Hi,
I am able to set time series graph and my alert rules has been set.
I have checked alerts from alerts menu and test alerts sent out in slack channel.
On test rule it say alerting, but no alerts is being received.
Kindly check attached screenshots here with.
what version of grafana are you running? and are you using the legacy alerting platform or the new unified alerting platform that debuted in v8 and became the default in v9?
