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 = 2

               List 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.
