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
