I would like to add my emphatic agreement to Dexter's post. I have a nearly-all Procurve shop, with close to 100 switches, and it would be really useful to be able to monitor CPU and memory utilization.
According to HP's site, two key memory OID's are:
Memory used: 126.96.36.199.188.8.131.52.184.108.40.206.220.127.116.11.1.7.1
Memory free: 18.104.22.168.22.214.171.124.126.96.36.199.188.8.131.52.1.6.1
The problem is that there is no "resource" within the HP switch called "CPU and Memory Utilization" to select for monitoring like there is for Cisco. Can we please see this feature added?
