perf-trace - Read perf.data (created by perf record) and display trace output
|

SYNOPSIS

|
--------

|
|
'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.
|
|
|
|
'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.
