Overview

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 you can sign that user off the application)

• Dynamically turn specific statistics gathering off and on

• Quickly navigate to any displayed information; for example, a specific user

• Obtain a range of information, including:

  • Node statistics counters and analysis

  • Behavior analysis figures (for example, the most-contended locks)

  • Lock conflict analysis

  • 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.

For details about running the JADE Web Application Monitor, see Chapter 2, "Monitoring Your Web Sessions", in the JADE Web Application Guide. For details about the Application Programming Interface (API) framework whose methods can be incorporated into JADE applications to examine a JADE system, nodes, or processes, see Chapter 4, "JADE System Instrumentation and Diagnosis", of the JADE Object Manager Guide.
