|
OPTIONS
|
|
-------
|
|
-i::
|
|
--input=::
|
|
Input file name. (default: perf.data)
|
|
|
|
-v::
|
|
--verbose::
|
|
Be more verbose. (show symbol address, etc)
|
|
|
|
-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
|
|
|
|
--showcpuutilization::
|
|
Show sample percentage for different cpu modes.
|
|
|
|
-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.
|
|
|
|
-U::
|
|
--hide-unresolved::
|
|
Only display entries resolved to a symbol.
|
|
|
|
-s::
|
|
--sort=::
|
|
Sort by key(s): pid, comm, dso, symbol, parent.
|
|
|
|
-p::
|
|
--parent=<regex>::
|
|
regex filter to identify parent, see: '--sort parent'
|
|
|
|
-x::
|
|
--exclude-other::
|
|
Only display entries with parent-match.
|
|
|
|
-w::
|
|
--column-widths=<width[,width...]>::
|
|
Force each column width to the provided list, for large terminal
|
|
readability.
|
|
|
|
-t::
|
|
--field-separator=::
|
|
|
|
Use a special separator character and don't pad with spaces, replacing
|
|
all occurrences of this separator in symbol names (and other output)
|
|
with a '.' character, that thus it's the only non valid separator.
|
|
|
|
-D::
|
|
--dump-raw-trace::
|
|
Dump raw trace in ASCII.
|
|
|
|
-g [type,min]::
|
|
--call-graph::
|
|
Display call chains using type and min percent threshold.
|
|
type can be either:
|
|
- flat: single column, linear exposure of call chains.
|
|
- 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.
|
|
|
|
--pretty=<key>::
|
|
Pretty printing style. key: normal, raw
|
|
|
|
--stdio:: Use the stdio interface.
|
|
|
|
--tui:: Use the TUI interface, that is integrated with annotate and allows
|
|
zooming into DSOs or threads, among other features. Use of --tui
|
|
requires a tty, if one is not present, as when piping to other
|
|
commands, the stdio interface is used.
|
|
|
|
-k::
|
|
--vmlinux=<file>::
|
|
vmlinux pathname
|
|
|
|
--kallsyms=<file>::
|
|
kallsyms pathname
|
|
|
|
-m::
|
|
--modules::
|
