A Step-by-Step Guide to Java Garbage Collection Tuning

Working with Java applications has a lot of benefits. Especially when compared to languages like C/C++. In the majority of cases, you get interoperability between operating systems and various environments. You can move your applications from server to server, from operating system to operating system, without major effort or in rare cases with minor changes.

A Quick Start on Java Garbage Collection: What it is, and How it works

In this tutorial, we will talk about how different Java Garbage Collectors work and what you can expect from them. This will give us the necessary background to start tuning the garbage collection algorithm of your choice. Before going into Java Garbage Collection tuning we need to understand two things. First of all, how garbage collection works in theory and how it works in the system we are going to tune.

Understanding Java Garbage Collection Logging: What Are GC Logs and How To Analyze Them

When working with Java or any other JVM-based programming language we get certain functionalities for free. One of those functionalities is clearing the memory. If you’ve ever used languages like C/C++ you probably remember functions like malloc, calloc, realloc and free. We needed to take care of the assignment of each byte in memory and take care of releasing the assigned memory when it was no longer needed.

What Are Java Agents and How to Profile With Them

Java agents are a special type of class which, by using the Java Instrumentation API, can intercept applications running on the JVM, modifying their bytecode. Java agents aren’t a new piece of technology. On the contrary, they’ve existed since Java 5. But even after all of this time, many developers still have misconceptions about this feature—and others don’t even know about it. In this post, we remedy this situation by giving you a quick guide on Java agents.

Here's How to Calculate Elapsed Time in Java

Many things in programming sound like they should be easy, but are quite hard. Calculating elapsed time in Java is one of those. How hard could that be? As it turns out, it can be tricky. For starters, we have the fact that time itself is a tricky concept. For a quick example, remember that many places around the world observe Daylight Savings Time. Failing to take DST into account when you should, can and often does result in incorrect calculations.

Wavefront Introduces Java Tracing Agent Delivering Out-of-the-Box Application Observability

Distributed tracing is a critical piece of application observability. But instrumenting your applications with traces is not always easy. Whether you are an SRE or a developer, you need application observability. But you might not prefer to instrument code. That is where the Wavefront Tracing Agent for Java comes in handy, as it provides application observability without needing any code change.

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.

Gradle Build Files: Consistency Over Cute, Every Time

In the Java ecosystem, two build tools dominate the landscape: Maven and Gradle. Whereas Maven is XML oriented and therefore trades human readability for consistency, Gradle's DSL approach allows for more concise and human-readable build definitions. While there are certainly benefits to human readability, it also involves a risk which can, quite insidiously, invade your organization.
