6. Call me “Serverful Guy”
7. Today
9. eBPF does to Linux what JavaScript does to HTML. http://www.brendangregg.com/blog/2019-01-01/learn-ebpf-tracing.html
10. eBPF is so good at tracing/networking
11. Such as seccomp, perf, tc, XDP
12. We use Linux to do cloud-native stuff, so eBPF is effective
13. But eBPF byte codes are hard to write
14. BCC can create eBPF program in combination of a little C and Python/Lua
15. bpftrace(8) is a new dtrace
 having a flavor of eBPF
16. IO Visor is (also)
 a Linux Foundation Project
17. BTW:
 my hobby bonsai project mruby-bcc https://github.com/udzura/mruby-bcc/blob/master/example/usdt.rb
18. Demo of tracing in Kubernetes Pod https://medium.com/@calavera/spy-on-your-kubernetes-cluster-with-bpf-b09032bd1cdc
