kuberhealthy

An operator for synthetic monitoring on Kubernetes. Write your own tests in your own container and Kuberhealthy will manage everything else. Automatically creates and sends metrics to Prometheus and InfluxDB. Included simple JSON status page. Supplements other solutions like Prometheus very nicely!
