I just upgraded to SAM 6.2 and among other things, deployed the agent to a few servers for some testing. When I changed the servers polling mode from WMI to Agent, I got a warning that all historical data not supported by the new mode would be deleted, along with a link to 'polling mode comparisons'. The problem is the link really didn't say much with regards to what is supported by each mode. One would think that the agent would likely be able to do pretty much everything the other modes could do.
One thing I noticed in my 'Manage Nodes' page is that the servers that I deployed the agent to no longer can be expanded to show the NIC, Physical Memory, Virtual Memory or volumes. Is it not able to monitor these? Can the agent monitor everything, or are there things it can't monitor that WMI can?
