Modifying Grafana Email notification template

Hello,

I’d like to create a notification template similar to the default email notification template for Alerting, however unsure how to go about this and the code is not so forthcoming. Do I need to write MJML in the template? How do I achieve an output that does not include all labels and all values?

For example, in the below image I would like my alert to show a particular label=value per instance of MySQL that is out of sync, and I’d like to get rid of alertname and grafana_folder labels

Do you have any Grafana doc, where is mentioned that MJML is supported?

No, I was looking through the grafana code however and noticed some mjml email templates and don’t understand how it fits into the equation.

Generally, that’s not supported/recommend/documented. Of course you can be on your own and fork&maintain own Grafana fork for that.

Oficial way is to create own notification template, which will be used by used contact point:
