NAME

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

SYNOPSIS

       bpftool [OPTIONS] perf COMMAND

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

       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 help message (similar to bpftool help).

       -V, --version
              Print bpftool's version number (similar to bpftool version), the number of the libbpf  version  in
              use, and optional features that were included when bpftool was compiled. Optional features include
              linking against LLVM or libbfd to provide the disassembler for JIT-ted programs (bpftool prog dump
              jited)  and  usage  of  BPF  skeletons  (some  features  like bpftool prog profile or showing pids
              associated to BPF objects may rely on it).

       -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, even debug-level information. This includes logs from libbpf as well  as
              from the verifier, when attempting to load programs.

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

       # bpftool -j perf
