Create a saved segment for CP to store the monitor data

All Segment and Monitor commands must be entered from a userid with class E priviledge.

You can issue Q NSS MAP ALL to check for segment overlap and adjust the following command accordingly.

  • CP DEFSEG MONDCSS 1900-20FF SC RSTD
    • "Saved Segment MONDCSS ... " is a valid response
    • "Unknown CP command" either you mistyped the command or you do not have class E priviledge.
  • CP SAVESEG MONDCSS

Running CP Monitor

Setup the MONWRITE virtual machine

From the MONWRITE userid enter the following.
