backstage-plugin-opsgenie VS alertmanager

Last, but not least, Kévin Gomez from electric scooter sharing company VOI Technology contributed an Opsgenie plugin. It supports tabs for alerts and incidents and an overview widget to show the latest alerts for a particular service. #4227

- Alert Manager

You could use prometheus as a monitoring tool, blackbox_exporter to "export" the urls to prometheus, alertmanager for notifications, and grafana for nice gui dashboards (and maybe also notifications).

I found this other example below from this repo https://github.com/prometheus/alertmanager/issues/2559, but it is neither working.

vmalert: executes a list of the given alerting or recording rules against configured data sources. For sending alerting notifications vmalert relies on configured Alertmanager. Recording rules results are persisted via remote write protocol. vmalert is heavily inspired by Prometheus implementation and aims to be compatible with its syntax

Yes, I believe you can do all of what you're looking for without a UI. The alertmanager api has the ability to register receivers as well as to poll for alerts, silence them, etc: https://github.com/prometheus/alertmanager/blob/main/api/v2/openapi.yaml

I found it, unfortunately it doesn't help.

Prometheus recently added native support for time ranges in the alerting config https://github.com/prometheus/alertmanager/issues/876
