-NAME
-----
-perf-trace - Read perf.data (created by perf record) and display trace output
-
-SYNOPSIS
---------
-[verse]
-'perf trace' {record <script> | report <script> [args] }
-
-DESCRIPTION
------------
-This command reads the input file and displays the trace recorded.
-
-There are several variants of perf trace:
-
- 'perf trace' to see a detailed trace of the workload that was
- recorded.
-
- You can also run a set of pre-canned scripts that aggregate and
- summarize the raw trace data in various ways (the list of scripts is
- available via 'perf trace -l'). The following variants allow you to
- record and run those scripts:
-
- 'perf trace record <script>' to record the events required for 'perf
- trace report'. <script> is the name displayed in the output of
- 'perf trace --list' i.e. the actual script name minus any language
- extension.
-
- 'perf trace report <script>' to run and display the results of
- <script>. <script> is the name displayed in the output of 'perf
- trace --list' i.e. the actual script name minus any language
- extension. The perf.data output from a previous run of 'perf trace
- record <script>' is used and should be present for this command to
- succeed.
-
- See the 'SEE ALSO' section for links to language-specific
- information on how to write and run your own trace scripts.
