Why would alertname need to be present? I can be relabeled away by Prometheus alert_relabel_config ..

The canonical way to solve this is to use the external labels in Prometheus.

I think the original request is valid and should be done like we do prometheus query logging.

This is logging *notifications*, not *alerts*. Webhook can not tell you if other webhooks calls succeeds.

Let's change from ``` global: template_config: delim_left: "[[" delim_right: "]]" ``` to ``` template_config: delim_left: "[[" delim_right: "]]" ``` I am concerned because this will break all built-in templates.

This should be settable in the webhook receiver, that's what I am talking about

mmh indeed we would need to first update the alertmanager, it's not supported yet. So you could try setting the env variable in the alertmanager: `PROMETHEUS_COMMON_DISABLE_HTTP2=x`

I think this might be on purpose and written for simplicity. Alertmanager has at least once promise, it's better to send one extra alert than miss one.
