It sounds like the SNMP agent is not configured properly on some of those Dell servers. What agent are you using?
You could also Wireshark to see if the request/response is working and just not being processed?
Thanks for the reply but now I am even more confused. You said that maybe the SNMP was misconfigured on the servers yet I can do a WMI query from the command line of the Orion server to retrieve information yet I can't do so in APM.
I do not know the magic behind APM so I do not know what is being called when but it seems that if I can retrieve the data from command line WMI then so could APM.
BTW - I did load Wireshark and attempt a packet capture between the Orion server and the remote server and I can see DCERPC traffic when I do the WMI cal from the command line but nothing when I trip it from APM. Doesn't look like it is kicking off.
BTW - I also have a ticket open on this 121226
Paul O'Rourke in support had me try the action below which fixed the problem.
To register the WMI Scripting Type library:
swregtlib.zipand extract the
swregtlib.exeprogram to your Orion APM server.
- Click Start > Run on your Orion APM server, type
cmdin the Open field, and then click OK.
- Run the following commands in the command window:
