Benefits of AppDynamics over free Java profilers
Easily monitor the performance and availability of your JVM
Alert JVM health and performance issues
Find and fine tune SQL and NoSQL latency
Get to root cause of application performance issues quickly
Monitor MBean metrics in real-time
Automatic Application Discovery and Instrumentation
AppDynamics, like Java profiling tools, automatically identify and map the application tiers that the tracked JVM interacts with (other application servers, web services and databases). A large number of free Java profilers do not have a graphical user interface revealing the application topology and response time breakdown, making it more difficult to easily identify the problems areas.
Lower Overhead than Java Profiling Tools
AppDynamics runs in production with an overhead that's less than 2 percent. It can be left on all the time without the worry about an impact on end users.
Business Transaction Monitoring
With AppDynamics, you can understand your application through Business Transactions, just as your end users experience it. Most of the Java profiling tools are unable to provide Business Transaction context for bottlenecks, making difficult to identify and prioritize problems quickly and easily.
AppDynamics allows create alerts on Business Transaction, application, and JVM metrics. This way, you can detect and fix issues before end user performance is impacted. While most of the free Java profilers do not offer alerting, the Java profiling tools using static, universal thresholds usually result in alert storms.
