SYNOPSIS
perf [--version] [--help] [OPTIONS] COMMAND [ARGS]
OPTIONS
-h, --help
Run perf help command.
-v, --version
Display perf version.
-vv
Print the compiled-in status of libraries.
--exec-path
Display or set exec path.
--html-path
Display html documentation path.
-p, --paginate
Set up pager.
--no-pager
Do not set pager.
--buildid-dir
Setup buildid cache directory. It has higher priority than buildid.dir config file option.
--list-cmds
List the most commonly used perf commands.
--list-opts
List available perf options.
--debugfs-dir
Set debugfs directory or set environment variable PERF_DEBUGFS_DIR.
--debug
Setup debug variable (see list below) in value range (0, 10). Use like: --debug verbose # sets verbose = 1 --debug verbose=2 # sets verbose = 2List of debug variables allowed to set: verbose - general debug messages ordered-events - ordered events object debug messages data-convert - data convert command debug messages stderr - write debug output (option -v) to stderr in browser mode perf-event-open - Print perf_event_open() arguments and return value kmaps - Print kernel and module maps (perf script and perf report without browser)
--debug-file
Write debug output to a specified file.
DESCRIPTION
Performance counters for Linux are a new kernel-based subsystem that provide a framework for all things performance analysis. It covers hardware level (CPU/PMU, Performance Monitoring Unit) features and software features (software counters, tracepoints) as well.
