fix: tune vmsingle resource limits and query settings#1494
Merged
Conversation
- remove explicit search.maxUniqueTimeseries cap (600k) to let vm auto-calculate (~4.3m with 32gi) - add search.logSlowQueryDuration for query observability - bump vmsingle memory from 8gi to 32gi with proper requests - add cpu/memory requests for both vmsingle and vmagent - remove cpu limit on vmsingle to allow unbounded burst
