[AGENT++] Trap implemantation puzzles

[Dario maljur]

Hi.

I have successfully managed to get over GET/SET/GET_NEXT  type of changing
and setting objects.

And now I'm doing traps but have some doubts on implementation of same.

Please correct me if I'm wrong, but this is what I figured out for now on
traps.

 

Initiation of trap mechanism is done on done on manager and it is done
pretty much like this in pseudo code:

InitTraps()

{

 set traps targets // withch are target agents (on different computers) to
listen to for traps and infos

 then set oids  // witch are object identifiers of mib-objects we want to
listen to

 then register callback function that will be triggered when trap that has
been registered fires from agent.

}

 

Int reason, Snmp *session, Pdu &pdu , TimeTicks &timestamp, CTarget &target,
void *cbd

Callback (Int reason, Snmp *session, Pdu &pdu , TimeTicks &timestamp,
CTarget &target, void *cbd)

This is callback function I'm using and if I understood correctly this is
where trap finishes it's journey from agent.

And I belive that trap id and value is in the Pdu.

 

And what about notify mechanism on agent, Do I implement notify in the from
object derived from MibLeaf or this is done somewhere else?

Say I got my RoomTemperature : MibLeaf object with some value of temperature
that is subdue to changes.

And now I want to set a trap on value of temperature to fire a notification
whenever value changes. Or to set trap when

Value exceeds 30 degrees or when is less then 0. Where do I Implement that.

Tnanks.
