Build on the foundations of the fundamentals course, you’ll learn the advanced monitoring features coming with Icinga 2. Among high availability and cluster concepts you will gain insights into database, Java and VMWare monitoring. Integration with tools like Logstash and Graphite is another important part of the advanced training.
