In an Event Management System (EMS) (11), a method, system and agent (19) for processing an alarm update, wherein an agent receives from an alarmed network resource (14i) a first update alarm notification (50) with an alarm attribute, such as a severity attribute, set to CLEARED, followed by a second alarm update notification (60) comprising a new value of the attribute. Upon receipt of the first update (50), the agent (19) starts a timer for monitoring if the second update is received within a pre-determined period of time. If so, the agent discards the first update notification (50), and updates its active alarm list with the new alarm attribute, and further informs a manager (32') of the alarm change. If not, i.e. the pre-determined period of time expires and no second update is received at the agent (19), the agent (19) updates its original alarm (16) in its active alarm list with the attribute set to the CLEARED, and further informs the manager (32') of the attribute updated with the CLEARED state. |
