Troubleshooting Spring Applications with Epsagon

Spring is an application development framework for Java. But as any developer will tell you, Spring and Spring Boot are more than just frameworks. They have become synonyms for Java because most web-based applications written in Java are based on the Spring framework. This is due to the fact that when it was first introduced in 2003 by Rod Johnson, it brought a much-needed structure to Java projects and made it very easy for anybody to get started with building small and large applications in Java.

DevOps Checklist for Distributed Tracing

So what is Distributed Tracing anyway? In the olden days, to debug problems, developers would typically log into the server running the software and inspect the logs and maybe some real-time metrics to investigate the issue.
