If you use xnmtrap and examine NetView's 58720263 Threshold exceeded trap
you'll see what variables are included.  $3 is the threshold exceeded
message itself, $4 is the name of the MIB variable queried, and together
those make up what you see in trapd.log or the event window for this trap.
 There is no way to tell snmpCollect to add additional variables or perform
additional queries for you.   So if you want more information then you will
have to build a mechanism, probably a script of your own, to be launched
when that trap comes in, which would do the same MIB query you just did to
find the path, and record the results.  You could log it somewhere or you
could use snmptrap to issue another trap of your own design which included
the additional information.  Alternatively, you could do the same thing
with a ruleset  running in the background.  But either way, you are going
to have build the mechanism which retrieves the path and does something
with that information.
