System alarm
We need an alarm alert for the user when a threshold is exceeded.
To do that, we need an event_manager
that will register to an event group. Kernel
will poll and check some thresholds. Whenever a threshold is exceeded, kernel
will send a message about that threshold to event_manager
. And then web_handler
will get alarms in event_manager and show it to the user.
I'd do it with CPU temperature threshold first.
