The Display Server is instrumented with JMX to allow you to manage and monitor the display cache and application settings. To enable JMX, you must run the Display Server using the -jmxport command line option:

    -jmxport:(port number)

The JMX Monitor demo, located in demos\jmxmonitor in your Enterprise RTView installation, shows how to use Enterprise RTView to monitor the Display Server using JMX. NOTE: Java 1.5.0_06+ is required.

The Display Server contains one MBean named RTViewDisplayServer:name=Manager with the following methods:
 

Method/Attribute	Type	Description
DisplayData	TabularData	One row for each cached display containing: Display Name - The name of the .rtv file for the display. Display Number - The display number. These values always range from 1 to N, where N is the number of displays currently in the cache. This number is not tied to a particular display (i.e. display name + substitutions), and can change as displays are automatically removed from the cache. Last Reference Time - The amount of time that has elapsed since the display was last requested by a client.  When this time exceeds the Display Timeout, the display is eligible for automatic removal from the cache. Substitutions - The substitution string for the display.
DisplayTimeout	int	The current display timeout setting.
ImageQuality	float	The current image quality setting.
MaximumDisplayCount	int	The current maximum display count setting.
NumberOfDisplays	int	The number of cached displays.

The RTViewDisplayServer:name=Manager MBean also supports the following commands:
 

Method/Attribute	Description
clearDisplayCache	Clears the cached displays as well as preloaded displays.
setDisplayTimeout	Set the display timeout.
setImageQuality	Set the image quality.
setMaximumDisplayCount	Set the maximum display count.
