 Kubeye aims to find various problems on Kubernetes, such as application misconfiguration, cluster components unhealthy and node problems(using [Node-Problem-Detector](https://github.com/kubernetes/node-problem-detector)). Besides predefined rules, it also supports custom defined rules.
 
+## Architecture
+Kubeye gets cluster diagnostic data by calling the Kubernetes API, by regular matching of key error messages in logs and by rule matching of container syntax. See Architecture for details.
