TODAY'S TOP SOA & WEBSERVICES LINKS Product Review
AmberPoint Express from AmberPoint, Inc.
Something to keep on hand
By: Brian Barbash
Digg This!
Not surprisingly, Web services management tools are quickly appearing to assist developers and system administrators alike with the maintenance of service-based applications. One such product is AmberPoint Express, a free Web services management and monitoring tool whose mission is to provide developers with the ability to "...incrementally measure, debug and fine-tune the performance and functionality of their Web services..." The product is currently available in three flavors: .NET, WebSphere, and Apache Tomcat with Axis. Versions tailored to other major application servers will be released in the future. AmberPoint Express is targeted to developers and provides the functionality for monitoring and debugging Web services. However, all of AmberPoint's products are based on a distributed architecture geared to managing and monitoring Web services applications. The key components of their architecture are:
When AmberPoint Express is installed, instrumentation agents that monitor traffic against the deployed services are plugged into the application server. For the .NET release, agents are installed directly into IIS, while the Tomcat version is shipped with a preconfigured release of Tomcat 4.0.6 (Express may also be installed on an existing instance of Tomcat). An additional feature of the .NET release is direct integration within Microsoft's Visual Studio .NET IDE, providing access to the debugging functionality. Using AmberPoint Express The lower section of the information area shows summary statistics for the currently selected Web service within the context of the overall time interval. Figure 1 is an example of the five-minute time interval. Summary information is presented for the entire five minutes, including the number of successful messages, the number of faults, average response time, the average number of successful messages transferred, and the maximum number of messages transferred. Additionally, summary information is presented for the five-second time slice locked on the graph. A time slice may be locked by clicking the mouse within the graph at any data point. If viewing the graph using the one-hour interval, the same information is presented; however, each individual time slice is one minute in duration. Data from this view may also be exported to Microsoft Excel for further analysis. By clicking the Export Data link, an Excel spreadsheet is generated on demand and downloaded in a separate browser window. The data exported includes the start and end times of each time slice in the graph, the number of messages and faults processed, and the average and maximum response times for the operation or service. Debugging Tools Developers may also send test messages to any monitored Web service using the AmberPoint Express GUI. By selecting an individual operation on a service and invoking the Send Message operation, a new message is created and presented to the developer. At this point, the data to be sent may be edited, along with the number of messages to send and the address to send the message to. For example, if a production message fails, the console can be used to create a test message from the production service, which can in turn be directed at a test server, eliminating the risk of modifying production data. Working in Visual Studio In addition to the managed property, a new item is placed in the Tools menu of Visual Studio, providing quick access to the View Messages and Send Test Message areas of the AmberPoint console. These items are available for any item in a project that is being managed by AmberPoint. Company Info Download Information Summary

Many organizations make
the faulty assumption
that SOA is a panacea
that can, and should be,
applied to every
situation. The reality is
that service orientation
is not the right answer
for every scenario. The
expense of service
orientation cannot always
be recouped and, in some

Open source has made

Adopting SOA is a lot
like gardening. It takes
time, skill, a lot of
hard work, and the
process can be messy and
even a bit frustrating at
times. I know you've
probably heard tons of

Thus far in the SOA era,
there has been a heavy
