Hello John,

I used 
http://www.whiskey-tango-foxtrott.de/wiki/doku.php?id=linux:debian:snmpd 
as one of the docu's.

Since I am not sure what you mean with the version, i am assuming you are 
talking about the debian machine. That is the last stable release of it. 
This goes for the snmptt and trapd aswell.

Since the last mail i did figure out some stuff. It seems i dont even need 
snmptt to get the traps to work. I started the trapdeamon with the 
following command: snmptrapd -Oa -C -c /etc/snmp/snmptrapd.conf -Lf 
/tmp/log.log

In the logs i noticed then that the traps where sending there own id 
(1001) along with the rest:

2012-07-17 08:20:44 192.168.103.5(via UDP: 
[192.168.0.5]:32768->[192.168.0.11]) TRAP, SNMP v1, community public
        SNMPv2-SMI::enterprises.3183.1.1 Enterprise Specific Trap (1001) 
Uptime: 434 days, 14:21:57.89
        SNMPv2-SMI::enterprises.3183.1.1.1 = STRING: 
"DELLK..T.S..O05J...ZH6.. !....................XEN01.."

So i opened the snmptrapd.conf and i added the following lines:

traphandle SNMPv2-SMI::enterprises.3183.1.1.0.1001 
/usr/lib/nagios/plugins/handle-dell-openmanage-trap 1001

The script itself just checks the id and then gives nagios the 
notification that in this case its a test trap. 

What still is bothering me though is that there is no way to monitor the 
raid controller or hard disks from the idrac itself. Does anyone perhaps 
have a solution for that without the use of dell openmanage or the 
openmanage essentials software?

Met vriendelijke groet / With kind regards,
