Trigger "Pending" state if no data or all values are null

Grafana Alerting
1

Hi,

due to a backup being run on one of our monitored machines, Grafana receives “No-Data” for one minute at a certain time every night.

Our normal alert is set to a 3m pending state. As far is know, “No-Data” alerts however will be send directly, without switching to pending state first.

If we switch “if no data or all values are null” to “Alerting”, will it also fire directly or go to pending first? Is there a way to set a “Pending” timeframe for “No-Data” alerts?

Thanks a lot and have a great day!
Simon

I had the exact same question. Did you figure out the details of this behavior @xmasterninni?

I guess I’ll give it a try.

Hi,
AFAIK (and tested), setting Alerting will be treated as breaching the threshold, so it would not fire immediately. That being said, the screen in the original post seems to be from a Grafana version from times I didn’t know what Grafana was :smile: In the recent versions (8+), the behavior I described stands. Make sure that there are a couple of evaluations in your pending period though. In Grafana 10.3 (or so) Keep Last State came back to life, which might also suit your case.
