Setting up the z/VM guest virtual machine

You must enable your z/VM guest virtual machine to write monitor records and configure the z/VM system to collect these records.

Procedure

Perform these steps:

  1. Set this option in the z/VM user directory entry of the virtual machine in which the application that uses this device driver is to run:
    • OPTION APPLMON
  2. Issue the following CP commands to have CP collect the respective types of monitor data:
    • MONITOR SAMPLE ENABLE APPLDATA ALL
    • MONITOR EVENT ENABLE APPLDATA ALL

    You can log in to the z/VM console to issue the CP commands. These commands must be preceded with #CP. Alternatively, you can use the vmcp command for issuing CP commands from your Linux instance.

    See z/VM: CP Commands and Utilities Reference, SC24-6268 for information about the CP MONITOR command.
