SNMP traps - sending interval

[ltrilety]

All alerts should generate an SNMP trap regularly e.g. every check interval.

Usual SNMP management counts with such behavior and moreover expects that. The main reason is that for SNMP traps a UDP is used, where the reasons for UDP usage are: because it's very quick and cost almost nothing. We could use SNMP informs instead of traps, but using them we lost those advantages. SNMP inform delivery is acknowledged by recipient, it's part of SNMPv2c.
We could use inform for sending clear alerts though as those will not be repeated and the speed and cost (there shouldn't be much of them) of delivery is not so important.

There's already a BZ for this:
