Callisto Upgrade – Oct. 2012 (Automatic event linking)

The October update included adjustments to how and when related events detected by Callisto get linked together.  On occasion, e-resource providers exhibit oscillations between working normally and failing.  This Callisto update allows the system to link such outages together into a sort of “master event list”, so that Callisto won’t report all those oscillations via alert emails, and won’t show it as fixed by the provider until they return to normal for a longer period of time.
We also made improvements to the variety of subscription identifiers we can track.
