Overview
--------

	The ISD VMS Performance Monitoring System (PMS) gives
system management information on: service level (response time),
idle CPU time, average users, disk I/O, free memory, pagefaulting
and disk capacity. 

	There are seven command procedures which run in batch queues
and daily deposit data in files which are plotted as needed with
datatrieve procedures.   The cluster version requires that a separate
directory be created for performance data for each node.  A logical
must be created to point to the directory, for example, PERFORM5
points to the directory for one node; PERFORM6 to another, etc.
The command procedures must be modified so that the correct directories
are pointed to.
