Ah right: at the very top level you must specify a catch-all receiver (in
case no route matches). At lower levels in the tree you don't need to.
So just include one:
route:
receiver: send_mail # just to keep alertmanager happy, this will never
be used
routes:
- receiver: send_email
continue: true
- receiver: send_email2
> is it possible to have just one send_email reciever configured for two
email addresses?
Yes, as I showed in my first response
<https://groups.google.com/g/prometheus-users/c/i0TwbBrlp7o/m/4X6bJsSNAAAJ>.
receivers:
- name: send_email
email_configs:
- to: [email protected] <https://groups.google.com/>
send_resolved: true
- to: [email protected] <https://groups.google.com/>
send_resolved: true
