Method, device, and computer program product for processing system latency

An electronic device, comprising:

• a processor;
• and
• a memory coupled to the processor having instructions stored therein which, when executed by the processor, cause the processor to perform actions, the actions comprising:
• obtaining a group of records in a system for a group of data persistence operations of a particular type, wherein each record in the group of records comprises a group of metrics for a group of states of the system within a predetermined period when each data persistence operation occurs;
• estimating a group of estimated latencies of the group of data persistence operations based on the group of records;
• determining corresponding contributions of each state in the group of states to latencies of the group of data persistence operations based on the group of records and the group of estimated latencies;
• and
• determining one or more states from the group of states based on the corresponding contributions.

A non-transitory computer-readable medium having instructions stored therein, which when executed, by a processor, cause the processor to perform actions, the actions comprising:

• obtaining a group of records in a system for a group of data persistence operations of a particular type, wherein each record in the group of records comprises a group of metrics for a group of states of the system within a predetermined period when each data persistence operation occurs;
• estimating a group of estimated latencies in the group of data persistence operations based on the group of records:
• determining corresponding contributions of each state in the group of states to latencies of the group of data persistence operations based on the group of records and the group of estimated latencies;
• and
• determining one or more states from the group of states based on the corresponding contributions.
