NAME

6       perf-report - Read perf.data (created by perf record) and display the
7       profile

SYNOPSIS

10       perf report [-i <file> | --input=file]
11

DESCRIPTION

13       This command displays the performance counter profile information
14       recorded via perf record.
15

OPTIONS

17       -i, --input=
18           Input file name. (default: perf.data)
19
20       -d, --dsos=
21           Only consider symbols in these dsos. CSV that understands
22           file://filename entries.
23
24       -n, --show-nr-samples
25           Show the number of samples for each symbol
26
27       -T, --threads
28           Show per-thread event counters
29
30       -C, --comms=
31           Only consider symbols in these comms. CSV that understands
32           file://filename entries.
33
34       -S, --symbols=
35           Only consider these symbols. CSV that understands file://filename
36           entries.
37
38       -s, --sort=
39           Sort by key(s): pid, comm, dso, symbol, parent.
40
41       -w, --field-width=
42           Force each column width to the provided list, for large terminal
43           readability.
44
45       -t, --field-separator=
46           Use a special separator character and don’t pad with spaces,
47           replacing all occurances of this separator in symbol names (and
48           other output) with a .  character, that thus it’s the only non
49           valid separator.
50
51       -g [type,min], --call-graph
52           Display callchains using type and min percent threshold. type can
53           be either:
54
55           ·   flat: single column, linear exposure of callchains.
56
57           ·   graph: use a graph tree, displaying absolute overhead rates.
58
59           ·   fractal: like graph, but displays relative rates. Each branch
60               of the tree is considered as a new profiled object.
61
62               Default: fractal,0.5.
