Today, almost any metric you can think of can be tracked down and reported, as opposed to the past when the software was traditionally provided in boxes and its performance in production could not be predicted. The issues we are currently facing are not due to a lack of information, but rather to an abundance and scale of information. This becomes significantly more difficult to manage when dozens or even hundreds of servers are in use.

We are constantly working on contributing monitoring support for various sources, the latest in that line is support for Tomcat monitoring using the JMX Receiver in the OpenTelemetry collector. If you are as excited as we are, take a look at the details of this support in OpenTelemetry’s repo. You can utilize this receiver in conjunction with any OTel collector: including the OpenTelemetry Collector and observIQ’s distribution of the collector.

Write enough programs, and you’ll agree that it’s impossible to write an exception-free program, at least in the first go. Java debugging is a major part of the coding process, and knowing how to debug your code efficiently can make or break your day. And in Java applications, understanding and leveraging stack traces can be the game-changer you need to ship your application quickly. This article will cover how to debug in Java and how Java stack traces simplify it.

The Java Management Extensions (JMX) framework is a well-known tool for any experienced Java developer. The purpose of the JMX framework is to simplify the management of local and remote Java applications while providing a user-friendly interface. The primary advantages of the JMX framework are that it’s highly reliable, scalable, and easy to configure. However, it’s also known for introducing the concept of MBeans, which unlocks the capacity for real-time Java application management.

For developers who’ve created their own instrumentation with the Java Agent plugin, the next phase of the process is regression testing. By performing regression testing, you can ensure that your plugin functions the way it’s supposed to after you’ve made code changes or updates. You’ll have your own plugin, but to illustrate regression testing in this article, I’ll use the plugin in our example repo.

Java has been one of the most widely used programming languages among developers worldwide for years. So naturally, it is a popular choice for those beginning their careers in development. Learning Java requires more than just knowing the proper syntax and effective code hygiene. Any developer who hopes to use Java for commercial development must be able to quickly and competently identify and recognize errors in their code.

Garbage collection in Java is a familiar term in the coding world. You will come across it when learning the Java programming language. Because it’s built into Java memory management, the garbage collector is one of Java’s crucial features. It helps prevent serious errors and allows programmers to create new objects without worrying about unwanted objects.

Let’s look at IllegalArgumentException, which is one of the most common types of exceptions that Java developers deal with. We’ll see when and why IllegalArgumentException usually occurs, whether it’s a checked or unchecked exception, as well as how to catch and when to throw it. We’ll use a few examples based on common Java library methods to describe some of the ways to handle IllegalArgumentException.
