Dynatrace is an APM solution that provides deep visibility into application performance across complex, distributed environments. It uses PurePath technology to capture timing and code-level context for all transactions end-to-end. This allows Dynatrace to identify performance issues and their root causes faster than other tools. Dynatrace can monitor Apache Tomcat servers and provide metrics on JVM performance, database queries, requests, and more. It helps diagnose common issues like inefficient database access, microservice problems, and coding issues.
