dlt-sortbytimestamp [-h] [-v] [-c] [-f filterfile] [-b number] [-e number] dltfile_in dltfile_out
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.
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.
Display a short help text.
Verbose mode. Repeat to give more information.
Count number of messages.
Enable filtering of messages. Incompatible with range options.
First message to be handled. Zero based index.
Last message to be handled. Zero based index.
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
Non zero is returned in case of failure.
