For now, can we skip printing when count is zero with a todo in the code explaining why? Also, if you don't mind opening an issue in rust-bcc - I want to take a deeper look into this. Please link it to this PR for reference. I will review the PR tomorrow. Thanks! |

Implements the iovisor's
syscount
code in rustOnly difference so far between the outputs is that it does not show counts/latency by process. They implemented it by reading
/proc/{pid}/comm
and I'm trying to figure out a way to do it with bpf only. e.g.BPF_HASH(pid, BPF_HASH(..))
Possible bug:
The bpf table in rust never seems to be empty. i.e. there would always be an entry with key=0 even after I call delete_all. And syscall=0 maps to
read
so you see the following whenever there are no actual values.
