-=============
-
-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
--------
-
--a::
---all-cpus::
- System-wide collection from all CPUs.
-
--e::
---expr::
- List of events to show, currently only syscall names.
- Prefixing with ! shows all syscalls but the ones specified. You may
- need to escape it.
-
--o::
---output=::
- Output file name.
-
--p::
---pid=::
- Record events on existing process ID (comma separated list).
-
--t::
---tid=::
- Record events on existing thread ID (comma separated list).
-
--u::
---uid=::
- Record events in threads owned by uid. Name or number.
-
--v::
---verbose=::
- Verbosity level.
-
--i::
---no-inherit::
- Child tasks do not inherit counters.
-
--m::
---mmap-pages=::
- Number of mmap data pages. Must be a power of two.
-
--C::
---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.
-
--i
---input
- Process events from a given perf data file.
