Enterprise Java Applications are N Tiered and complex. The Java Virtual Machine (JVM) improves productivity of Java developers by hiding JVM memory handling details. However this throws new challenges in JVM monitoring in production as improper clean up of JVM memory can cause the application to slow down. Every application administrator hence needs to ensure optimal JVM configuration and monitor JVM Memory and monitor JVM performance.
A poorly tuned Java application can cause slow degration in JVM Performance, which in turn can cause the application to become slow for end users. JVM Garbage collection is the mechanism by which the VM (Virtual Machine) frees up memory for Java Applications.
ManageEngine® Applications Manager helps monitor a Java Virtual Machine's garbage collection time, heap memory, threads and other key metrics to ensure the JVM has good performance.
You can configure thresholds on various attributes. The fault management capability helps to generate alarms and notifications to enable you to take corrective actions. The ability to even execute JMX MBean Operations helps take corrective actions automatically in a production setup.
ManageEngine Applications Manager can help monitor JVM Memory : Heap and Non Heap Memory. Additionally you can monitor how the Virtual Machine allocates the objects in memory for various memory spaces like Eden Space, Survivor space, Tenured Generation etc. Each memory location has its own importance and by monitoring these in production, along with tweaking configuration parameters on JVM startup, a Java application can be tuned well.
The JVM stats help understand how classes are loaded and unloaded from the JVM. It also gives metrics about how much time is spent by the JVM in garbage collection and helps understand throughput.
To start monitoring your JVM or Java Applications, download ManageEngine Applications Manager now or learn more about Java Runtime Monitoring.
