Email Subject for alerts

[sri L]

Hi all,

I want to add a label name in subject header. This is not a common label which we generally defined under target level. The label "name" is coming in metrics only and i want to see that "name" in email subject. Currently iam using this header value
[{{ .Status | toUpper }}] {{.CommonLabels.app_name}} {{.CommonLabels.hostname}}

can anyone please suggest here

Thanks
