| help |
| bpftrace is a high-level tracing language for Linux enhanced |
| Berkeley Packet Filter (eBPF) available in recent Linux |
| kernels (4.x). |
| |
| bpftrace uses LLVM as a backend to compile scripts to |
| BPF-bytecode and makes use of BCC for interacting with the |
| Linux BPF system, as well as existing Linux tracing |
| capabilities: kernel dynamic tracing (kprobes), user-level |
| dynamic tracing (uprobes), and tracepoints. The bpftrace |
| language is inspired by awk and C, and predecessor tracers |
| such as DTrace and SystemTap. |
| |
| It's highly recommended to NOT strip bpftrace binary. |
| To do so, add "bpftrace" to BR2_STRIP_EXCLUDE_FILES. |
