Shown Invalid Service Status Value in Nagios network application

Hi
Iam using nagios network application when i trying to found service status value.But finally it shown invalid status value in nagios application. I wrote a code as mentioned below



#!/bin/sh
host="$1"
service="$2"
/etc/init.d/$service status | while read t
echo $t
do
if [[ "$t" == *running* ]]
then
echo "Service is running "
else
echo "Service is stopped"

fi
done


But as mentioned above code running in command prompt on fedora linux,it shown a correct service status value.But when i trying from nagios.It shows a invalid status value.

If any plugins for checking a service status value or any modification. Please suggest to me on this issue.

Re: Shown Invalid Service Status Value in Nagios network application

The 'while read' part might be messing things up. Looks kinda strange to me.

This minor edit seems 'safer' to me already:

t=$(service $2 status)
if [[ "$t" == *running* ]]
then
echo "Service is running "
else
echo "Service is stopped"
fi

G'luck !

Re: Shown Invalid Service Status Value in Nagios network application

Sorry.. this complies more to your example (probably more clear):

#!/bin/bash
host="$1"
service="$2"

t=$(/etc/init.d/$service status)

if [[ "$t" == *running* ]]
then
echo "Service is running "
else
echo "Service is stopped"
fi

Still quick 'n dirty, though..

Can you run it ok when you're su'd to the nagios user account ?

Re: Shown Invalid Service Status Value in Nagios network application

Asking the above because I just saw this on my OEL (that's pretty much a RedHat):

[root@orabox ~]# /etc/init.d/xinetd status
xinetd (pid 2660) is running...
[root@orabox ~]# su - user1
[user1@orabox ~]$ /etc/init.d/xinetd status
[user1@orabox ~]$

--> No output when running from the user account

Re: Shown Invalid Service Status Value in Nagios network application

Personally I would have my script check for the actual processes in a ps command, but if you want to you could add an entry like this in your sudoers file:

nagios ALL=NOPASSWD:/etc/init.d/service1 status, /etc/init.d/service2 status

This way, nagios should be able to run the scripts as root, and only with the 'status' option.

Cheers,
Wout
