Claim 8:
9. A non-transitory computer-readable medium configured to store computer logic having instructions that, when executed, cause one or more processing devices to:
obtain Performance Monitoring (PM) data during a current Measurement Interval of an ongoing PM session in accordance with the Metro Ethernet Forum (MEF) 35.1 standard, wherein the PM data is configured to be locally stored as a current dataset to be reported at the end of the current Measurement Interval for storage in a history database,
following an interruption event that interrupts at least the current Measurement Interval, detect a recommencement event that clears the interruption event and allows a PM session to resume,
determine a number of Measurement Intervals affected by the interruption event based on an end time of a last-reported Measurement Interval, and
insert the number of affected Measurement Intervals into the history database after the last-reported Measurement Interval,
wherein each of the Measurement Intervals includes PM data obtained during a predetermined time period, and wherein an end time of one of a particular Measurement Interval aligns with a start time of a subsequent Measurement Interval to eliminate gaps in the history database, and wherein the instructions further cause the one or more processing devices to set a suspect flag associated with each of the affected Measurement Intervals.
