Alarm reporting method

The method sets up relations of matching alarms. When receiving a new alarming, BAM establishes matching relations between the new alarm and active alarms. Then the new alarm is reported if the current condition for reporting alarm is satisfied. Relations of matching alarms are divided into two kinds: one is relation between the alarm and all other alarms of masking the alarm; looking up match relation for masking the alarm is realized through object fields of alarm are added for the reported new alarm; the other is coincidence relation between prearranged alarm group and all alarms in an alarm group. Through alarm matching, the method reduces amount of report inside module and between modules. Report in form of group instead of an alarm meets requirements of users. Though delaying moment of reporting alarm, the method reduces amount of report inside module and between modules. Through method of graded masking alarms, the invention lightens handling burden of BAM.
