Please help with best alert rule for fast-ping checks

Hello @jozefrebjak,
I am also testing the fast-ping new feature. However, strangely I’m getting a lot of false alarms, alert still triggered when device status has changed to up and other problems. Please refer here for my help ticket.

Just wondering how it is going on your side? Have you put it on production? Is there any problems?

It would be very appreciated if you could share your experiences with me.
Thanks,
Roger
