JMX metrics give solid insights into the workings of your application. Integrating them with Levitate (our time series data warehosue) required us to jump some hoops with vmagent.

The core functionality of the Java Instrumentation API lies in its ability to modify the bytecode of classes being executed by the virtual machine. This capability allows for a range of monitoring tasks to be carried out, such as event recording and data gathering, which can provide valuable insights into an application's performance and behavior.

In this post, we’ll be delving into Java performance optimization, providing you with essential tips to write faster and more efficient code. If you’re reading this, you’re probably already aware of the importance of performance engineering and the need to optimize your code to ensure speed for all users, but even the most seasoned and performance-aware programmers can get tripped up.

Consider the scenario – You are an SRE (Site Reliability Engineer) joining a team to take charge of their Java applications. It has been reported that a Java application is very flaky in terms of memory issues.

Any software application or a system can have bugs and issues in testing or production environments. Therefore, logging is essential to help troubleshoot issues easily and introduce fixes on time. However, logging is useful only if it provides the required information from the log messages without adversely impacting the system’s performance. Traditionally, implementing logging that satisfies these criteria in Java applications was a tedious process.

Monitoring and troubleshooting distributed systems like those built with microservices is challenging. Traditional monitoring tools struggle with distributed systems as they were made for a single component. Distributed tracing solves this problem by tracking a transaction across components. In this article, we will implement distributed tracing for a Java Spring Boot application with three microservices.

Java is a class-based object-oriented programming (OOP) language built around the concept of objects. OOP concepts are intended to improve code readability and reusability by defining how to structure your Java program efficiently. There are seven core principles of object-oriented programming, as follows.

When you are building an application with Java (or any other language, for that matter), there are certain aspects that you need to monitor constantly. This monitoring helps a long way in retaining your product's marketability and improving customer satisfaction.
