Not to worry, I've given up on this and resigned myself to the fact that I'll have to just rediscover every single device.   Now all of my services are showing up as yellow, despite discovery working great and the idrac view being very much full of details, the nagios checks are not working. This is via snmp to a C6420.
I have an existing Nagios Core 3.5.1 installation, and an OpenManage Enterprise server. They each monitor the same 500 servers, but on different levels (Nagios checking services, uptime, OME checking hardware health). I'd like OME to send its alerts to Nagios so I can see all alerts in the same place, rather than having to check both of them. This should also support tracking of downtime, etc, right? How do I do this?   It seems like the device discovery script included with the OpenManage plugin for Nagios is for individual servers I want to monitor, but I already have the servers inventoried in OME. How do I point Nagios to OME?
