How do I add values from my alert query as a label? I tried

value:{{value}}

but that did not work. Is there any another way to display the values in the alert being sent?

we support both go template and $labels or $value notations like prometheus. example: {{.Labels.serviceName}} {{$labels.serviceName}} for value try {{$value}} the result of alert query will be populated in value

Where does this go? In the alert channel configuration?

when you create alert rule. you can see labels section.

Got it. Thank you!
