Well the way I see it is, if you're specifying the OID's you want to check,
from particular IP's you don't need additional filtering. You ignore
anything that doesn't conform to the properties of your checks. The alert
wouldn't be generated just because a trap was received but because the value
in the OID matches what you're checking for. This effectively filters all
traps received whether they've been generated for a specific reason or
because the device sends periodically for status (once every 2 mins). As far
as an alert status being found every two minutes, the alert settings (more
or less as they are) would be where you specify how often to perform the
actions.

Lots of people specified an interest in this when it was previously
discussed. C'mon, let your voice be heard or forever hold your peace!

Well the points that you're talking about are those that were already clear
for me :-)
The fuzzy part is how exactly people want to filter.
If you look at how a trap works you would see that within a trap you can
have different objects.  So the big question is do they want to filter on
one object per trap or a combination of multiple object per trap, also what
about devices that send out traps every 2 minutes just to give an
update...should that generate an "alert" each time or should there be some
kind of rule for it too.  And what if you create a "generic filter" were
that trap (of the device that sends every 2 minutes) fits will the generec
trap be flagged as already send and don't resend, that could block alerts
for other traps that also fit that "generic filter"....
Well looking at the huge responses (one until now :-() maybe it's not such
an important feature...


Dirk.

Hi Dirk,

Please bear in mind I'm still a bit fuzzy on exactly how traps work. That
said...

I think it would be great if SA could gen an alert based on traps received.
I suppose, in the setup you should be able to specify MIB's which you want
to use (in addition to standard ones), such as APC. You'd also need to
specify IP's to accept/reject. Then (somewhere) you'd be able to specify
that you want an alert generated on a given OID meeting specified criteria
(much the same way as the existing SNMP check). I'm not sure how best to
integrate these checks into the monitor window, as they don't run on cycles.
I guess that'll have a lot to do with difficulty of implementation.
Possibly, you could have an option under the View menu to show/not show
monitored traps. When you are showing them you could split the main window
(horizontally), with the top (majority) part showing the normal view and
have the bottom (scrollable panel) part showing which traps are being
monitored?

Some people seem to be wanting alert on the received traps.
I would like to get some more insight on what exactly you want to do.
Aspecialy how you want to "filter" what received traps should generate an
alert and what (of those traps) should be within those alerts.


Dirk.
