Hello, absent_over_time() Looks good. It should allow me to alert If metrics is Not available for 10min. This will not alert If system reboots.
If i use a query with Offset I think it would alert only AeS Long as the Offset still hast a value, eg Offset 10m i will get an Alarm For 10m but after that the "now" is the Same as the Offset. Will give it a try. Thanks!! Chris Siebenmann schrieb am Montag, 26.
