- perf-data(1)
- ============
- NAME
- ----
- perf-data - Data file related processing
- SYNOPSIS
- --------
- [verse]
- 'perf data' [<common options>] <command> [<options>]",
- DESCRIPTION
- -----------
- Data file related processing.
- COMMANDS
- --------
- convert::
- Converts perf data file into another format.
- It's possible to set data-convert debug variable to get debug messages from conversion,
- like:
- perf --debug data-convert data convert ...
- OPTIONS for 'convert'
- ---------------------
- --to-ctf::
- Triggers the CTF conversion, specify the path of CTF data directory.
- --to-json::
- Triggers JSON conversion. Specify the JSON filename to output.
- --tod::
- Convert time to wall clock time.
- -i::
- Specify input perf data file path.
- -f::
- --force::
- Don't complain, do it.
- --time::
- Only convert samples within given time window: <start>,<stop>. Times
- have the format seconds.nanoseconds. If start is not given (i.e. time
- string is ',x.y') then analysis starts at the beginning of the file. If
- stop time is not given (i.e. time string is 'x.y,') then analysis goes
- to end of file. Multiple ranges can be separated by spaces, which
- requires the argument to be quoted e.g. --time "1234.567,1234.789 1235,"
- Also support time percent with multiple time ranges. Time string is
- 'a%/n,b%/m,...' or 'a%-b%,c%-%d,...'.
- For example:
- Select the second 10% time slice:
- perf data convert --to-json out.json --time 10%/2
- Select from 0% to 10% time slice:
- perf data convert --to-json out.json --time 0%-10%
- Select the first and second 10% time slices:
- perf data convert --to-json out.json --time 10%/1,10%/2
- Select from 0% to 10% and 30% to 40% slices:
- perf data convert --to-json out.json --time 0%-10%,30%-40%
- -v::
- --verbose::
- Be more verbose (show counter open errors, etc).
- --all::
- Convert all events, including non-sample events (comm, fork, ...), to output.
- Default is off, only convert samples.
