Hello. I created panel that shows net traffic. It is grouped by host (i have nearly hundred of hosts).
Then I created alerting with this rule:
Which works as expected, but I would also like to see alerting when one of hundred hosts stops sending data (e.g. Telegraf crashes, or server is down). I googled about it a lot, but it seems that it is not possible (it only alerts when all hosts stop sending data, not one). Question: Is it possible to do this type of alerting right from Grafana?
