IBM Monitoring and Diagnostic Tools - Health Center Additional Information

1.0 Tool Description

The IBM® Monitoring and Diagnostic Tools - Health Center is a low-processor and memory usage diagnostic tool for monitoring the status of a running applications on a number of differnt runtimes. The Health Center can also open some log and trace files for analysis.

The tool is provided in two parts; a native agent which collects data from a running application and an Eclipse-based client which connects to the agent, interpreting the data and providing recommendations to improve the performance of the monitored application.

When the client starts up, you will initially see a connection wizard. Either make a connection to a runtime containing an agent or cancel the wizard to open log files from disk using the file menu.

The client is split into subsystems, each representing a component of the runtime. The following subsystems are available:

Classes - information about classes being loaded
Environment - details of the configuration and system of the monitored application
Garbage collection - information about the heap and pause times
Locking - information about contention on inflated locks
Profiling - sampling profile of methods including call paths
I/O - information about file open/close activity
Native Memory - Native memory use
Threads - information about running threads
Method Trace - accurate timing analysis of running methods
WebSphere© Real Time - data specific to Real Time Java

Not all data is availabe for every runtime. See the help documentation include with Health Center for futher details.

Subsystems are represented as Eclipse perspectives. At startup, the Health Center shows the Status perspective, listing the subsystems and their overall status. When you have made a connection to a live source or opened a file, subsystems with data available will become links and any recommendations will be displayed. Switch to the subsystem perspectives using the links or the toolbar icons. You can return to the Status perspective using the furthest left toolbar icon.

The Health Center updates the displayed data and recommendations every ten seconds.

You can send bug reports, feature requests, and feedback through your IBM representative, or you can post feedback or ask questions on the Health Center forum.

2.0 Feature Updates

The following sections document updates to each revision of this feature

Support for monitoring WebSphere© Real Time for Linux virtual machines

Ability to make a new connection without restarting the Health Center client

View of connection details and status

Ability to change graph units (to date or clock time, for example)

Improved recommendations in the case of connection problems

Renamed menu options: 'Export data' is now 'Save data'

Minor defects corrected

IBM Monitoring and Diagnostic Tools - Health Center V1.1 allows monitoring of WebSphere Real Time for Linux. The monitoring of production environments that utilise WebSphere Real Time for Linux is not advised at this time. Limitations in trace output functionality require IBM Monitoring and Diagnostic Tools - Health Center to generate a log file which could consume unlimited amounts of disk space.
