Apache Tomcat, a widely-used application server for Java applications, is lauded for its simplicity and efficiency in handling smaller applications without the need for the full Java EE platform. This article explores how to utilize the ELK Stack and Logz.io for effective monitoring and analysis of Tomcat's access logs, which record critical data about client requests, including IP addresses and HTTP status codes. It provides detailed steps on installing Tomcat, configuring Filebeat and Logstash to ship these logs to Elasticsearch, and using Kibana for log analysis and visualization. The guide emphasizes the importance of combining access logs with other data sources, such as Catalina logs and JMX metrics, to gain a comprehensive understanding of Tomcat's performance. The process is designed to enhance troubleshooting and infrastructure optimization, with the visualization capabilities of Kibana offering an intuitive way to monitor traffic and server responses.
