Profilers bundled in the JDK

The JDK includes profiling tools that can provide us with valuable insights into our Java application’s performance. The use of these tools is highly recommended to identify performance issues and opportunities for performance fine-tuning. This section explores the primary profilers that are built-in to the JDK – JVisualVM and Java Mission Control (JMC).

JVisualVM

The JVisualVM, short for Java Visual Virtual Machine, is a robust profiling tool built into the JDK. It offers an impressive set of features that include monitoring, profiling, and troubleshooting Java applications.

An overview and features

JVisualVM provides a graphical user interface that combines several JDK tools, including JConsole. The interface is displayed in the following figure.
