I don't like having alerts sent by e-mail. Since I don't get e-mail notifications on my watch, I often do not see alerts for quite some time. They are also much harder to read in an e-mail client (Fastmail web an K-9 Mail both display them poorly). I would much rather have them delivered via _ntfy_, just like all the rest of the ephemeral notifications I receive. Fortunately, it is easy enough to integrate Alertmanager and _ntfy_ using the webhook notifier in Alertmanager. Since _ntfy_ does not natively support the Alertmanager webhook API, though, a bridge is necessary to translate from one data format to the other. There are a few options for this bridge, but I chose [alexbakker/alertmanager-ntfy][0] because it looked the most complete while also having the simplest configuration format. Sadly, it does not expose any Prometheus metrics itself, and since it's deployed in the _victoria-metrics_ namespace, it needs to be explicitly excluded from the VMAgent scrape configuration.
