## NAME

perf-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)

\-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 -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.

\-w, --field-width=

\-t, --field-separator=

Use a special separator character and don’t pad with spaces, replacing all occurances of this separator in symbol names (and other output) with a *.* character, that thus it’s the only non valid separator.

- \-g \[type,min\], --call-graph

  Display callchains using type and min percent threshold. type can be either:

  • flat: single column, linear exposure of callchains.

  • 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.
