PERF-REPORT(1) perf Manual PERF-REPORT(1)NAMEperf-report - Read perf.data (created by perf record) and display the
profile
SYNOPSIS
perf report [-i <file> | --input=file]
DESCRIPTION
This command displays the performance counter profile information
recorded via perf record.
OPTIONS-i, --input=
Input file name. (default: perf.data)
-v, --verbose
Be more verbose. (show symbol address, etc)
-d, --dsos=
Only consider symbols in these dsos. CSV that understands
file://filename entries.
-n, --show-nr-samples
Show the number of samples for each symbol
--showcpuutilization
Show sample percentage for different cpu modes.
-T, --threads
Show per-thread event counters
-C, --comms=
Only consider symbols in these comms. CSV that understands
file://filename entries.
-S, --symbols=
Only consider these symbols. CSV that understands file://filename
entries.
-U, --hide-unresolved
Only display entries resolved to a symbol.
-s, --sort=
Sort by key(s): pid, comm, dso, symbol, parent.
-p, --parent=<regex>
regex filter to identify parent, see: --sort parent
-x, --exclude-other
Only display entries with parent-match.
-w, --column-widths=<width[,width...]>
Force each column width to the provided list, for large terminal
readability.
-t, --field-separator=
Use a special separator character and don't pad with spaces,
replacing all occurrences of this separator in symbol names (and
other output) with a . character, that thus it's the only non
valid separator.
-D, --dump-raw-trace
Dump raw trace in ASCII.
-g [type,min], --call-graph
Display call chains using type and min percent threshold. type can
be either:
· flat: single column, linear exposure of call chains.
· graph: use a graph tree, displaying absolute overhead rates.
· fractal: like graph, but displays relative rates. Each branch
of the tree is considered as a new profiled object. Default:
fractal,0.5.
--pretty=<key>
Pretty printing style. key: normal, raw
--stdio Use the stdio interface.
--tui Use the TUI interface,
that is integrated with
annotate and allows
zooming into DSOs or
threads, among other
features. Use of --tui
requires a tty, if one is
not present, as when
piping to other commands,
the stdio interface is
used.
-k, --vmlinux=<file>
vmlinux pathname
--kallsyms=<file>
kallsyms pathname
-m, --modules
Load module symbols. WARNING: This should only be used with -k and
a LIVE kernel.
-f, --force
Don't complain, do it.
--symfs=<directory>
Look for files with symbols relative to this directory.
