Nagios Support Forum

I run check_iferrors_percent from the command line as root and it executes successfully. I create a service to execute the exact same command and get a return code 255 out of bounds error. I ran chmod 777 on check_iferrors_percent but I still get the same error.

Hi hollanro,
Could you please making sure that "check_iferrors_percent" is added to the "nrpe.cfg" (below) on both Nagios XI and nrpe (remote)?

Example of command defined in "/usr/local/nagios/etc/nrpe.cfg": Also, please make sure that nrpe agent is running. Best Regards,
Vinh

This is not using an npre agent, it's using snmp to a network switch.

Hi hollanro,
Can you please post the service and commands settings? .... picture would helps.
I need to know how your command is defined and how it is being called in XI.

Also, can I also see the exact error? ..... any helpful details follows the "255 out of bounds".

Since you said that you ran "check_iferrors_percent" from the command line as root and was successful.
Can I also see the exact command for that as well.

Regards,
Vinh

Hi hollanro,
Since you were able to run this command manually on the command line, I'm guessing that you could try adding a single quote to your ARGV or break them down to smaller value ..... like using "-v $ARG1$ -s $ARG2$ -T $ARG4$ -t $ARGV4$" for example.

To do that, you will have to change the definition of the command inside the "commands.cfg" file first.

Here's an example: Can you please show me (upload) the contents inside the service config file for this service? Also, can you please show me (upload) the "commands.cfg" file? Regards,
Vinh

I was able to resolve...i was running the command from the command line using root not realizing that the check stores data in a temp file. Once i moved it to Nagios to run as a service the check did not have access to the temp data. I just deleted the temp data files from the command line run and reran the Nagios check and everything worked. Thanks for all of your help Vinh!

Hi hollanro,
Great!! .... I will lock/close the post/ticket ...

Vinh
