# Rationale
The alert handler serve as central component for building reactive self-healing systems, based on Prometheus.
It is meant to be a single binary, which will be distribued and installed to all nodes of clusters.
The routing itself is delegated to alertmanager of Prometheus.
It is main functionality is to `selfheal` and handle Prometheus alerts automatically, which are fired by Prometheus.
The alert-handler share a common declarative API with the alertmanager (based on labels) which need to be respected by users. See [API](doc/api.md)
