Nagios Support Forum

I have Nagios 3.3.1 installed on CentOS 5.8. I'm trying to make a shell script to use the ipmimonitoring function of freeipmi to gather Temperatures from Sun ILOM.

My script is written as below:

[root@localhost libexec]# vi ipmimonitoring.sh
#!/bin/bash

TempFile=$(mktemp)

STATUS=$(/usr/local/sbin/ipmimonitoring -u test -p test -l user -h $1 -W endianseq | grep "mb.t_amb")
echo $STATUS > TempFile

Check=$(grep "OK" TempFile)

if [ "$Check" != "" ];
then
ECHOOK="Temperature OK, Result: $STATUS"
echo $ECHOOK
exit 0

else
echo "WARNING: Temperature NOT OK, Result: $STATUS"
exit 1
fi

rm -f $TempFile

When I execute it in the command line, it works fine:
[root@localhost libexec]# ./ipmimonitoring.sh 10.20.60.12
Temperature OK, Result: 4608 | mb.t_amb | Temperature | Nominal | 28.00 | C | 'OK'


But when I execute it in Nagios, it always goes to the else condition even if it is picking up the Temperature:

define command {
command_name ipmimonitoring
command_line $USER1$/ipmimonitoring.sh $HOSTADDRESS$ }


Nagios Webpage Output is:
Current Status: WARNING for 0d 0h 56m 23s)
Status Information: WARNING: Temperature NOT OK, Result: 4608
Performance Data: mb.t_amb | Temperature | Nominal | 28.00 | C | 'OK'
Current Attempt: 3/3 (HARD state)
Last Check Time: 05-19-2012 00:36:08
Check Type: ACTIVE

I have done pre-flight check and service nagios restart but the problem keeps recurring.

Please advise if I'm doing something wrong. Thanks in advance for any help.

I don't have ipmimonitoring to test against, but I cleaned up your script a bit and fixed some bugs you had with quoting and writing to a file literally named TempFile (rather than the variable $TempFile). Also, pipe characters in plugin output are treated special by Nagios, and should be avoided unless you are providing performance data for graphing. See if those changes help.
When you test your plugins, you should be running them as the Nagios user to make sure there are no permission issues. For example:

Thanks for your quick reply and for helping to fix my poor scripting.

The script works. Turns out that nagios as a user doesn't have permissions to access TempFile while root had it.

Thanks a lot again.

You're welcome!
