Hi!

I am monitoring a service using the push monitor. Today, my service was down for 20 seconds and the uptime percentage dropped to less than 50%. After a few hours, it “recovered” to only 55%. I am wondering, how does the percentage gets calculated? I’d have expect to see it recover to 99% or something.

I attached a 24h log and also the events:

Up | 2021-11-14 18:44:20 | OK
Down | 2021-11-14 18:44:02 | No heartbeat in the time window
Up | 2021-11-14 00:34:11 | OK

Is there something I am missing?

Hi, I believe I’m having the same issue. My router restarted, so a few services had a downtime for a few minutes. The “Home Assistant” ones % went down by less than one. It’s a web monitor.

All the others are Push monitors and are down by much more than expected. Those are python sending heartbeats

Same with heartbeats sent from bash/curl

I’m on a non-docker 1.11.4 install on a medium hetzner VPS running Ubuntu 18.04.6 LTS.
