489 | This provides a kernel interface for creating and updating z/VM APPLDATA | |
490 | monitor records. The monitor records are updated at certain time | |
491 | intervals, once the timer is started. | |
492 | Writing 1 or 0 to /proc/appldata/timer starts(1) or stops(0) the timer, | |
493 | i.e. enables or disables monitoring on the Linux side. | |
494 | A custom interval value (in seconds) can be written to | |
495 | /proc/appldata/interval. | |
