What is the output of:

Code: Select all

/usr/local/nagios/libexec/check_hpjd -H 192.168.x.x -C public

And then after the command completes what is the output of:

Code: Select all

echo $?

[Adam]

Code: Select all

[root@localhost adam]# /usr/local/nagios/libexec/check_hpjd -H 192.168.2.160 -C public
No log handling enabled - turning on stderr logging ("Standby mode is on.")

Code: Select all

[root@localhost adam]# echo $?
1

After doing some digging online I am beginning to think this is a bug in CentOS 6 and/or SNMP.

[Adam]

This is what I get when I try snmpwalk

[rkennedy]

I don't see the proper SNMP return in your walk for a 'Ready' status. Here are a couple alternatives that may work, if it is indeed a cent6 bug.
- Try this plugin https://exchange.nagios.org/directory/P ... ck/details and see if it returns the correct result
- Modify this bash script to work for your needs, it will change the statuses that a script is outputting. It currently switches ok -> crit, and crit -> ok, with warning remaining the same. You will need to adjust the 'enter_the_script_here' with the command you're running over the CLI to check_hpjd.

Code: Select all

#!/bin/bash

# define vars
script=$(enter_the_script_here)

# switch OK to CRITICAL
if [[ $script == *"OK"* ]]
then
echo "CRITICAL"
exit 2

# switch CRITICAL to OK
elif [[ $script == *"CRITICAL"* ]]
then
echo "OK"
exit 0

# WARNING stays the same
elif [[ $script == *"WARNING"* ]]
then
echo "WARNING"
exit 1

# catchall UNKNOWN
else
echo "UNKNOWN"
exit 3
fi

After doing some digging online I am beginning to think this is a bug in CentOS 6 and/or SNMP.

So it's clear the plugin is not working correctly at this point, hence why you get a warning.

I suspect this is a permissions issue on your SNMP MIB files, what is the output of:

Code: Select all

ls -la /usr/share/snmp/mibs

Make sure this points to the location of your mibs directory.

I suspect these need to be set to root:nagios as that is what I'm seeing on my system.

Code: Select all

chown -R root:nagios /usr/share/snmp/*

Did this have any affect?

[Adam]

rkennedy do you have a default copy of snmp.conf? I suspect I have it set up wrong.
