[iovisor-dev] bpftrace launched
G'Day, We've been working on wrapping up bpftrace for a while -- a high-level tracer for eBPF -- and we've now made the private repo public: https://github.com/iovisor/bpftrace Thanks Alastair Robertson for creating and developing this, and thanks to Willian Gaspar and Matheus Marchini for their recent contributions. And thanks to everyone who has been building the kernel eBPF, libbcc, and libbpf that bpftrace uses. Speaking of contributions, the bpftrace issue list still has many minor things to do, and help is appreciated! To learn bpftrace, there is a one-liners tutorial and a reference guide: - https://github.com/iovisor/bpftrace/blob/master/docs/tutorial_one_liners.md - https://github.com/iovisor/bpftrace/blob/master/docs/reference_guide.md Brendan -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.
