Patent ID: 8924642

Claim:
A monitoring record management method, wherein multiple monitoring records are stored in a memory, each monitoring record is used to monitor one or more chunks in a storage, and the monitoring record is a set of at least one monitoring parameter, and the method comprises: reading at least one monitoring parameter from monitoring records in the memory; for the read monitoring parameter, calculating a difference of monitoring parameters of a same type between different monitoring records; reading, from the memory, monitoring records between which each monitoring parameter difference meets a corresponding preset threshold, combining the read monitoring records and generating a combined monitoring record, wherein identities of monitored chunks are recorded in the combined monitoring record, and deleting, from the memory, the monitoring records that are combined, wherein a value of at least one monitoring parameter in the combined monitoring record is equal to a value of each monitoring parameter when all monitored chunks are viewed as one chunk; and writing the combined monitoring record into the memory, wherein the combined monitoring record is used to monitor chunks monitored by each monitoring record before the combination.
