Prometheus Alert Manager (https://prometheus.io/docs/alerting/latest/alertmanager/) is able to monitor Kubernetes and send Alerts. It should be very useful to do a plugin which can report alerts from Alert Manager defined by rules. There are some API's available.

Alerts
https://prometheus.io/docs/alerting/latest/alertmanager/
This should allow to query Alerts

Rules
https://prometheus.io/docs/prometheus/latest/querying/api/#rules
This should allow to query the defined rules and the active alerts for the rules. Maybe we can do all with this endpoint

It should be nice to have filter for rules, this would allow to have a dedicated service for any rule. Rule Discovery should be nice
