Jetty web server metrics

Beginning with OneAgent v1.77, Dynatrace reports new metrics for Java processes that contain a Jetty web server. These metrics are available on each Java process page.

As you can see below, the process infographic contains a new tab called Jetty metrics. If you have a Jetty web server, then the number of Jetty requests is also displayed in the infographic.

Similar to Apache and IIS monitoring, Dynatrace reports the load and traffic associated with each process. However, this is just the beginning; click Further details to get even more insights. This view currently shows the Jetty thread pool and more details about Jetty traffic, like the number of open connections.

Note: Dynatrace attempts to activate JMX monitoring metrics—however Jetty doesn’t always include JMX monitoring metrics. If you don’t see Jetty metrics the reason may be that the respective classes aren’t in the classpath. To get the metrics, restart Jetty using the following option:
--module=jmx

Those who know me know that I'm passionate about 3 things: rock climbing, physics, and performance. I've worked in performance monitoring and optimizations in enterprise environments for the better part of the last 10 years. Now as a Product Manager I am doing my best to build those experiences into Dynatrace.
