I am setting up some monitoring on some Windows infrastructure and am having problem locating the ODI's that I am after. Effectively what I need are the ODI's for the following
1) % of CPU utilisation (either used or free).
2) Disk Free
3) % of Free Memory (or bytes)
I am doing my testing on XP but will be deploying to 2003/2008.
I suspect your SNMP agent will implement the host MIB, and that contains the relevant disk/cpu information. The data is structured in quite a complex fashion, and often the easiest way to find what you want is simply to browse through with a MIB browser.
