The VAX/VMS Monitor Utility allows you to monitor classes of system-wide
 performance  data   at  a  specified  interval.  It produces three types
 of optional output:

    o  Recording file
    o  Statistical terminal display
    o  Statistical summary file

 You  can collect data from a running system or from a previously created
 recording file.

 The  MONITOR  Utility  is  described  in detail in the VAX/VMS Utilities
 Reference Manual.
