perf-report - Read perf.data (created by perf record) and display the profile
perf report [-i <file> | --input=file]
This command displays the performance counter profile information recorded via perf record.
-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,order], --call-graph Display call chains using type, min percent threshold and order. 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. order can be either: - callee: callee based call graph. - caller: inverted caller based call graph. Default: fractal,0.5,callee. -G, --inverted alias for inverted caller based call graph. --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. -c, --cpu Only report samples for 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. Default is to report samples on all CPUs. -M, --disassembler-style= Set disassembler style for objdump. --source Interleave source code with assembly code. Enabled by default, disable with --no-source. --asm-raw Show raw instruction encoding of assembly instructions. --show-total-period Show a column with the sum of periods. -I, --show-info Display extended information about the perf.data file. This adds information which may be very large and thus may clutter the display. It currently includes: cpu and numa topology of the host system.
