Patent ID: 7681068

Claim:
A method of managing an event toggling between first and second event states in a network management system, said method comprising: listing said event and a last state change time of said event in a hysteresis table, if said event is not already listed in said hysteresis table; determining, by a processor, if said event maintains one of said first and second states for a predetermined amount of time, wherein: if said last state change time of said event plus said predetermined amount of time is not less than current time, then said event is deemed unstable and remains listed in said hysteresis table; and if said last state change time plus said predetermined amount of time is less than the current time, then said event is deemed stable and is removed from said hysteresis table; and reporting said event as having one of said first and second states only after said one of said first and second states is maintained for said predetermined amount of time, wherein said reporting said event as having said one of said first and second states comprises reporting said event as achieving said one of said first and second states at said last state change time of said event.
