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 order 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 output.dlt

EXIT STATUS

       Non zero is returned in case of failure.
