As with all metrics (scraped or created via recording rule) you need to be setting the scrape/interval to less than 5 minutes otherwise a metric will be marked as stale and not returned. In practice 2 minutes is the maximum sensible scrape interval, and while you could make it a bit longer for recording rules it still needs to be short enough to ensure there is never more than 5 minutes between points. -- You received this message because you are subscribed to the Google Groups "Prometheus Users" group.
