Description

The JMX Sensor is used to gather several information provided by the Java Management Extenstion (JMX). This information is represented by objects called MBeans (for Managed Bean) which can contain any kind of information (e.g.: system-load, up-time, thread-count, classes loaded, server-version, ...).

Configuration

For a detailed instruction about the configuration of the JMX sensor see <TODO>.

The User Interface

For the basic usage of the user interface see UI Basics.

If a JMX sensor was properly configured an item named JMX Data containing a bean icon Image Added will be shown in the data explorer view (see Data Explorer View for more information). This item contains two further items called Show all and Browser. By double-clicking the Show all item an overview of all monitored MBean attributes will be opened. A structured tree-representation of the monitored attributes is located under the data explorer view item Browser by which particular attributes can be accessed directly.

The center view contains an overview of all monitored MBean attributes and associated information. It is important to note that only the latest value of each MBean is shown. This is also the case if a time range was defined, then, the latest value in this time range will be shown.

MBean attribute values can be charted if its value is a numerical value or a Boolean expression (true, false, yes, no). A attribute can be charted if the respective row of the Charting column contains the chart icon Image Added.

To chart an MBean attribute, open the context menu on the desired entry and click on Display in Chart located in the Navigate To menu. See Charting of the JMX Data for detailed information about charting.
