Prometheus – what’s new and what’s next?
summary
Prometheus now ships a six-week release cadence, persists alert “for” state across restarts so long running alerts fire after a reboot, and adds retention by size (storage.retention.size) alongside time retention to avoid full disks. Query safety uses a max_samples default cap and max_concurrency to prevent memory explosions, subqueries work with the new : syntax, a target metadata HTTP API surfaces help strings and metric types, OpenMetrics adoption progresses, and TLS serving for scrape/endpoints is under active development.
