What kinds of information does PCP collect?

[Mark Nelson <mark@xxxxxxxxxxx>]

Hi,

We are currently running collectl on our nodes here and collect data 
from the moab/torque logs to gather statistics about what is happening 
on our clusters.  I currently generate heatmaps and various other charts 
using some tools I've written (they are open source so let me know if 
you are interested).  I was wondering if PCP might provide us with any 
additional statistics beyond what we are getting via collectl and moab. 
 I've included some samples below of the kind of information that I'm 
gathering and plotting now:
