Application Event Error Report Message Classes and Event Types

Hello,

Is there a resource or page in the help center that has a list of the different Application Event Error Report Message Classes, Event Types, and message descriptions that typically appear when the report is generated? I know about the Integration Messages page in the help center but need assistance figuring out what other items such as RepackagingTriggerEvent (PACKAGING_WARNING) and CalculateNewPackageEvent (SCRIPT_ERROR) may generally mean.

Thank you.
