In the last two ducklings, I finished the extensive discussion on breakpoints and switched my focus to the watch area. In it, we have several amazing and lesser known tools that let us build insight into our running application. These tools include a filter filter, stream debugger and a tool to mute renderers. JetBrains introduced the tool as a plugin and currently as a built-in tool in the Java 8 tool.

There are four basic types of breakpoints: line breakpoints, method breakpoints and conditional breakpoints. The exception breakpoint is a remarkably useful feature that everyone knows about, but everyone shuns and hates it. Code that stops on an exception thrown and caught inside the JVM is redundant.

KoolKits (Kubernetes toolkits) are highly-opinionated, language-specific, batteries-included debug container images for Kubernetes. In practice, they’re what you would’ve installed on your production pods if you were stuck during a tough debug session in an unfamiliar shell. To briefly give some background, note that these container images are intended for use with the new kubectl debug feature, which spins up Ephemeral containers for interactive troubleshooting.
