Hi, I want to include these hostnames in my alert messages on Telegram. I created a label called HostName, leaving its value blank, and added it to the alert contact points. Here’s my alert:

{{ range .Alerts }}
:rotating_light: iLO Alert :rotating_light:
HostName: {{ .Labels.HostName }}
{{ end }}

However, I’m not getting the hostnames in the alerts, and I see this instead into Telegram message:

:rotating_light: iLO Alert :rotating_light:
HostName:

Can you guide me on how to solve this problem?"

you iterate over .Alerts which is a struct with two fields Firing and Resolved.
Try change your template to

{{ range .Alerts.Firing }}
:rotating_light: iLO Alert :rotating_light:
HostName: {{ .Labels.HostName }}
{{ end }}

@sasanaalem, I see the label HostName is returned by your Elastic query.

Query labels are also included in the .Labels property of the Alert in the notification template.

In this case, you don’t need to create a custom HostName label.

The issue may be that your custom HostName label is empty, which overwrites the value of the HostName query label. Removing the custom HostName label should resolve it.

More info in in the Label types documentation.
