Writing z/VM monitor records

Red Hat Enterprise Linux 9.2 z/VM guest

Applications can use the monitor stream application device driver to write z/VM monitor APPLDATA records to the z/VM *MONITOR stream.

For an overview of performance monitoring support, see Performance monitoring for z/VM guest virtual machines.

The monitor stream application device driver interacts with the z/VM monitor APPLDATA facilities for performance monitoring. A better understanding of these z/VM facilities might help when you are using this device driver. See z/VM: Performance, SC24-6301 for information about monitor APPLDATA.

The monitor stream application device driver provides the following functions:

  • An interface to the z/VM monitor stream.
  • A means of writing z/VM monitor APPLDATA records.
