System Resource Monitor/Graph

I'm looking for an app that does about the same thing at the Performance tab on Task Manager, but on a per-process basis and with more plotted values. At a minimum, I would like to be able to plot CPU and memory usage but it would be nice if it could plot:

Network usage
File system IO (per drive/share sub headings would be nice)
Open file stream count
LSOF like stuff
All the other stats that the Process tab can give you
... anything else ...

Solution

Windows comes with perfmon which is pretty much exactly what you want. It has infinity different counters with different categories - also individual apps can register their own counters.
