As I am looking for more to happen than offline the page via soft or hard offline when the threshold is exceeded, and it would be beneficial to have a custom script trigger.

Triggering with thresholds makes sense. Yet, as the event trigger starts 
an script, it would be possible to use it to check for thresholds inside
the script itself. Not sure what would be the benefit to embed the event
threshold calculus inside rasdaemon. Granted, it can query the database to
better detect thresholds.

On that sense, one thing that I'm considering is to extend the DB interface
for it to work with other databases (MariaDB/MySQL, Postgres,...) and have 
a better data model to help taking such policy decisions. Patches to
take such approach are welcomed.

Yet, if you have something already coded, please send a PR to github.
I'll review there. You may also open an issue for us to discuss it there
and keep track of its progress.

It very much depends on how much time I have to take a look on userspace
code. I'm intending to review a bunch of pending stuff maybe next week
or at the week after that.
