The Java Virtual Machine (JVM) is the core of the Java application architecture. It interprets and translates the Java byte code into operations on the host platform. Because the Java middleware - including application servers such as Tomcat, JBoss EAP, WildFly, GlassFish, WebSphere, WebLogic - runs on the JVM, a performance issue in the JVM has a significant impact on business services it supports.
Monitoring of the JVM is an integral part of any Java application performance monitoring strategy. IT Ops and DevOps teams use JVM performance metrics to troubleshoot server-side bottlenecks. Developers and architects can also benefit from JVM monitoring by uncovering code-level issues.
eG Enterprise is a state-of-the-art Java performance monitoring solution that goes deep into analyzing issues across all Java tiers—from user experience, web front-end, application server, JVM, all the way to backend database and storage. Using JMX, eG Enterprise monitors JVMs in depth, tracking key performance indicators of all aspects of a JVM’s performance.
Unlike other JVM monitoring tools, from a single, easy-to-use web console, administrators and developers can analyze JVM performance, correlate it with other infrastructure metrics (server, virtualization, storage, etc.), and see actionable insights in the form of proactive alerts and intuitive dashboards for rapid problem diagnosis.
eG Enterprise analyzes hundreds of JVM performance metrics and identifies code-level bottlenecks including thread synchronization issues, deadlocks, memory leaks, GC issues and application configuration issues such as insufficient heap memory.
Since we don't control everything between our data center and client locations, events occasionally occur where service availability or application performance issues arise. eG Enterprise helps us pinpoint the nature and origin of the problem right away so we can resume normal operations as quickly as possible.
Java applications can fail or slow down if the memory available in the JVM is insufficient to handle the workload. eG Enterprise tracks usage levels of the JVM’s heap and non-heap memory and proactively alerts if memory usage levels are high.
Analysis of each of the memory pools including Eden space, Survivor space, Tenured gen and Perm gen space highlights how the JVM’s memory pool settings can be right-sized for improved performance. Memory monitoring at the JVM level also highlights any out-of-memory exceptions and potential memory leaks. In the latter case, top object types consuming memory are highlighted, making it easier for Java developers to fix memory leaks.
Most production Java applications are multi-threaded. eG Enterprise tracks all the thread activity in the JVM. With thread-level metrics, Java application administrators and developers can:
eG Enterprise allows you to easily track all garbage collection activity in the JVM: Identify when garbage collection happened, how often it is happening, how much memory is being collected each time and how long the garbage collection activity is running for.
Although the JVM performs automatic memory management, it cannot counter for memory leaks in your Java applications. Memory leaks are difficult to identify because they can take several days or weeks to manifest. Identifying the cause of Java memory leaks can be challenging, especially in production. eG Enterprise periodically takes and analyzes memory dumps of the JVM and identifies the top consumers of Java heap memory. Based on the automatic analysis of Java memory usage by eG Enterprise, administrators can be alerted to potential memory leaks in the application and can easily identify the exact Java class that may be resulting in a memory leak.
