Yeah, I get that but monitoring needs tend to diverge quite a bit depending on the use cases making detailed monitoring often need fair bit of flexibility, so I'm a bit skeptical about adding a fixed controller for that. I think a better approach may be implementing features which can make dynamic monitoring whether that's through bpf, drgn or plain tracepoints easier and more efficient. Thanks. -- tejun
