Dell OpenManage Support

For Dell OpenManage support, install Dell OpenManage 5.1 or later on the device to monitor. Make sure that net-snmp uses srvadmin. The configuration looks like this:

master agentx
view all included .1
access notConfigGroup "" any noauth exact all none none
smuxpeer .1.3.6.1.4.1.674.10892.1

Restart net-snmp:

service snmpd restart

Make sure that srvadmin runs. This command usually starts it:

/opt/dell/srvadmin/sbin/srvadmin-services.sh start

Then add the device to LibreNMS in the normal way. LibreNMS then collects the temperature data and the fan speed data.

Windows

Download OpenManage from Dell's support page Link and install OpenManage on your Windows server. Also install and start SNMP on your Windows server.
