Hi Abhinav,
I'm having trouble reading the labels clearly, I have to admit. Still, this looks like a great start on "core" op processing.
I'm unsure of your available time. It would be super to work horizontally across more ops. It also makes sense to go deeper--but especially, to be able to jump across (I think) two domains that are off the left and right edges. To the left, it seems you can go some ways into the HTTP front-end (in that direction, I think we care about Beast and maybe not Civetweb so much). Meanwhile, to the right, most ops are pushing down into Ceph RADOS ops, and it would be particularly nice to trace across RGW high-level ops, into the underlying RADOS ops that work against the Ceph cluster.
In fine, nice work.
Matt
