i have upgrade grafana version to v9.3.1, why i got many alert with alert no value
Hi! These are
DatasourceNoData alerts, and happen when Grafana queries the datasource but there is no data for the time range. If this happens often then you will want to either increase the frequency that data is collected in your datasource, or increase the time range of the query.
Hi @georgerobinson how long is the ideal time (time range), especially for the windows server that I monitor?
How often does the datasource collect data from these servers? In Prometheus, for example, the default scrape interval is 15 seconds.
i set like this, but still got many alert no value
Is there any suggestion so that I don’t get the no value alert?
Hi! Did you see my previous reply? If you know the answer to this it will help us fix your No Data issue.

yes i have tried it, but still getting novalue alert
anyway, this case resolved with silences
Silence generally stops sending alert at all. Do you receive any alerts from crossing thresholds?
