Nagios returns service did not exit properly

VisRyanWilliams · Post by **VisRyanWilliams** » Mon Apr 14, 2014 9:15 am

I have a Nagios install which is working perfectly. Now I am a bit of a Nagios noob and not very good with my Linux commands but I have attempted to add a plugin to check disk space via snmp. The script I am using is called "win_check_snmp_disk.pl" which I obtained from Nagios Exchange. I have added this script in and created the command definition and service definition but the script returns a Nagios value of "Service check did not exit properly" and I am banning my head against a wall on how to solve so any help would be appreciated

What output do you get from the following commands?

Code: Select all

/usr/lib/nagios/plugins/added/win_check_snmp_disk.pl $HOSTADDRESS$ public 90 95
echo $?

From a quick peek, it looks like your code is fine, but it's hard to say.

Hi so I browsed to the location and then run the command and below is the following results

VSHMON41:/usr/lib/nagios/plugins/added# ls
win_check_snmp_disk.pl
VSHMON41:/usr/lib/nagios/plugins/added# /usr/lib/nagios/plugins/added/win_check_snmp_disk.pl $HOSTADDRESS$ public 90 95
ERROR: address argument not in correct format

I believe you have your plugin's name wrong. You should be running "check_win_snmp_disk.pl", not "win_check_snmp_disk.pl". What is the output, when you run the following command from the plugins directory?

Code: Select all

./check_win_snmp_disk.pl -h

You need to be running something like the following:

Code: Select all

./check_win_snmp_disk.pl x.x.x.x community 1 80 90
OK : Percent Used : 74.1%, Total : 452.9 GiB, Used : 335.8 GiB,  Free : 117 GiB

Hope this helps.

Hi

I have at this point started from scratch and replaced the plugin, done a new command and definition in case I made any mistake.

Code: Select all

define command{

        command_line    /usr/lib/nagios/plugins/check_win_snmp_disk.pl $HOSTADDRESS$ $ARG1$ $ARG2$ $ARG3$
        }

Service Definition

Code: Select all

#check disk space
define service {
        hostgroup_name                  netbios-ssn
        service_description             Windows-Check-Disk
        check_command                   check_win_snmp_disk!public!90!95
        use                             generic-service
        notification_interval           0 ; set > 0 if you want to be renotified
}

I then run the following

Code: Select all

VSHMON41:/usr/lib/nagios/plugins# ./check_win_snmp_disk.pl -h
Enhanced check_win_snmp_disk.pl by Dan Capper based on original script by jakubowski Benjamin
Reports disk usage of Windows systems via snmp to nagios

usage:
check_win_snmp_disk.pl [address] [community-name] [logical disk] [warn-level] [critical-level]
Where:
[address]       = ip address or name of server to check
[community-name] = SNMP community name with at least READ ONLY rights to server
[logical disk]  = Logical disk number of disk to check - on windows systems, 0 = A:, 1 = C:, 2 = D:, etc
[warn-level]    = Percentage full before return warning level to nagios
[critical-level] = Percentage full before return critical level to nagios
For example the command:
./check_win_snmp_disk.pl 10.0.0.10 public 2 80 90
Will check disk 'C:' on the server at '10.0.0.10' using snmp community name 'public'. Warn at 80% full, Critical at 90% full

Which returned the result

Code: Select all

VSHMON41:/usr/lib/nagios/plugins# ./check_win_snmp_disk.pl 172.16.233.109 public 1 80 90
.iso.org.dod.internet.mgmt.mib-2.host.hrStorage.hrStorageTable.hrStorageEntry.hrStorageUsed.1: Unknown Object Identifier (org.dod.internet.mgmt.mib-2.host.hrStorage.hrStorageTable.hrStorageEntry.hrStorageUsed.1)
ERROR : Unexpected result from snmpget

I'm seriously stumped

Can you run snmpwalk against this host?

Code: Select all

snmpwalk -v 1 172.16.233.109 -c public

Yes I can

It runs through printing a bunch of things out to the screen.

Post by **lmiltchev** » Wed Apr 16, 2014 4:56 pm

OK, run the following command:

Code: Select all

snmpwalk -v 1 172.16.233.109 -c public mib-2.host > /tmp/debug.txt

and post the debug.txt that was generated by running the above command.

Sorry for late reply

I have uploaded the debug.txt

The plugin is using a bunch of shortnames instead of numeric oids. Unfortunately your system does not seem to contain mibs to translate them to oids for sending to the remote system. You could certainly look at oidview or something similar for the mibs that will provide them, otherwise a different plugin would probably be easiest, and actually check_snmp_storage will likely do what you want out of the box.
