Data center operation and maintenance alarm information merging method and system

The invention discloses a data center operation and maintenance alarm information merging method and a system. The method comprises the following steps: collecting various operation and maintenance information and uniformly importing the information into a data center as original alarm information; extracting trunk alarm information and corresponding alarm detail data in the original alarm information by using a prefix tree; adopting FP-growth algorithm to extract association rules among alarm items in the original alarm information, and generating an alarm merging rule; compressing the alarm detail data based on the alarm merging rule to obtain merged alarm information; and pushing the merged alarm information to an alarm retransmission database according to a preset time interval and a deduplication strategy. According to the method, alarm analysis is carried out based on massive operation and maintenance information, trunk information of alarm data is gathered macroscopically, detail data is compressed acc
