[AGENT++] Traps

[Fehde, Marcus]

Are you planning to implement a denial of service attack? What is you
definition of a "very high volume"?

You should use traps only for rising alarms and for getting the
attention of a management station (called trap directed polling).
Furthermore Inform-message are critical and can flood a network,
particularly because they have to be acknowledged by the server and
they're re-send if either the request or the response got lost. Even
though Inform-messages can be sent by agents they should be only sent
between management stations.

Regards,
Marcus

Have you tried using informs instead of notifies?  Informs require
acknowledgement.  If acknowledgement isn't received, the trap generator
is suppose to re-send the inform.

I have found that when sending a very high volume of traps, if the
processing of the trap is to high then traps are dropped (I assume on
the socket level). I have seen this on multiple trap applications
(code). The solution to this is to dequeue all traps to another thread
so that all processing does not occure on the thread of the socket. Is
there a way to solve this in snmp++ since the internal processing is to
high and even if I do nothing but count the traps, some get dropped?
