It appears our NPM (version 9.2) is no longer able to poll CPU stats from Cisco 3550 switches. It seems to work on others, and has in the past (version 8.x) but once I upgraded, the stats no longer appear and are not being collected.
Anyone else have this issue with other gear?
Looking at the raw data, it suddenly drops to zero after the upgrade, and once in a while you will get a "1", but everything before that was in the teens.
