Issue with CPU monitoring using WMI

Any reason why you would use WMI over SNMP?  SNMP provides interface datga as well as topology data where WMI does not.  Also, you can use the SW free tool called SNMP Enabler to install the snmp service and configure it remotely.

I've setup SNMP monitoring on another server but I'm not seeing CPU/Memory usage dials and the network topology info is missing - so I don't see the benefit at the moment.

So when you added the device into Orion, you chose SNMP?  You added the string and hit test?  Once it tested green and you hit next, it should have polled the device.  It will then give you the ability to check the objects you want to monitor including CPU & Memory (up top for the gauges), Topology (Layer 2 and/or Layer 3), and then a section for volumes and another for Interfaces.

There are 2 spots for Memory.  The top check box is for the gauges and the one in the Volume section is for adding physical and virtual memory to the volumes list on the Node details.

I hope this helps.  It is definitely recommended to use SNMP over WMI since SNMP is much more standard, works on most all devices, and most of all, provides data you just cant poll using WMI.

It doesn't help unfortunately - I see no difference when monitoring windows servers using WMI or SNMP, the same information is visible using either method on the same box. I have moved the server onto SNMP and the CPU information is still not visible. On another server (being monitored with SNMP) the network topology info is missing but one one being monitored by WMI it's there?

This is quite odd and unexpected behavior.  What OS is running on that box?

Server 2008 R2 - seems to have caught up now, it took a few hours to show the CPU info for that server so I guess patience is a virtue!

Interesting.  It should not take that long though.  I would check to ensure you have provided enough resources for not only your DB server, but also your Orion server.  It sounds to be one or both may be experiencing a lack of resources.

SNMP like stated above will give you Interface statistics, but the biggest value in my opinion is that it's much lighter than WMI and not dependant on as many other Windows services to function properly, and you aren't having to pass credentials to login and poll WMI through RPC.
