       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 .

                   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

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.
