Goal
Support for SNMP Informs in Trapd Collector Service
Note: A TRAP is a SNMP message sent from one application to another (which is typically on a remote host). They're purpose is merely to notify the other application that something has happened, has been noticed, etc. The big problem with TRAPs is that they're unacknowledged so you don't actually know if the remote application received your oh-so-important message to it. SNMPv2 PDUs fixed this by introducing the notion of an INFORM, which is nothing more than an acknowledged TRAP. IE, when the remote application receives the INFORM it sends back a "I got it" message. This is nice because then the person sending the traps can keep trying until the trap gets through. The net-snmp snmptrap program can send both TRAPs and INFORMs. Add -Ci to the command line of snmptrap if you want it to send an INFORM instead, or call the snmpinform command (which is functionally the same as snmptrap -Ci). Note that you must use snmpv2c or snmpv3 to send INFORMs. snmptrapd is able to receive and display both INFORMs and TRAPs.
