Just in time for the upcoming Webinar with The BonTon Stores, where we talk
about the challenges in operating complex WebSphere environments, we had
another set of prospects running their applications on WebSphere. Francis
Cordon, a colleague of mine, shares some of the screenshots resulting from
these engagements.
In this article I want to highlight important areas when managing performance
in WebSphere environments. This includes WebSphere Health Monitoring,
End-to-End Performance Analysis, Performance and Business Impact Analysis as
well as WebSphere Memory Analysis and Management. More details will be
discussed during the Webinar on May 25th – so check it out if you are
interested.
WebSphere Health Monitoring
WebSphere Application Servers provide many different metrics that we need to
consider when monitoring server health. This includes system metrics such as ... (more)
In the last week my task was to create stable functional tests for a new
eCommerce application. We picked several use cases, e.g.: clicking through
the different links, logging in, searching for products and actually buying a
product. We needed functional tests that run on both Internet Explorer and
Firefox. With these tests we want to make sure to automatically find any
functional problems but also performance and architectural problems (e.g: too
many JavaScript files on the site, too many exceptions on the server or too
many database statements executed for a certain test scena... (more)
When we get engaged with prospects that are interested in our performance
management solution we walk them through a Proof of Concept. We let them
install dynaTrace on their own prior to the actual POC. During the POC we ask
them to exercise typical use cases on their application that show performance
problems. We walk them through the different analysis options and add the
findings to a final POC Presentation. In this blog I want to share some
screenshots and findings of a typical Proof of Concept recently done in a
heterogeneous .NET/Java Environment.

With its latest release, dynaTrace updates its Product Suite for Deep Dive,
Automated Cross-Browser Web Performance Optimization with two products:
dynaTrace AJAX Edition 3.0 is the free standalone tool that has been
downloaded by 30k+ users so far supporting both Firefox (3.6, 4.0) and
Internet Explorer (6, 7 & 8) dynaTrace Development Team Edition is the
Premium Upgrade and provides extended automation, end-to-end performance and
automated regression analysis for modern Web 2.0 Applications
In this first part of the series I focus on the capabilities that support web
developers ... (more)
I am currently working on a blog where I am going to explain how to do
cross-browser testing and performance analysis using dynaTrace. Before I am
going to blog that How-To I want to share with you one thing that I have
noticed when executing my tests in Internet Explorer 8 and Firefox 3.6. Test
execution times are very different – but – this is not because one
browser is slower than the other. It is because Selenium has different
synchronization mechanisms in IE and FF to e.g: wait for a page to be loaded.

I run a simple test on the latest 2.0 Beta build of Seleniu... (more)
