ALTERNATIVES TO (?): RE: How do I get the DISMAN-TRACEROUTE-MIB "into" my SNMP Agent?

Wes,

Thank you for your reply.  Perhaps you saw my earlier, much larger post,
in which I explained that I can produce a "tables" of values for hosts
that I traceroute to using arbitrary agent extensions and scripts.  

I can produce the following:
- A list of hosts to which the server is performing traceroutes
- An enumeration of the list of hosts I am tracing to (e.g., 1, 2, 3, N)
- A count of the number of hosts I am tracing to (e.g. 9)
- A list of all of the hops along the traceroute for a particular host
(generally a list of the consecutive IP addresses the traceroute "hops"
through to the remote host)
- An enumeration of all of the hops to a particular host (e.g., 1, 2, 3,
4, 5, N)
- A count of the hops to a particular host (e.g., 6)
- The hop interval in milliseconds for each hop

What I was asking, and no one has answered, is this: Is there a way to
structure the entries in the snmpd.conf file so that the overall
function behaves something like the IF-MIB?  By that I mean, if you walk
the IF-MIB on a various hosts, it automatically knows how many
interfaces there are, what they are called, and various pieces of
information about each (speed, errors, etc.).

At present, I have to create a distinct entry and OID for every hop of
every host I traceroute to.  I would rather be able to walk the
arbitrary extension OID "tree", if I can create such a thing.  

I simply do not have the necessary experience to make this work.  I have
built some OID structures, attempting to mimic the structure of the
IF-MIB (e.g., providing an ifIndex, etc.), but the results are no good.

I don't know whether it matters or not, but I am using Cacti to poll and
manage this data.  The server running Cacti is a Centos 5 box.  It is
polling, primarily Solaris 10 servers, which have the 5.0.9 agent that
ships by default with Solaris (and does not support the extend
directive).  The entries in the snmpd.conf file are on each server
performing traceroutes.  If having access to the extend directive would
solve my problem, I could see about upgrading, but these servers run
hyper-critical functions, so that may not be possible.

If you, or someone, could even tell me that what I am trying to do isn't
possible, I'll just slog along with individual entries.  This method,
however, offers no flexibility to me if a route changes, even though the
scripts collecting the traceroute data will shift and produce new route
lists if the route changes.  In that case, I would not know that I was
missing those hops until I checked.  Then, I would have to build
additional OID's for them.

I have attached the e-mail with previous details.

Thanks in advance for whatever advice you can offer.

It's not compiled in by default and you'd need to use
--with-mib-modules="disman/traceroute-mib" in order to get it compiled
in.

That being said, the code is incomplete and I don't think even compiles
correctly at this time.
