Unfortunately this is far more complex than it should be in my opinion.  The way it was explained to me is 'back in the day', SNMP was tied to things such as router restarts, etc..  Which, if SNMP was restarting, it was because the piece of equipment was being restarted.  Now a days, the use of SNMP is now used more  'perversely' because it is tied to things such as services, and they can restart and doesn't mean a system has gone down or been rebooted.
