That's up to the application generating the trap.
It will decide when a "significant event" has occurred,
and hence when it should send a trap.

Depends on the application generating the trap.

You can use the command-line tool "snmptrap"  to explicitly
send a trap request. See the man page for details.


> How to know if the NMS ... is receiving the traps?

Depends on the NMS system being used.
It may log incoming traps somewhere, or display a list
of them.  Or it may update the display status based on
that notification.
  See the documentation for your NMS system for details.

Anything you want it to.
It's typically a script (or sometimes a binary).
You can code this to perform whatever actions you wish.

Yes.   See 'local/traptoemail'  for a suitable script.
