# Prometheus Metrics

> Prometheus exposition endpoint for Porter metric-based autoscaling.

`ontora_livekit_session_demand` = waiting + in-flight interview sessions
in this region (same predicate as the KEDA design in deploy/keda/). The
livekit-agent-worker's autoscaler scales on it: one pod per ~10 sessions.
Worker-type services can't be scraped by Porter, so the web API serves the
gauge; a single indexed COUNT per scrape (~15-30s) is negligible load.
