When any agent sends a trap the origin is an IP address, and in the case of
netmon traps, it starts out as the address of your NetView box.  But to be
consistent with agent traps, trapd substitutes the hostname of the box the trap
is about, which he got from netmon, and that  is why for NetView traps,
$NVATTR_2 and $NVA should always be the same.  They will be hostnames unless
netmon and trapd were unable to resolve the IP address originally.

Yeah, you misinterpreted; I follow how it works ;).

The description of NVA states that is is the "agent address."  This
makes me think it's an IP address, which wouldn't be very informative
info to send in a mail...if it's actually the hostname (NVATTR_2), then
great, less typing!
