└─>Linux - VM Monitor Stream, base infrastructure
In linux kernel since version 2.6.12  
This provides a kernel interface for creating and updating z/VM APPLDATA
monitor records. The monitor records are updated at certain time
intervals, once the timer is started.
Writing 1 or 0 to /proc/appldata/timer starts(1) or stops(0) the timer,
i.e. enables or disables monitoring on the Linux side.
A custom interval value (in seconds) can be written to

Defaults are 60 seconds interval and timer off.
The /proc entries can also be read from, showing the current settings.
