This old cat, Apache Tomcat, has been around for ages, but it’s still very much alive! It’s at version 9, with version 7.x still being maintained, while the new development is happening on version 10.0. We’ve just added support for Tomcat monitoring to the growing list of integrations the other day, so if you run Tomcat and need monitoring dashboards and alerting on various Tomcat’s metrics, give Sematext’s Tomcat monitoring a go!
Before you jump to the screenshot below, read this: you may reeeeeally want to enable Transaction Tracing in the Sematext monitoring agent running on your Tomcat boxes. Why? Because that will help you find bottlenecks in your web application by tracing transactions (think HTTP requests + method call + network calls + DB calls + ….). It will also build a whole map of all your applications talking to each other with information about latency, request rate, error and exception rate between all component! Check this out (and just click it to enlarge):
Everyone loves maps. It’s human. How about charts? Some of us have a thing for charts. Here are some charts with various Tomcat metrics, courtesy of Sematext Monitoring:
