexec):

./check_iseries.pl -H servername -c <string> -t 20 -o asp -w 80
check_iseries OK - Current ASP used (%): 65.77 | total=564519763968b;; usage=371295047680b;;

I also tried both your suggested changes to the command and it still didn't work. I think XI doesn't like the output from the command, but I can't tell for sure.

PS - i do use other snmp based perl scripts successfully. check_snmp_storage.pl and check_snmp_load.pl for example.

mariof,

We will do some more digging and will get back to you when/if we find a solution.

[mariof]

Thank you.

Not sure if this helps nor not, but neither check_snmp_load.pl or check_snmp_storage.pl use Nagios::Plugin

i fixed it!
i should have checked before, but i needed to change:
use lib "/usr/lib/nagios/plugins";
to
use lib "/usr/local/nagios/libexec";
