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
-o file
This option will change the name of the base file used.
-o file will create file.1, file.2, etc.
-s seconds
-m milliseconds
-u microseconds
-e events
-p pages
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
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
trace-cmd split -c -p 10
This will create a file that has 10 pages per each CPU from the input.
-C cpu
trace-cmd split -C 1
This will split out all the events for cpu 1 in the file.
