A nice feature of the AR Server is the Server Events table - but unfortunately it contains numeric codes and it´s really hard to read them. This small application "Server Events Decode" allows to look at the recorded server events and get the "official" explanation from BMC. The included data is based on the 9.x documentation (Thanks to Emre for updating it). It´s simple, it´s easy, but I did not find it anywhere else.
I´m not sure if all events are mapped, but you will recognize if the description is missing (outer join).
Do not forget to enable the server events in the BMC Remedy AR System Administration -> General -> Server Information, tab Server Events.
