 Sowohl End-2-End-Testing als auch End-2-End-Monitoring folgen dem gleichen Paradigma – sie betrachten eine Applikation aus der Sicht des End-Users. Hier darf es keine Rolle spielen, in welcher Oberflächentechnologie die Applikation geschrieben ist oder in welcher Art sie mit dem End-User in Verbindung tritt. Genau an diesem Punkt setzt das Open-Source-Tool Sakuli an.

 There are a lot of articles that show how to monitor an [OpenShift](https://www.openshift.com/) cluster (including the monitoring of Nodes and the underlying hardware) with [Prometheus](https://prometheus.io/) running in the same OpenShift cluster. This article however is based on a different scenario: You are responsible for an application on an [OpenShift](https://www.openshift.org/) cluster and want to monitor just this application, but you don't have any administrative permission on it. The reason for this can be that you are working in a big company where the operation of the OpenShift environment is outsourced or the process to introduce a new monitoring solution takes way too long or the current monitoring solution doesn't match your requirements and so on.

 Database communication is an essential part of many applications, when persistent data storage is required. May it be orders, customer data, product recommendations or product information, if persistent storage is in place, the data contains a certain business value. Therefore it's important that your software handles your persistent storage the right way.
