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.

       -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.

NAME

       tapset::perf - systemtap perf probe points

DESCRIPTION

       This  family  of probe points is used to probe "perf events" on suitably configured kernels (2.6.33+).  It contains a number of aliases for
       the ABI-specified event type/config tuples.

       The default sampling interval of the translator(1000000) is not overridden, so some of these probe points may fire very infrequently.  Use
       the lower level perf.type(AA).config(BB).sample(CC) probe point if this is a problem.

       perf.hw.*
	      A  variety of hardware events, as generalized by the kernel.  These generally require running on bare hardware with selected proces-
	      sors.
	      probe perf.hw.cpu_cycles
	      probe perf.hw.instructions
	      probe perf.hw.cache_references
	      probe perf.hw.cache_misses
	      probe perf.hw.branch_instructions
	      probe perf.hw.branch_misses
	      probe perf.hw.bus_cycles

       perf.sw.*
	      Special "software" events provided by the kernel.  These sometimes work in virtualized environments and with more  processor  archi-
	      tectures.
	      probe perf.sw.cpu_clock
	      probe perf.sw.task_clock
	      probe perf.sw.page_faults
	      probe perf.sw.context_switches
	      probe perf.sw.cpu_migrations
	      probe perf.sw.page_faults_min
	      probe perf.sw.page_faults_maj
	      probe perf.sw.alignment_faults
	      probe perf.sw.emulation_faults

       perf.hw_cache.TYPE.ACCESS.RESULT
	      Hardware cache events, where available.  A subset of the following cartesian product may be available:
	      probe perf.hw_cache.l1d.*.*
	      probe perf.hw_cache.l1i.*.*
	      probe perf.hw_cache.ll.*.*
	      probe perf.hw_cache.dtlb.*.*
	      probe perf.hw_cache.itlb.*.*
	      probe perf.hw_cache.bpu.*.*

	      probe perf.hw_cache.*.read.*
	      probe perf.hw_cache.*.write.*
	      probe perf.hw_cache.*.prefetch.*

	      probe perf.hw_cache.*.*.access
	      probe perf.hw_cache.*.*.miss
