EMail Alerts Subject

[danielesalvigni]

Hello Folk,
I had the following code implemented under

Alerting → Contact Points (Grafana as Alertmanager) → EMail → Subject

{{ if eq .Status “firing” }} [Alerting] {{index .CommonLabels “alertname” }} {{end}} {{ if gt (.Alerts.Resolved | len) 0 }} [OK] {{index .CommonLabels “alertname”}} {{end}}

It stopped to work.
I tried to simplify and I came to:

{{ if .Alerts.Firing }}[Alerting] Fire ON {{ .Alerts.EntityName }} {{ end }} {{ if .Alerts.Resolved }}[OK] Fire OFF {{ .Alerts.EntityName }} {{ end }}

But this return the following outcome:
" [Alerting] Fire ON [{firing map[EntityName:XXX alertname:XXX grafana_folder:OPS API Dashboard Alerts - QFqiNzJMk rule_id:XXX] map[Rule ID:XXX] 2023-06-19 09:43:00 +0000 UTC 0001-01-01 00:00:00 +0000 UTC https://XXX/view?orgId=1 XXX https:/XXX/alerting/silence/new?alertmanager=grafana&matcher=EntityName%3DXXX&matcher=alertname%3DXXX&matcher=grafana_folder%3DOPS+API+Dashboard+Alerts±+XXX&matcher=rule_id%3DXXX https://XXX?orgId=1 https://XXX?orgId=1&viewPanel=68 map[C:122.6 D:1] [ var=‘C’ labels={EntityName=XXX} value=122.6 ], [ var=‘D’ labels={EntityName=XXX} value=1 ] }]"

I replaced with XXX internal names. Can you suggest and easy solution? I checked in documentation but it seems that there is no answer to a Simple question like “setting up dynamically the title of the alert”…

hi @danielesalvigni

what is your version of Grafana, on what platform is it running, and what data source does your alert query?

[danielesalvigni]

Hello,
version 9.5.2, as docker container directly from docker HUB, and I am running it as is into an app service in Azure.

{{ .Alerts.EntityName }}

Alerts is a list. It doesn’t have “EntityName” element. So you need to loop through Alerts and retrieve value of “EntityName” from each individual Alert. (even if Alerts have just a single Alert).

It’s also possible that you have “EntityName” in GroupLabels or CommonLabels depending on how you configured alert grouping.

(I might be completely wrong )

The most likely reason this stopped working is because the grouping changed in the notification policy. If alertname is no longer in the group by it won’t be a common label.

Can you explain how/where to fix it?

[georgerobinson]

Make sure alertname is in Group by for your notification policies, as can be seen here:
