Grafana Alerting
1

Tried in many possible ways. unable to send email alerts from grafana though my smtp configurations are correct!!!

logger=alerting.notifier.email t=2022-12-26T13:48:57.595540175+03:00 level=error msg="Missing receiver
logger=alerting.notifier.email t=2022-12-26T13:48:57.595875127+03:00 level=error msg="Missing group labels"

These are the error logs i have got while trying to send a test alert from grafana.
Could anyone please help on this.

I have attached my smtp configuration as well, here.

smtp:
enabled: true
host: smtp.gmail.com:587
user: “alertgrafan@gmail.com”
password: “**********”
skip_verify: true
from_address: “*****”
from_name: “Grafana”
startTLS_policy: “NoStartTLS”

Have you tried using Contact point testing? If you use the Test button, can you receive emails?

It is only information log.

Did someone get any response? I’m getting the same error when trying to send a Test email notification from my RHEL 8 (Linux) sever. Installed Prometheus and Grafana as services (instead of using Docker images).
