Quickly get to the root-cause of Java application problems and discover if it's the code, database queries, JVMs, or the underlying infrastructure that's causing slow application response to users.Start Your Trial
Many server-side applications are written in Java and process tens of millions of requests per day. Key applications in various domains like finance, healthcare, insurance and education are Java-based. When these applications slow down, they affect the user experience and in turn, reduce business revenue.
IT operations, application operations and DevOps teams often spend days troubleshooting Java application performance issues. Since Java applications are multi-threaded and involve multi-tier architectures, it is a challenge to identify whether the problem is due to the client, the network, in the JVM, in the application code, with the SQL query, or in the underlying infrastructure. Monitoring of the Java application stack end-to-end is necessary to ensure peak application performance and user satisfaction.
eG Enterprise provides a powerful and easy-to-use set of Java performance monitoring tools that address the key needs of IT operations, Application operations and DevOps teams.
eG Enterprise is an end-to-end APM solution for Java applications. With its integrated application and infrastructure monitoring capabilities, you can:
With eG Enterprise, we can now quickly identify root causes of incidents, resolving them before users are impacted. Automatic prioritization and categorization of alerts helps us better focus on the important issues and prioritize our resources accordingly.
Using an advanced tag-and-follow approach, eG Enterprise traces every business transaction (from web browsers and native mobile apps) that flows through the Java web and middleware tiers and allows quick identification of the cause of transaction slowness.
Monitor all aspects of the health and performance of Java web containers hosting the applications and the underlying Java Virtual Machines (JVMs).
Application performance is often affected by anomalies in the underlying IT infrastructure, including the server operating system, hardware, hypervisor, network, and storage devices. In such cases, monitoring tools that only look at the application layers will not be helpful.
Using a converged approach to application and infrastructure monitoring, eG Enterprise allows IT administrators to monitor, analyze and correlate application performance with infrastructure performance. From a unified web console, administrators can see the performance every layer and every tier. A patented auto-correlation engine analyzes performance insights, presents a visual topology map of the infrastructure including interdependencies across the various tiers, and pinpoints the root cause in seconds.
Key metrics of a Java application’s performance include availability (i.e., is it responding to user requests), latency/response time to requests (i.e., how quickly do users receive responses) and throughput (i.e., how many requests are serviced in a given period of time).
Java performance monitoring refers to the monitoring of all the layers of a Java application in order to determine how well it is performing and where bottlenecks might be. Java performance monitoring includes monitoring of the Java virtual machine, the web application server (if applicable), and application transactions. By unearthing bottleneck, Java performance monitoring allows developers and application operations teams to fine-tune the code and the application configuration to deliver better performance.
No, Java performance monitoring applies to any Java application – whether it is web-based or standalone. Specific aspects of monitoring may apply only to web applications – e.g., a standalone Java application may not use a web application server like Oracle WebLogic, Apache Tomcat, JBoss, etc.
No, Java performance monitoring does not require any changes to the application code. JVM metrics (garbage collection, threads, classes, memory leaks, etc.) are collected using Java Management Instrumentation (JMX) APIs. Application server monitoring is performed using APIs supported by the application server. Application transaction tracing is done using byte-code instrumentation which is performed in a manner transparent to the application code, yet allows monitoring tools to track every database query, every Java method call, and so on.
The best Java application monitoring tool depends on your requirements. There are dozens of monitoring tools available, from free tools that monitor specific processes, to comprehensive end-to-end application performance monitoring tools like eG Enterprise. If performance, uptime and digital experience are important to you, then you should consider eG Enterprise for your Java performance monitoring.
Monitoring your Java CPU usage can be done with simple free tools like JConsole. However, monitoring resource usage like CPU and memory is monitoring the symptom of an underlying cause. To truly understand your Java application performance you should use a complete Java application performance monitoring tool that can analyze your application code to help identify processes that are causing CPU and memory spikes.
Monitoring your Java memory usage can be done with simple free tools like JConsole. Many free tools provide inputs to the administrator and require 24x7 oversight to detect problems. Typically for production environments, you need enterprise-class monitoring tools like eG Enterprise that can track the health of 100s of Java applications simultaneously, can provide proactive alerting and do not need constant manual supervision.
Yes, Java application performance monitoring can highlight threads (and code) that are taking excessive CPU, indicate if the JVM is not sized correctly (e.g., Java memory heap is too small), point out database queries that are not optimal, indicate Java methods that are taking more time, etc. By acting on these inputs, you can tune your Java application and improve its performance.
