[Observability] Ray Dashboard and Metrics aren't listing Driver by default #50097
Description
What happened + What you expected to happen
Recently, i've run into issue where my Driver was going was running out of heap memory, and there's surprisingly no direct way to observe it on any of Ray's observability surfaces
- Dashboard doesn't list driver as the process running on the head node
- Metrics don't list driver as standalone component (though it lists dashboard, agent, etc)
This creates a gap where driver isn't really covered by any of the existing surfaces.
Versions / Dependencies
2.41
Reproduction script
