I'll explain and clairify what I know..
First, netmon polls every interface that it is managing, which may or may
not be what's listed in the seedfile. Seedfiles can be complicated and
powerful, so be sure to read the section in the Installation Guide (Chapter
8, I believe).
Netmon polling generates the "standard" Netview traps, such as
Node/Interface Down/Up, based on its polling, and update the map status and
colors accordingly. Agents running on your network devices can also send
traps to Netview. These unsolicited traps are defined and managed by the
vendor and agent; when and how they occur can vary with each implementation.
Specifically, I've only used the SIA to poll for MIB values, so I do not
know what threshhold you may be able to set within it.
As for trapd.log, all events will go to trapd.log, unless the particular
trap has been modified to not be logged.

Subject: Question about traps and netmon..
Hello All.
This is a general I have in the process of trying to understand Netview
better...
I understand that Netview uses the netmon daemon to 'poll' the devices
in the seedfile.
But, can/do devices generate traps on their own within polling periods
if a MIB value changes. Where/when exactly do the traps occur or does
netmon do everything associated with trap generation.
Also, can subagents like SIA generate a trap and send it to Netview
without netmon do a poll, i.e. in between polls.
Finally, do all the traps sent to Netview go to the trapd.log file or
just the ones that are sent to the Events Display?
Any info appreciated.
Gord.
