Hi,

The portal offers a notification option for down time. I have a probe that is connected both over IPv4 and IPv6. The latter is through an IPv6 tunnel, which seems a bit flaky at times. I was hoping that the downtime notification would also hold for IPv6, but it turns out it doesn’t. Would it be possible that that be added?

Thanks, Jeroen.

Hi, Probes try to keep an opne connection to the infrastructure using either IPv4 or IPv6. As long as this connection is up, they are happy. If this connection goes down for more than 30 minutes, then this notification mechanism is triggered. It follows that flakyness of the "other" protocol is not detected by this mechanism -- and it would be difficult to add it without maintaining parallel sessions using both protocols. It's technically possible to detect some of this flakyness by looking at the (real-time) results supplied by the probe. I don't think it's a simple exercise though. Regards, Robert
