Java Monitoring: Top Tips and Best Tools to Know

By on December 9, 2020

Java programming language is easy to use and often employed by web developers to develop applications. However, monitoring a Java-based application’s performance might become challenging as it’s not a straightforward process. Troubleshooting inefficiencies requires implementing several monitoring techniques to track Java logs, metrics, infrastructure data, and other operational aspects. The following sections list some of the most widely used best practices that may guide you to monitor Java-based applications effectively, along with the list of top Java monitoring tools to help you excel at monitoring Java-based applications.

Top Java Monitoring Tips to Optimize Applications

Get Started With Code Profiling

Experts recommend users initiate monitoring of Java-based application with systematic code profiling. This is a direct approach to isolate inefficiencies and regressions in the code. Profiling the Java code helps you identify slow performing areas in the Java virtual machine (JVM) system. To overcome manual code profiling hassles, developers must download profiling software with live code profiling capabilities to promptly detect code errors and pay more attention to troubleshooting.

Spot Java Log Errors With Transaction Tracing

Transaction tracing helps track errors within the Java logs. It’s feasible to use transaction tracing software to trace app transactions. Efficient software helps identify slow transaction areas and quickly traces the transactions back to their origins in the log data. Tracing application transactions is an effective way to get to the root cause of errors in the Java logs.

Optimize Logging Libraries for Smart Troubleshooting

A strong understanding of JVM logging libraries simplifies the monitoring process and accelerates Java performance troubleshooting. Users with knowledge about logging libraries know how to effectively revisit log data for faster troubleshooting. Users can access Java logging libraries manually or via automated log management software to get details regarding SMTP server logs, console logs, and other historical Java logs for effective troubleshooting.

Find and Fix Performance Bottlenecks

It’s imperative to detect and resolve performance bottlenecks early in the process to avoid application slowdowns or malfunctions. You should analyze an array of JVM performance metrics such as garbage collection, heap usage, and response time to effectively identify and prioritize bottlenecks according to the issue severity. A JVM troubleshooting software automates bottleneck detection and helps to fasten the troubleshooting.

Track Exceptions to Increase Efficiency

In Java, the term “exception” has a unique connotation and is defined as a pre-configured code line that helps identify programming errors. Monitoring exceptions helps fine-tune Java performance. Leverage a JVM troubleshooting software to speed up exception tracking—it aids monitoring by providing corresponding exception metrics and graphical summaries.

Embracing the above listed Java monitoring best practices can help you notch up your Java application performance. Now, let’s look at some of the top Java monitoring tools available.

Best Tools for Powerful Java Monitoring

There are various Java monitoring tools available, so it’s critical for users to select the best-fit solutions for their requirements. Let’s deep dive into this list of widely used Java monitoring tools.

SolarWinds AppOptics

JProfiler enables users to overcome performance challenges while identifying memory leaks. It also helps users have a better understanding of threading issues. JProfiler helps developers view a set of objects from various angles with the help of a smart UI. This tool also allows developers to solve memory problems.

Eclipse Memory Analyzer (MAT)

Memory must be monitored continuously in a Java-based system. Java objects are stored in heaps, and when an application runs, the heap’s storage fluctuates in size. The Eclipse Memory Analyzer works as a Java heap analyzer and helps pinpoint the memory leaks. It also reduces memory consumption and analyzes productive heap dumps to calculate the retained sizes of objects. It also allows users to run a report for extracting leak suspects automatically.

Stagemonitor

Stagemonitor is built for monitoring applications in a distributed system. It’s useful for clustered application stacks and helps developers monitor Java-based applications running on multiple servers. Developers can use Stagemonitor to gain application performance insights in development, testing, and production stages. It provides an overview of real-time and historical data from both the cluster and the developer server and lets users create threshold-based custom alerts for better monitoring. JVM Dashboard from Stagemonitor allows users to access information about CPU and heap utilization, along with garbage collection behavior in real-time.

VisualVM
