       ieee        IEEE OUI Identifier is  the  Organization  Unique  Identifier  (OUI)  for  the
                   controller vendor that is able to interpret the data.

       hostdgn     Telemetry Host-Initiated Data Generation Number is a value that is incremented
                   each time the host initiates a capture of its internal controller state in the
                   controller .

       ctrlavail   Telemetry Controller-Initiated Data Available, if cleared, then the controller
                   telemetry log does not contain saved internal controller state. If this  field
                   is  set to 1h, the controller log contains saved internal controller state. If
                   this field is set to 1h, the data will be latched until the host  releases  it
                   by reading the log with RAE cleared.

       ctrldgn     Telemetry  Controller-Initiated  Data  Generation  Number  is  a value that is
                   incremented each time the controller  initiates  a  capture  of  its  internal
                   controller state in the controller .

       rsnident    Reason  Identifiers  a vendor specific identifier that describes the operating
                   conditions of the controller at the time of capture.

       data_area   Telemetry data blocks, vendor specific information data.

Description

       This log consists of a header describing the log and zero or more Telemetry  Data  Blocks.
       All  Telemetry  Data  Blocks  are  NVME_LOG_TELEM_BLOCK_SIZE, 512 bytes, in size. This log
       captures the controller’s internal state.
