With a Java-Datalogger we can write events and alerts to different data sinks. For example we can use ElasticSearch and Kibana to discover alerts collected by WinCC OA. Elasticsearch provides full text search, analytics, dashboards. And now it also supports graphs!
“Graph introduces a new way to discover, and explore, the relationships that live in your data. Adding relevance to the process of exploration, a unique combination of graph and search means you can do things like detect fraud, recommend content, and more.” https://www.elastic.co/de/products/graph
