1. A system, comprising:

  • a tag, comprising;

    a set of accelerometers configured to detect acceleration of the tag along multiple axes;

    a processor to process acceleration measurements provided by the set of accelerometers, wherein processing by the processor comprises;

    sorting the acceleration measurements according to direction and degree of acceleration detected by the set of accelerometers, setting a use start time based on the acceleration detected exceeding a predetermined threshold after initialization of the tag; and

    setting a use end time based on the acceleration detected exceeding the predetermined threshold and the use start time being set;

    a memory to store results of the processing of the processor; and

    a transceiver configured for wireless communication;

    wherein the tag is configured for attachment to an exterior surface of a drill string;

    wherein the use start time specifies a time at which a downhole component to which the tag is attached is put into a service, and the use end time specifies a time at which the downhole component to which the tag is attached is no longer in the service;

    wherein the transceiver is configured to transfer the acceleration measurements via a communication link including long wavelength inductive transmission to a facility that analyzes operation of the downhole component.
