Benefits of AppDynamics vs. free Java profilers:
Monitor the JVM's performance and availability
Notify health and performance issues of JVM
Troubleshoot and find root cause of performance issues of your application in minutes
Monitor MBean metrics in real-time
Lower Overhead than Java Profiling Tools
AppDynamics operates in production with an overhead of just 2% on the application. This means that even if it is left on all the time, it would not affect end users. Compared to AppDynamics, most Java profilers bring significant overhead and therefore they are used only during critical situations. As a result, most organizations that use Java profiling tools lack the insight into the application when it's performing normally.
Business Transaction Monitoring
No free Java profilers can identify and prioritize problems like AppDynamics. AppDynamics helps you to comprehend the application the way your end users experience it via Business Transactions. It categorizes user requests into Business Transactions and informs dev and ops teams about the performance issues that affect the end users the most.
Troubleshoot Java Code Latency in Minutes
With business requests and transactions being processed by the JVM, AppDynamics provides tremendous visibility into Java code execution. This helps you identify latency and find its root cause in minutes. This makes Java performance tuning much easier.
