- perf-trace(1)
- =============
- NAME
- ----
- perf-trace - strace inspired tool
- SYNOPSIS
- --------
- [verse]
- 'perf trace'
- DESCRIPTION
- -----------
- This command will show the events associated with the target, initially
- syscalls, but other system events like pagefaults, task lifetime events,
- scheduling events, etc.
- Initially this is a live mode only tool, but eventually will work with
- perf.data files like the other tools, allowing a detached 'record' from
- analysis phases.
- OPTIONS
- -------
- --all-cpus::
- System-wide collection from all CPUs.
- -e::
- --expr::
- List of events to show, currently only syscall names.
- -o::
- --output=::
- Output file name.
- -p::
- --pid=::
- Record events on existing process ID (comma separated list).
- --tid=::
- Record events on existing thread ID (comma separated list).
- --uid=::
- Record events in threads owned by uid. Name or number.
- --no-inherit::
- Child tasks do not inherit counters.
- --mmap-pages=::
- Number of mmap data pages. Must be a power of two.
- --cpu::
- Collect samples only on the list of CPUs provided. Multiple CPUs can be provided as a
- comma-separated list with no space: 0,1. Ranges of CPUs are specified with -: 0-2.
- In per-thread mode with inheritance mode on (default), Events are captured only when
- the thread executes on the designated CPUs. Default is to monitor all CPUs.
- --duration:
- Show only events that had a duration greater than N.M ms.
- --sched:
- Accrue thread runtime and provide a summary at the end of the session.
