NAMEperf-report - Read perf.data (created by perf record) and display the profile
perf report [-i <file> | --input=file]
- Input file name. (default: perf.data unless stdin is a fifo)
- Be more verbose. (show symbol address, etc)
- Only consider symbols in these dsos. CSV that understands m[blue]file://filenamem entries.
- Show the number of samples for each symbol
- Show sample percentage for different cpu modes.
- Show per-thread event counters
- Only consider symbols in these comms. CSV that understands m[blue]file://filenamem entries.
- Only consider these symbols. CSV that understands m[blue]file://filenamem entries.
- Only display entries resolved to a symbol.
- Sort by key(s): pid, comm, dso, symbol, parent.
- regex filter to identify parent, see: --sort parent
- Only display entries with parent-match.
- Force each column width to the provided list, for large terminal readability.
- Use a special separator character and doncqt pad with spaces, replacing all occurrences of this separator in symbol names (and other output) with a . character, that thus itcqs the only non valid separator.
- Dump raw trace in ASCII.
-g [type,min[,limit],order], --call-graph
Display call chains using type, min percent threshold, optional print limit 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.
- alias for inverted caller based call graph.
- Pretty printing style. key: normal, raw
- Use the stdio interface.
- 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.
- vmlinux pathname
- kallsyms pathname
- Load module symbols. WARNING: This should only be used with -k and a LIVE kernel.
- Doncqt complain, do it.
- Look for files with symbols relative to this directory.
- 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.
- Set disassembler style for objdump.
- Interleave source code with assembly code. Enabled by default, disable with --no-source.
- Show raw instruction encoding of assembly instructions.
- Show a column with the sum of periods.
- 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.
