Nagios Server- Remote Plugin "Incorrect Values"

[Shivaramakrishnan]

Hello,
I just added a service check on the remote client running nrpe.The service check is written in bash and gives the right output when appropriate values are passed to it,have the necessary servers to access and the required ports open.

Sample Output from the command line on the remote client:
/usr/lib/nagios/plugins/check_arcconf.sh -w 50 -c 70
RAID WARNING, 0 numParityErrors, 0 hwErrors, 68 mediumErrors

nrpe_local.cfg file of the remote client
command[check_arcconf]=/usr/lib/nagios/plugins/check_arcconf.sh -w $ARG1$ -c $ARG2$

But when I try to access the same command from the Nagios server,I am getting Null Values and the Output is different.

Sample Output from the command line on the Nagios Server
/usr/lib/nagios/plugins/check_nrpe -H IP_Address
RAID OK, numParityErrors, hwErrors, mediumErrors

Sample Service check Definition:
define service {
use adaptech-raid-checks
hosts xyz
service_description ADAPTECH Raid Check
check_command check_nrpe_1arg!check_arcconf!50!70
}

I have searched many links but no success yet.Can anyone please let me know what I am missing or what am I doing wrong?
Please let me know as soon as possible.

Thanks in advance!!!!

When you run it from the command line for testing, make sure it works when run as the nagios user. Many people seem to forget that Nagios checks do not run with root permissions.

Code: Select all

su nagios -s /bin/bash -c "/usr/lib/nagios/plugins/check_arcconf.sh -w 50 -c 70"

[Shivaramakrishnan]

Are you talking to run the command as user "nagios" on the server or on the client?

[agriffin]

I'm talking about the client in this case, but the same advice applies whenever you're testing plugins, whether it's on the Nagios server or a remote client.

[Shivaramakrishnan]

And what needs to be done in order to run the script to show the output as shown when run by root.

Hi Agriffin
As root I am getting
[root@dbs01-ple03 ~]# /usr/lib/nagios/plugins/check_arcconf.sh -w 50 -c 70
RAID WARNING, 0 numParityErrors, 0 hwErrors, 68 mediumErrors
As nagios user I am getting
[root@dbs01-ple03 ~]# su nagios -s /bin/bash -c "/usr/lib/nagios/plugins/check_arcconf.sh -w 50 -c 70"
(standard_in) 1: parse error
/usr/lib/nagios/plugins/check_arcconf.sh: line 56: [: : integer expression expected
/usr/lib/nagios/plugins/check_arcconf.sh: line 60: [: : integer expression expected
RAID OK, numParityErrors, hwErrors, mediumErrors
Can you please suggest a way out to deal with this problem?Thanks in advance,

[agriffin]

All you have to do is log in as root and run the plugin. I suspected you were already doing that to test it; if that wasn't correct please say otherwise.

[Shivaramakrishnan]

On the Nagios Server,I am running the command as root
ngo01.atl2:/etc/nagios3/conf.d# whoami
root
ngo01.atl2:/etc/nagios3/conf.d# /usr/lib/nagios/plugins/check_nrpe -H 10.12.10.146 -c check_arcconf
RAID OK, numParityErrors, hwErrors, mediumErrors

[agriffin]

Something in your script has insufficient file permissions. I can't get very detailed without seeing the source, but it looks like it's whatever is supposed to set the variables used on lines 56 and 60. You could either try to modify the script to work without root permissions, or you could use sudo to run it with root permissions.

Here is the script.Help me out.
