Epic: LFC-aware scaling follow-ups #1011

Open sharnoff opened 4 months ago

sharnoff commented 4 months ago

Motivation

With #1003, we have some minor known issues with the LFC-aware scaling implementation. These aren't enough to block merging, but we'd like to fix them eventually.

Tasks

- [ ] Don't require exact 1-minute intervals for working set size metrics
- [ ] Trigger "stuck VMs" if core state is degraded (e.g., missing LFC metrics)
- [x] Resurrect #737
- [ ] Make `lfcToMemoryRatio` required (or, emit warning if not set per VM)
