Selective logging and wheel of time for vehicle network logger system

A method for performing selective logging in a vehicle network logging system (VNLS), the method comprising:

• recording by a plurality of recorders data from data sources, the recorders generating from the recorded data data elements comprising a logstream, wherein each of the data elements comprises an interval of the recorded data and includes a timestamp indicative of a beginning time of the interval;
• generating by a trigger manager a snapshot in connection with a trigger received from a trigger control module, wherein the snapshot links to a first subset of the data elements containing data related to an event associated with the trigger;
• and
• periodically deleting by a flusher a second subset of the data elements comprising ones of the data elements that are outside a rolling hold time window associated with the logstream and that are not part of the first subset of the data elements,
• wherein the snapshot comprises one or more of an ID of the trigger associated with the snapshot, a priority of the trigger associated with the snapshot, a timestamp of the event associated with the snapshot, and a data size of the snapshot.

A non-transitory computer-readable memory device, which stores instructions for performing selective logging in a vehicle network logging system (VNLS), the instructions when executed by a processor cause the VNLS to:

• record by a plurality of recorders data from data sources, the recorders generating from the recorded data data elements comprising a logstream, wherein each of the data elements comprises an interval of the recorded data and includes a timestamp indicative of a beginning time of the interval;
• generate by a trigger manager a snapshot in connection with a trigger received from a trigger control module, wherein the snapshot links to a first subset of the data elements containing data related to an event associated with the trigger;
• and
• periodically delete by a flusher a second subset of the data elements comprising ones of the data elements that are outside a rolling hold time window associated with the logstream and that are not part of the first subset of the data elements,
• wherein the snapshot comprises one or more of an identifier of the trigger associated with the snapshot, a priority of the trigger associated with the snapshot, a timestamp of the event associated with the snapshot, and a data size of the snapshot.
