Software for measuring resource usage?

[rjbull]

Lots of threads have remarks about the resource usage of various programs, so much CPU etc.  What's the best program for tracking resource usage?  Looks like you'd ideally need something like a chart with resource usage plotted against time.

TIA...

For CPU, memory, file access, paging etc Process Explorer from Sysinternals plots extensive values and some indivdual graphs per application and for the system overall:

If you want to monitor file / registry access in detail the Process monitor from the same:

The analysis functions in Process Monitor are great, grouping file access per file for read/write etc.
