trace-cmd-split - split a trace.dat file into smaller files


trace-cmd split [OPTIONS] [start-time [end-time]]


The trace-cmd(1) split is used to break up a trace.dat into small files. The start-time specifies where the new file will start at. Using trace-cmd-report(1) and copying the time stamp given at a particular event, can be used as input for either start-time or end-time. The split will stop creating files when it reaches an event after end-time. If only the end-time is needed, use 0.0 as the start-time.

If start-time is left out, then the split will start at the beginning of the file. If end-time is left out, then split will continue to the end unless it meets one of the requirements specified by the options.


-i file

If this option is not specified, then the split command will look for the file named trace.dat. This options will allow the reading of another file other than trace.dat.

-o file

By default, the split command will use the input file name as a basis of where to write the split files. The output file will be the input file with an attached '.#\' to the end: trace.dat.1, trace.dat.2, etc.
 This option will change the name of the base file used.
 -o file  will create file.1, file.2, etc.

-s seconds

This specifies how many seconds should be recorded before the new file should stop.

-m milliseconds

This specifies how many milliseconds should be recorded before the new file should stop.

-u microseconds

This specifies how many microseconds should be recorded before the new file should stop.

-e events

This specifies how many events should be recorded before the new file should stop.

-p pages

This specifies the number of pages that should be recorded before the new file should stop.
 Note: only one of *-p*, *-e*, *-u*, *-m*, *-s* may be specified at a time.


This option causes the break up to repeat until end-time is reached (or end of the input if end-time is not specified).
 trace-cmd split -r -e 10000
 This will break up trace.dat into several smaller files, each with at most
 10,000 events in it.


This option causes the above break up to be per CPU.
 trace-cmd split -c -p 10
 This will create a file that has 10 pages per each CPU from the input.
