The WebSphere Liberty JMX server monitoring extension in Dynatrace provides information about requests and their state, JVM metrics and thread pool insights (better monitored with the companion Connection Pools: WebSphere Liberty extension).
This is a JMX (Java Management Extension) Dynatrace extension. JMX is ideal for monitoring applications built using Java. Make sure you are monitoring your WebSphere Liberty process as the extension does not support gathering metrics from the client-side.
Click on Add to environment to get started.
Prerequisites
- Windows or Linux
- OneAgent version 1.275+
- Dynatrace version 1.275+
- Java Metric Extensions 2.0 (JMX) [Opt-In] OneAgent feature enabled.
Output
The dashboard WebSphere Liberty JMX Overview will be included in the extension, where you can see an overview of your WebSphere Liberty JMX metrics.
Additionally, all metrics captured by the extension will be appended to the process group instance's unified analysis screen in three new sections: JVM, Servlet and Thread pools. Make sure to be on the new screen for process group instances to see them.
All metrics can also be viewed with the data explorer.
Licensing Consumption
The extension consumes DDUs. However, the free tier included with every host applies. You can further control this consumption by turning metrics on and off via the use of feature sets.
The amount of DDUs consumed depends on the number of instances monitored.
