Libertyproxybeat

Welcome to Libertyproxybeat - beat that utilises IBMJMXConnectorREST to retrieve JMX metrics for a Websphere Liberty Profile Instance.

This is still development version and I expect changes based on feedback.

This beat retrieves JMX metrics from a running Liberty Profile instance and sends them to Logstash or Elasticsearch. JMX metrics are requested via 'JMX Proxy Servlet' configured and enabled in Tomcat for HTTP listener. JMX Proxy Servlet is a lightweight proxy to get and set the Tomcat internals.

Liberty Profile configuration

In order to enable the JMX url required by this beat the following features need to be added

        <feature>restConnector-1.0</feature>
        <feature>monitor-1.0</feature>

You must also setup a user with with the tag

Example of request for HeapMemoryUsage

http://127.0.0.1:8443/IBMJMXConnectorREST/mbeans/WebSphere%3Atype%3DJvmStats/attributes?attribute=UsedMemory
