There's an "snmptrap" command that you should look into. This is a
command-line utility for generating an SNMP trap message and sending
it somewhere; this should run from a custom alert script that you 
invoke from the hobbit-alerts.cfg file.

If your Hobbit server has the Net-SNMP package installed, there's some
documentation about how to generate traps in their FAQ. See
http://www.net-snmp.org/docs/FAQ.html#How_do_I_send_traps_and_notifications_

The biggest issue might be to find out what OID to use when sending the
trap. The OID (Object IDentifier) must be recognized by your HPOV 
installation - it must be described by a MIB file that is installed in
the HPOV management system - so it knows how to interpret this trap.
E.g. a trap stating that "Item 4 now has value 80" doesn't mean much 
unless you know that that "Item 4" is the temperature of your CPU and 
"80" is in degrees Celsius.

You can make up your own OID's, as long as you make sure they are
defined by a MIB. It's customary to use OID's within the "enterprises"
section of the OID tree. Big Brother uses an OID of 1.3.6.1.4.1.7058 
which is such an "enterprise" OID registered as the top-level OID for 
"BB4 technologies".
