The JADE Monitor provides systems analysis and diagnostic tools that enable you to:
Enable and disable the capture of data
Log captured data to file for subsequent replay in another JADE Monitor session
Extract class number cross-reference for subsequent replay in another JADE Monitor session
Capture ad hoc data to a Comma-Separated Values (CSV) file
Specify a periodic sampling interval
Specify which performance data items are to be periodically sampled
Perform ad hoc sampling of performance data items as a group
Sort displayed data
Print displayed data as it is currently displayed to the user
Load and replay historical data
Search for a specific user (for example, so that you can sign him or her off the application)
Dynamically turn specific statistics gathering off and on

Obtain a range of information, including:
Node statistics counters and analysis
Behavior analysis figures (for example, the most-contended locks)

Interactive method instrumentation
Information about the viewed data via an in-built knowledge base of information, or add your own information (for example, notes or tips) to the in-built knowledge base
This functionality enables you to monitor how well your system is running, to easily identify aspects that have the most impact on performance, and to quickly identify the likely cause of a problem in an emergency situation.
The diagnostic information is available in a number of levels of detail, ranging from a general overview down to detailed component analysis.
