🔖 Feature description

If the PING monitor is set to a hostname rather then an IP and the DNS Server resolving Kumas request fails, services which are actually healty are marked as down immediately

Monitor Type = Ping

✔️ Solution

use the last known IP adress extracted from the ping reply of the monitor that responds a "Temporary failure in name resolution" for the next x tries instead of marking it as down immediately.

❓ Alternatives

Alternatively, a (UI) feature to add a "alternative IP" box when the user input in the [Hostname] field is everything but an IPv4 or IPv6

I like this idea, I would like to extend it that there should be a toggle that says: "Use last known good DNS:IP entry?"
IF DNS request fails, It can fall to the last known good nslookup reply.

I run a dual stack environment and would like to see UK try both v4 and v6 via DNS as a matter of course. Failing that, how about adding separate v4 and v6 ping options? As it is, v6 is used preferentially in Arch Linux so I have many systems that have status "down" when they are up.

I was going to request similar feature. I have my own DNS for my homelab, and recently I did some changes in DNS servers. My monitor suddenly started reporting failed services because of the DNS failure. Therefore I've got a lot of false notifications about failed services. Perhaps there should be a specific state like "unknown" when DNS resolver is not working and UK cannot TCP ping target server.
