Running SAM 6.1.1
I am having the same problem with 2 VMware ESXi (5.5) Hosts
I know its not a router, but the behavior is identical.
and we have many ESXi's monitored successfully, including CPU and Memory.
No CPU or Memory monitored.
List resources and CPU /Memory box is unchecked.
Check the box and submit.
Still no CPU or Memory resources listed.
List resources and checbox is unchecked.again.
Support had me run the following query with no results found - so it's not seeing them as unchecked in the DB
(note: I did have a couple of nodes show up initially, but I was able to check the box and it stayed for the other nodes so currently no results from query)
SELECT * FROM [dbo].[Pollers]
left JOIN [dbo].[Nodes] ON [dbo].[Pollers].NetObjectID = NodeID
WHERE (PollerType LIKE '%Cpu%' Or PollerType LIKE '%Memory%') AND Enabled = 0
You could try to use OrionPollerCheckertool, to scan and select apropiate pollers for those devices, i had this problem and was that the poller checker tool didnt have a proper poller associated.
