PERF-TRACE(1)                     perf Manual                    PERF-TRACE(1)



NAME
       perf-trace - strace inspired tool

SYNOPSIS
       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.

       --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.
