Monitor Tomcat metrics with Datadog

Apache Tomcat is an open-source HTTP web server that supports Java technologies and is commonly used to serve Java applications. It consists of Catalina, Coyote, Jasper, and Cluster components. Monitoring Tomcat's performance metrics is crucial for maintaining a positive end-user experience. Datadog integrates with Apache Tomcat to collect metrics and provide visualizations and alerts based on real-time performance data. Key metrics include general Tomcat metrics (e.g., error count, request count), thread pool metrics, and Catalina servlet metrics (e.g., processing time). By monitoring these metrics, users can identify potential issues affecting their web applications' performance.
