I have installed Prometheus and Grafana on an AKS cluster using Helm, while setting up email alerting, there an error that states; “SMTP not configured, check your Grafana.ini config file’s [smtp] section” .
I will be very grateful for someone to help me and with a way forward to solve this issue.
Hi @kings620,
Welcome to the 
community support forums !!
The SMTP is enabled by default in the Grafana configuration. You need to enable it via Environmental variables to send out alerts.
Please have a look at this post which is similar to your question as it defines all the required ENV Variable parameters required to make it work.
Let us know if this helps.
