The Monitoring portlet in Server portlets group allows you to monitor a local or a remote Geronimo server. The console is designed to monitor a Geronimo instance running in a separate JVM. The console can gather statistics and performance data from multiple Geronimo servers, and display this data graphically. The Monitoring console uses the Management EJB (MEJB) to gather statistics from a remote Geronimo server. You may also use JMX to gather statistics from a remote server, but this would require the remote server to install and run the org.apache.geronimo.plugins.monitoring/agent-car-jmx/2.1.4/car
plugin. The portlet screen is shown below:
The Monitoring console defines Servers and Graphs with statistics collected from servers, and Views consisting of one or more graphs. In this section, we will see how the Monitoring console plugin can be used to monitor a Geronimo server.
