One method that hasn't been mentioned is to collect the alarm messages
directly. The program alm_line on www.thecassandraproject.org is a
program which registers as a pseudo-device which can have alarms sent
to it. This particular program sends those alarms to the message line
on the operator display, but you can do anything you want with the
alarms using a similar process.
The code on the Cassandra site works for older versions of I/A
(4.2/6.0 and before I believe). The alarm message format changed
slightly around 6.1 or 6.2, so the code needs to be slightly modified
for use with more modern systems. It's probably easier to just use
the alarm message header file (/usr/fox/include/alarmmsg.h) than to
define the alarm structure in the code.
My favorite application of this type so far is Sean Redmond's (Foxboro
New Zealand) talking alarm manager. As I recall, he sent the alarms
to a linux PC over 2nd ethernet (sockets) with a voice synthesizer
which would speak the alarm. I think priority 1 alarms also said
"Danger, Will Robinson!", and priority 2 alarms said "Warning,
Warning!".
