22 Commits • 14 Features
Dec 1, 2024December 2024 delivered strong improvements in telemetry, UI visibility, system/resource management, and CI tooling, driving higher reliability, better observability, and faster incident response. Telemetry enhancements added memory usage timelines, along with memory/disk I/O timelines and expanded vmstorage metrics to support capacity planning and troubleshooting. UI now renders platform overrides for easier environmental configuration review. System and caching refinements included applying cgroup settings in the app and using cache keys with write caps to improve stability under load. CI/tooling and workspace hygiene were improved with an updated Bazelisk in the CI runner and more precise Firecracker workspace outputs, reducing CI noise. Reliability and diagnostics gained through better ExecuteResponse handling for expired responses, a new response JSON file flag, and additional logs for config parsing and missing group_id, enabling faster diagnosis.
