Polling Dell OpenManage via NC_Net

I’m trying to poll one of our clients Windows 2003 server which has OMSA installed. I’ve been looking around to see if it’s actually possible to do this via the check_nt plugin which has been recompiled with the additional functions of NC_Net.

Ideally I’d like to poll openmanage sensors such as temps and RAID health via a check_nt poll but i’m not keen on opening up port 161 on the router.

So far I’ve only come up with an active check that sends a query as:

check_nt!WMICHECK! -H -l “cimv2^select name,status from CIM_Fan”

but the result comes back as:
instance of Win32_Fan
{
Name = “Cooling Device”;
Status = “OK”;
};

instance of Win32_Fan
{
Name = “Cooling Device”;
Status = “OK”;
};

instance of Win32_Fan
{
Name = “Cooling Device”;
Status = “OK”;
};

to which Nagios has no idea what to do with the data.

The only other way I could see this working is to have a passive check that runs on the server, but i have no idea on where to start with that.

Apologies in advance if I should be posting this elsewhere

Thanks
