Getting an alarm upon one failed request can be rather annoying. In most cases any issues on our systems resolve automatically, I’d still like to know, but an email would suffice. I don’t want push notifications at 3AM because of one lost HTTP request or heartbeat, sometimes they just get caught by some other system (like yesterday where UptimeRobot claimed a 503 on our systems, but there was no such error in any of the applicable logs. Had UR rechecked a minute later, there would be nothing. Making a check every three minutes or setting the delay to 60 seconds does not really give me what I want. Our burglar alarm technician calls this a “double knock” this prevents the guard from being called due to a single bug hovering in front of a sensor.

Hey, thanks for the feedback. Could you share a bit more about why the current delay feature doesn’t work for your case? For example, with a 30-second interval and a 1-minute delay, the monitor has to fail twice (1 minute total) before triggering an alert.
