Dmonitor_sched.rst1 Scheduler monitors
5 - Type: container for multiple monitors
11 Monitors describing complex systems, such as the scheduler, can easily grow to
14 Often it is possible to break such descriptions into smaller monitors,
15 sharing some or all events. Enabling those smaller monitors concurrently is,
21 It includes several per-cpu and per-task monitors that work independently to verify
25 monitors, whereas sched itself is a *container*.
26 From the interface perspective, sched includes other monitors as sub-directories,
27 enabling/disabling or setting reactors to sched, propagates the change to all monitors,
28 however single monitors can be used independently as well.
