- :Manual section: 8
- 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**.
- 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
