NAME

       dlt-sortbytimestamp - Re-order DLT Logging files according to message creation time and timestamp.

SYNOPSIS

       dlt-sortbytimestamp [-h] [-v] [-c] [-f filterfile] [-b number] [-e number] dltfile_in dltfile_out

DESCRIPTION

       By  default  messages  in DLT files are ordered according to the time the logger received them.  This can
       unhelpful when tracing a sequence of events on a busy multi-threaded/multi-core  system,  because  thread
       pre-emption combined with multiple processes attempting to log messages simultaneously means that the or‐
       der in which the messages are received may vary significantly from the order in which they were created.

       dlt-sortbytimestamp  is  able  to re-order a DLT input file’s messages according both their creation time
       and timestamp, and writes them to an output DLT file.

NOTE

       Use the *-b* and/or *-e* options to specify a range of messages within a single reboot cycle and all will
       be well.

       Hint: use dlt-viewer to ascertain the endpoints of the range in question.

OPTIONS

       -h     Display a short help text.

       -v     Verbose mode.  Repeat to give more information.

       -c     Count number of messages.

       -f     Enable filtering of messages.  Incompatible with range options.

       -b     First message to be handled.  Zero based index.

       -e     Last message to be handled.  Zero based index.

EXAMPLES

       Sort an entire file by message timestamp: dlt-sortbytimestamp input.dlt output.dlt

       Sort a specific range, e.g. from message 1,000,000 to message 1,500,000 from a file called input.dlt  and
       store  the  result  in a file called output.dlt: dlt-sortbytimestamp -b 1000000 -e 1500000 input.dlt out‐
       put.dlt

EXIT STATUS

       Non zero is returned in case of failure.
