Adding CPU/Memory Resource

Question

Hello,

I have two identical Riverbed Steelheads added to NPM. When they were initially added, I specified CPU & Memory (along with a few interfaces) as monitored elements to one but not the other. I would now like to add CPU & Memory for monitoring to the first, but the option does not show up in the resource list.

I have been collecting NTA data from both for quite some time and prefer not to delete and re-add the device to get this information - I'm guessing I would lose the history if I delete the device.

Is there another method to re-add CPU and Memory to the list of available resources?

Thanks

I am not at all sure what happened here.

I had tried rediscovering the device in the past and it didn't change anything. When I rediscovered again today, the device showed as "Up" but with a red indicator. Hovering over the device had no indication of what the problem was. I could not find any alerts/events/messages associated with this device. When I hovered over the device in NTA, it said "one or more interfaces are down". I checked the status of all the interfaces and none that were being monitored showed being down.

I logged into the Steelhead to take a look around. Everything looked proper for the interfaces but I when I looked at the SNMP settings, I noticed the read community string was blank. I put the community string back in and saved the configuration than ran another rediscover from Orion. The "red" condition was gone and when I listed the resources the CPU/Memory box was displayed.

Since it appeared to be community string problem, I looked back at interface statistics expecting to see collection gaps - none exist.

I am now collecting CPU and Memory utilization.
