Summary

In this chapter, we learned about the JFR profiler. With JFR, a high performance, low overhead profiler, built into the JVM, you won't need to rely on third-party profilers to troubleshoot your Java applications and HotSpot JVM.

We also covered MC—an advanced tool for developers and administrators to analyze the data collected by JFR in detail—visually, in local and remote environments.

In the next chapter, we'll cover multiple improvements and additions in JDK 11.
