NAME
----
perf-evlist - List the event names in a perf.data file
SYNOPSIS
--------
[verse]
'perf evlist <options>'
DESCRIPTION
-----------
This command displays the names of events sampled in a perf.data file.
OPTIONS
-------
-i::
--input=::
Input file name. (default: perf.data)
SEE ALSO
--------
linkperf:perf-record[1], linkperf:perf-list[1],
linkperf:perf-report[1]
......@@ -112,6 +112,28 @@ OPTIONS
--debug-mode::
Do various checks like samples ordering and lost events.
-f::
--fields
Comma separated list of fields to print. Options are:
comm, tid, pid, time, cpu, event, trace, sym. Field
list must be prepended with the type, trace, sw or hw,
to indicate to which event type the field list applies.
e.g., -f sw:comm,tid,time,sym and -f trace:time,cpu,trace
-k::
--vmlinux=<file>::
vmlinux pathname
--kallsyms=<file>::
kallsyms pathname
--symfs=<directory>::
Look for files with symbols relative to this directory.
-G::
--hide-call-graph::
When printing symbols do not display call chain.
