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 perform Java performance monitoring.
JVM Garbage collection is the mechanism by which the VM(Virtual Machine) frees up memory for Java Applications. ManageEngine® Applications Manager's JVM monitor helps keep an eye on 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 of our Java VM monitoring tool extends to generation of alarms and notifications and also enables you to take corrective actions-even execute JMX MBean Operations automatically in a production setup.
ManageEngine Applications Manager's Java memory monitoring tool give you extensive information about 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 given by Applications Manager's JVM monitoring tool helps 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.
It allows us to track crucial metrics such as response times, resource utilization, error rates, and transaction performance. The real-time monitoring alerts promptly notify us of any issues or anomalies, enabling us to take immediate action.
