What is JVM profiling?
JVM profiling refers to the processes of monitoring and analyzing Java virtual machine (JVM) parameters and performance metrics including object creation, thread execution, method execution, heap memory, and garbage collection. Profiling is typically carried out to track and analyze memory and CPU usage for performance tuning purposes.
JVM profiling tools help you collect the metrics necessary for implementing Java troubleshooting and for improving the overall efficiency and performance of your Java application delivery environment. Using JVM profiling tools, you can find memory leaks, resolve garbage collection delays, detect deadlocks, identify synchronization issues, and investigate other memory- or performance-related problems. With the right tool, you can better understand the health and behavior of your Java application delivery environment and diagnose performance issues quicker.
Tools used for JVM profiling
There are a variety of tools that can be used to implement JVM profiling and carry out Java application troubleshooting. One type of tool commonly used for JMX monitoring and JVM profiling is built-in monitoring and management utilities. Custom in-house tools and third-party Java profilers are also used by many teams as part of their Java monitoring toolkit.
Although these types of profilers are helpful for memory leak detection and CPU usage tracking, they're best suited for development environments because of the negative impact they can have on application performance. Moreover, the profiling data supplied by these tools can be difficult to interpret, and most are not equipped with an alerting mechanism to notify you when performance or resource consumption thresholds are breached.
In production environments, an application performance monitoring (APM) tool will be a better option for JVM profiling. If Java monitoring is supported by the tool, an APM solution can be run in staging and production environments—with minimal overhead—and offer you the metrics and method-level visibility you need to optimize the performance and resource usage of your JVM and Java applications.
