Totally. I used to write event handling rules for the Tivoli Enterprise Console, which used a Prolog dialect and a godawful DSL based on prolog. I had a ton of fun doing it... basically you had to write rules to normalize SMTP traps from various vendors, and take action based on them. Network vendors did all sorts of bizarre things -- one ATM would periodically send a "Interface Down" event, with an attribute set that meant that the "Down" event actually meant up! The hard part was actually doing anything with the events. The regime in charge of my division had a deep seated fear of automatic actions, even actions as simple as opening a trouble ticket.
