In this section we introduce how to work with Kieker. Starting with methods to obtain Kieker, configure and apply Kieker, and writing your own probes and event types. We use the small sample application Bookstore to illustrate how to work with Kieker. However, there exists a wide variety how to apply Kieker to applications and services. We will only cover manual and basic AspectJ instrumentation to discuss basic concept. There is more documentation available (how-to-apply-insturmentation) which illustrates different techniques to instrument depending on the technology.
