Lower Overhead than Java Profiling Tools
You no longer have to worry about impacting your end users because unlike many other Java profilers, in production environments, application overhead for running AppDynamics is less than 2%. Those organizations that use Java profiling tools only during urgent situations lack visibility into their app.
Automatic Application Discovery and Instrumentation
AppDynamics automatically maps and discovers the application tiers, like web services, databases and app servers,that the monitored JVM interacts with. In addition, AppDynamics allows you to locate your application bottleneck by letting you know where inactivity occurs in the application.
Business Transaction Monitoring
AppDynamics provides Business Transaction monitoring, which helps you to know your application similar to the way your end users experience it. Like AppDynamics, no other Java profiling tools provide Business Transaction information for bottlenecks.
With AppDynamics, you can set up alerts to find and fix problems before they even have a chance to affect your end users. Compared to AppDynamics, most other free Java profiling tools do not sound alerts, and those that offer alerts use static, universal thresholds often resulting in alert storms.
