How to change the link of the source field , when alertmanager sends alert

[karinh...@gmail.com]

Hello,

I have run prometheus and alertmanager in docker and have three different edition hwich I deploy with the same docker image.

How can I change the link of the source field, if the alertmanager sends an alert?

In the email_text.tmpl I can found this:

{{ end }} Source: {{ .GeneratorURL }}

Is it possible to change the link of the hostname but to keep the regular expression after the Hostname and Port?

Thanks in advance.

Hi,

It seems the only way is to use "--web.external-url=" argument.

I was looking for finding something in prometheus config so I can override it but I don't find.
