check_snmp_disk_monitor help

[nagiosgk]

I am trying to get the contrib file to work via Nagios. I have tried various iterations of command definition and service definition and cannot seem to make this work (I get an unknown status return and a timeout). Where I am at now is below.

It works fine via the command line:
./check_snmp_disk_monitor.pl -H sys1 -C sys1read -m / -w 75 -c 90

I copied the perl script to libexec, chowned it nagios:nagios, chmod'd 755

In the commands config:
define command{
command_name check_snmp_disk
command_line $USER1$/check_snmp_disk_monitor.pl -H $HOSTADDRESS$ $ARG1$
}

define service{
use lab-generic-service
host_name sys1
service_description Root Partition
check_command check_snmp_disk! -c sys1read -m / -w 75 -c 95
}

Also is there a log file or method that logs what gets passed to the program? It would make it easier to debug this and the event logs do not have enough information.

thanks

./check_snmp_disk_monitor.pl -H sys1 -C sys1read -m / -w 75 -c 90

check_command check_snmp_disk! -c sys1read -m / -w 75 -c 95

One of these C's is not like the other. I'll give you a hint, it follows the exclamation mark

Thanks for the reply. that wasn't the cause in my case (i just typoed the other C when i was making the post) but i figured it out. I would have posted sooner but I needed to wait on my post to be approved.

What I found out after looking at more snmp examples at the exchange is in order to make this work i needed to call it differently. The big break was learning to define the snmp community string as a USER variable, no more timeouts. Since then I also moved to using a different script but the correction to using a variable worked in my previous testing.

1. define a user in the resource.cfg file like this : $USER7$=-C snmpreadcomm
2. define the command
# 'check snmp_storage
define command{
command_name check_snmp_storage
command_line $USER1$/check_snmp_storage.pl -H $HOSTADDRESS$ $USER7$ -m $ARG1$ -w $ARG2$ -c $ARG3$ $ARG4$
}

3. define the service
define service{
use generic-service
host_name device1
service_description Root Partition
check_command check_snmp_storage!/!75!95!-r
notes /Root Disk Usage.
notes_url device1-troubleshooting.htm
}

Ah is point #3 a reference to the new script you are using? Thank you for letting the community know the solution to your issue.

Ah is point #3 the new script you are using? Thank you for letting the community know the solution to your issue.

glad to share. Point 3 references the command definition check_snmp_storage which calls check_snmp_storage.pl, which is the new script I am using now.

Prior to moving to this new script I was able to fix the issue I was having using check_snmp_disk_monitor.pl by creating the USER7 variable and updating the command definition to take that and the other varbinds correctly. More of a learning issue on my part on figuring out the "what and how" and not an issue with the old script.
