Top 7 Tomcat Metrics for Java Performance Monitoring

The Apache Tomcat software is an open-source implementation of the ava Servlet, JavaServer Pages (JSPs), Java Expression Language and Java WebSocket technologies. Tomcat is often used as a backend application server that connects to other web-facing servers like Apache and Microsoft IIS. Tomcat also includes its own native HTTP connector that allows it to be used as a standalone HTTP server.

JVM Tuning: How to Prepare Your Environment for Performance Tuning

When it comes to Java applications, to make sure they run at peak performance, it’s critical to close the resource gap between the code and the virtual machine it’s running on – if there is one. The way to do that is by peaking into and fine-tuning the Java Virtual Machine (JVM). However, that’s easier said than done. Many factors can influence JVM performance, and during tuning, you must consider all of them. Though, there are ways around that to make it not be such a pain.

Crafting the perfect Java Docker build flow

What is the bare minimum you need to build, test and run your Java application in Docker container? The recipe: Create a separate Docker image for each step and optimize the way you are running it. I started working with Java in 1998, and for a long time, it was my main programming language. It was a long love–hate relationship. During my work career, I wrote a lot of code in Java. Despite that fact, I don’t think Java is usually the right choice for microservices.

Monitor Java memory management with runtime metrics, APM, and logs

The Java Virtual Machine (JVM) dynamically manages memory for your applications, ensuring that you don’t need to manually allocate and release memory in your code. But anyone who’s ever encountered a java.lang.OutOfMemoryError exception knows that this process can be imperfect—your application could require more memory than the JVM is able to allocate.

Java Performance Tools: 9 Types of Tools You Need to Know!

Managing an application’s performance, and specifically keeping it in good condition, is one of the hardest challenges in software development. That’s true for virtually any programming language and platform. Java is no exception to this rule. But beyond that, Java also presents some unique challenges of its own.

How to Check Memory Usage in WebLogic Console and Monitoring WebLogic JVM Heap and CPU Usage in WLSDM

Weak JVM performance affects WebLogic domain performance directly. That’s why the host’s CPU and memory usage is very important in terms of improving WebLogic performance. Higher CPU consumption and Garbage Collection duration can cause applications to run slowly, even cause the WebLogic servers facing downtime. JVM instances in a WebLogic need to be monitored constantly and notification/alarm infrastructure must be installed as well.

11 Simple Java Performance Tuning Tips

It’s one thing to write code that works. But what about clean, readable, concise code? That’s another thing entirely. To create an app that solves one problem? Not that hard. What about one that not only solves the problem, but it’s also easy and pleasurable to use? Now we’re talking. You could apply the same reasoning for many software properties, which would make for a long article. Instead, let’s focus on only one of those properties: performance.
