Apache Tomcat Monitoring

Features for Apache Tomcat

Germain provides monitoring capabilities for Apache Tomcat, allowing you to track the uptime, performance, and user experience of your Tomcat applications. Germain monitors Tomcat from various standpoints and leverages multiple data sources, such as logs, portal, and JavaScript injection, to gather insights into its performance and user experience.

Here are some key aspects of Germain's monitoring capabilities for Apache Tomcat:

Uptime Monitoring

Germain continuously monitors the availability and uptime of your Apache Tomcat server. It ensures that the server is up and running, responding to requests, and serving your applications without any disruptions.

Performance Monitoring

Germain tracks the performance metrics of your Apache Tomcat applications. It captures data related to response times, throughput, resource utilization (CPU, memory), and other performance indicators. This information helps you identify performance bottlenecks, optimize resource allocation, and ensure smooth application operation.

Response Time

Track the response time of the Tomcat server to ensure it is within acceptable limits. Monitoring response time helps identify performance issues and potential bottlenecks.

Request Rate

Monitor the rate at which requests are being received by the Tomcat server. Tracking the request rate helps identify sudden spikes in traffic or unexpected changes in usage patterns.

Thread Pool Usage

Monitor the usage of the Tomcat thread pool, including the number of active threads and the size of the thread pool. Monitoring thread pool usage helps identify thread contention issues or thread pool exhaustion.

Memory Usage

Monitor the memory usage of the Tomcat server, including heap and non-heap memory. High memory usage can lead to performance degradation and potential out-of-memory errors.

Garbage Collection

Monitor the frequency and duration of garbage collection cycles. Analyzing garbage collection logs helps optimize memory management and identify potential memory leaks.

Error Logs

Regularly check the Tomcat server's error logs for any reported errors, warnings, or exceptions. Analyzing the error logs can help identify potential issues, misconfigurations, or application errors.

Connection Pool Usage

If your Tomcat server uses connection pooling (e.g., with a database), monitor the usage of the connection pool. This includes tracking the number of active connections, connection timeouts, and connection errors.

Servlet/JSP Execution Time

Monitor the execution time of Servlets and JSP pages to identify any performance bottlenecks or slow-running components.

Log File Monitoring

Monitor Tomcat's log files, including access logs and application logs, for relevant information, such as HTTP status codes, error messages, or custom log entries.
