TRACE-CMD-SPLIT(1)TRACE-CMD-SPLIT(1)NAME
trace-cmd-split - split a trace.dat file into smaller files
SYNOPSIS
trace-cmd split [OPTIONS] [start-time [end-time]]
DESCRIPTION
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.
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.
If *-p* is specified, then *-c* is automatically set.
-r
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.
-c
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.
