perf-trace(1)
|
|
==============
|
|
|
|
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.
