Description

@justinvyu shipped #53191 which adds an endpoint to fetch kineto traces from a particular process running torch. I believe the Anyscale product exposes this functionality in its Ray Train + Data specific pages. I want to explore exposing this functionality in the open source dashboard.

Ideally we'd be able to add it as an option in the "actions" column but for a lot of setups it won't be applicable / useful.

  1. Dynolog is a prereq. Users would need to install this.
  2. This only works for processes running torch
  3. Even with processes running torch, the user need to manually set the environment flag KINETO_USE_DAEMON.

Is this a blocker to adding it as an always there option? Is there a better screen to add this to?
