Login to the remote server, run the following and post the output.

Code: Select all

su - nagios
bash -x /usr/local/nagios/libexex/check_ifx.sh
/usr/informix/bin/onstat -

Please send the entire sanitize output of these commands:

Try it as the nagios user (run these exact commands, including the minus in su - nagios), if this doesn't work, it won't work through NRPE:

Code: Select all

su - nagios
/usr/informix/bin/onstat -
My question is do you need to su to your informix user in order to run the onstat - command? That is what we needed to do because all of the permissions/envars/etc were based around that when I was an informix server admin (this was 5 or 6 years ago so I am by no means an Informix expert, we also ran it on AIX so it's a bit different).

I am starting from scratch on the debugging so that we can get this resolved for you, I will test in my environment to make sure it works and then we can focus on yours (to debug the issue), first we need to validate that it actually works the way we are trying but because we do not have any informix systems here we need the output to test.

Thank you

you quesiton?
My question is do you need to su to your informix user in order to run the onstat - command?
It can run as informix or root.

Code: Select all

[root@huey libexec]# su informix
[informix@huey libexec]$ onstat -

IBM Informix Dynamic Server Version 12.10.FC8W2WE -- On-Line (Prim) -- Up 3 days 02:43:41 -- 1034088 Kbytes

[root@huey libexec]#
I usually run the onstat - command via root but both will work. Hope this helps.

As root, what is the output of this command:

Code: Select all

env
Then send the output of these commands and see if it works:

Code: Select all

su - nagios
sudo /usr/informix/bin/onstat -

We found that the Informix onstat command needs to have some environment set as the command uses them when it is executed.
The reason the root and the informix user works, the variables are set but the nagios user account does not.

So edit the check_ifx.sh script and change it to the following

Code: Select all

#!/bin/bash
#
# check_ifx - plugin to validate that informix is onlinea # # # parameters # 1) Informix directory # 2) Informix server
export INFORMIXDIR=/usr/informix
export INFORMIXSERVER=hueynet
export ONCONFIG=onconfig

result=`/usr/informix/bin/onstat -`

for cmd in $result
do
  if [ $cmd = On-Line ]
  then
	echo $result
	exit 0
  fi
done
echo "CRITICAL"
exit 2
Save it out and see if it works by running

Code: Select all

su - nagios
/usr/local/nagios/libexec/check_ifx.sh
If you use this script on another server, you would have to edit the following lines if needed.
The INFORMIXSERVER line for sure will have to be edited.

Code: Select all

export INFORMIXDIR=/usr/informix
export INFORMIXSERVER=hueynet
export ONCONFIG=onconfig
