NAME
bpftool-perf - tool for inspection of perf related bpf prog attachments

SYNOPSIS
        bpftool [OPTIONS] perf COMMAND

        OPTIONS := { [{ -j | --json }] [{ -p | --pretty }] }

        COMMANDS := { show | list | help }

PERF COMMANDS
bpftool perf { show | list }
bpftool perf help

DESCRIPTION

            bpftool perf { show | list }
                List all raw_tracepoint, tracepoint, kprobe attachment in the system.

                Output will start with process id and file descriptor in that process, followed by bpf program id, attachment information, and attachment point. The attachment point for raw_tracepoint/tracepoint is the trace probe name. The attachment point for k[ret]probe is either symbol name and offset, or a kernel virtual address. The attachment point for u[ret]probe is the file name and the file offset.

            bpftool perf help
                Print short help message.

OPTIONS

            -h, --help
                Print short generic help message (similar to bpftool help).

            -V, --version
                Print version number (similar to bpftool version).

            -j, --json
                Generate JSON output. For commands that cannot produce JSON, this option has no effect.

            -p, --pretty
                Generate human-readable JSON output. Implies -j.

            -d, --debug
                Print all logs available from libbpf, including debug-level information.

EXAMPLES
# bpftool perf

        pid 21711  fd 5: prog_id 5  kprobe  func __x64_sys_write  offset 0
        pid 21765  fd 5: prog_id 7  kretprobe  func __x64_sys_nanosleep  offset 0
        pid 21767  fd 5: prog_id 8  tracepoint  sys_enter_nanosleep
        pid 21800  fd 5: prog_id 9  uprobe  filename /home/yhs/a.out  offset 1159
