Summary

  • Document UP_PROMETHEUS_INTERVAL / prometheus.interval: omitted is a 60s cache, 0 disables the cache so /metrics fetches live, and values below 15s warn but are not clamped.
  • Note in the FAQ that poller's cache interval is distinct from Prometheus scrape_interval.

Companion to unpoller/unpoller#1083.

Test plan

  • Confirm the Prometheus env table on the configuration page lists UP_PROMETHEUS_INTERVAL
  • Confirm the short-scrape FAQ mentions poller's prometheus.interval

Made with Cursor

Match the unpoller scrape-cache contract: omitted is 60s, 0 fetches
live, and sub-15s values warn instead of clamping.
