If you would like to use SNMP to monitor your dell server with OMSA (server administrator) installed, you have to configure your local SNMPd.

First you have to enable SNMP on OMSA:

/etc/init.d/dataeng enablesnmp

Than restart your Data Engine System from OMSA:

/etc/init.d/dataeng restart

You can now install the snmp daemon from debian:

apt-get install snmpd

SNMPd should listen to all interfaces. You can configure this at /etc/default/snmpd

Please note, that you have to remove the entry -I -smux, because OMSA uses snmp smux for communicating with the SNMP daemon.

The following snmpd.conf is tested to work with OMSA:

com2sec local localhost public
com2sec watchdog 192.168.168.0/24 public
smuxsocket 127.0.0.1
smuxpeer .1.3.6.1.4.1.674.10892.1
group MyRoGroup v2c local
group MyRoGroup v2c watchdog
view all included .1
access MyRoGroup "" any noauth exact all none none

Now restart the snmpd and install also the dell mibs. You can find the mibs in /opt/dell/.

After the restart you can walk throw your SNMP tables:

snmpwalk -v2c -c public localhost 1.3.6.1.4.1.674.10893

If you want to monitor the health of your server I can suggest you the following nagios plugin:

check_omsa_snmp.pl - this plugin checks temperature,voltage, Power Supply and Cooling Devices
