Re: My process is blocked while sendin a trap

When I read this, it seems to say that there is no current way to use
more than one AgentX daemon for a particular MIB subtree...

Given an enterprise MIB (fictitious enterprise OID 30303 for NEWENT,
with NEWDEV being the new device)

I have an example portion of the MIB below.

I was planning on doing what I believe you describe in your post.

What I would like to do is have one Agent handle traps, another handle
GET/SET, or further partition the Agents for functionality and
performance. The Agents would be querying a device not on the server
where the Agent is running.

I have the Agent running on Linux (CentOS and RH Enterprise) and it is
sending traps generated from conditions on the remote device.

I have not gotten to the SET/GET portion yet....

So if I have 2 Agents, each handling separate sections of the private
enterprise MIB NEWENT, will this work?

Or will they try to "register" on top of each other?

Did I miss something in the documentation? ( I hate that as much as
others... :-)

In fact, I'm using trap mechanism to dispatch all errors arising in our

Chances that error messages will be sent massively are statically low...

Good.

But this scenario can occur, and this blocks my server... I just to try to
figure out if I can imagine a work around.

The plan I have in mind is to separate out the processing of incoming requests,
and generating notifications - use two separate AgentX sessions for
these two purposes.

That should help avoid the sort of collision that you're seeing.
But nothing will happen until after 5.4 is out.

The problem is that we have multiple servers that can potentially send traps.

That's OK. The problem is with having a single subagent that is both
sending traps and receiving requests at the same time. Having
several servers running in parallel doesn't raise the same issues -
they'll be using different sessions already. It's a problem that's
focussed on each master-subagent link individually.
