Top Stories by Alois Reitbauer

2010 is over and there has been a lot going on in the application performance space.  We started this project at the beginning of the year inspired by Stoyan Stefanov’s   performance advent calendar of 2009. (There is also one for 2010). Now twelve months later we have our 2010 performance almanac available. According to Wikipedia an almanac is -”… an annual publication containing information in a particular field”. Our performance almanac contains nearly 50 articles of numerous topics around application performance. We hope that there are topics for everybody. The articles range from technical to conceptual areas of performance management.  They reflect what took our attention throughout the year. We hope that you enjoy reading them. Week 1 – The Proactivity of Troubleshooting This article takes a deeper look into the nature of troubleshooting  of performance pro... (more)

Do You Need to Monitor Your Mobile Apps?

The increasing adoption of mobile applications as part of a company's online services leads to the question of whether we need to monitor it like other parts of our IT infrastructure. As they are part of our shipped application services we need to ensure they are working properly. However, not every application must be monitored the same way. In addition, monitoring always comes at a certain cost. We need people to take care of the monitoring, we have to prepare our applications to be ready for monitoring and we potentially also have to buy or at least integrate new monitoring to... (more)

A Step-by-Step Guide to dynaTrace AJAX Edition

  The dynaTrace AJAX Edition has been out there as an Alpha for a couple of weeks. It gave you the first impression what was to come. All the feedback we have received (like that from Steve Souders, and all that has come in via the contact form and the online forum) in that time made it possible to improve the tool from its early versions to its first "official" release version. In this article I'll discuss why dynaTrace Labs built the AJAX Edition, which problems it solves and how to use it in an example with Google maps. Why dynaTrace AJAX dition - and why for free? At dynaTrace... (more)

Applying Maslow’s Pyramid to Application Performance

This time I take an a bit of an unconventional approach towards defining performance management. The idea for this article came through a number of customer engagements, where the same question came up over and over again: “How do we start with Application Performance Management and what should we do?” Over time I developed a simple model which I called the performance management pyramid. The basic idea is to assign performance management activities to several levels. Each level serves a specific need and builds on top of the lower ones. Just like a building it starts with the b...

Challenges in Tracing JavaScript Performance by Example

In an earlier article I already discussed several approaches towards end-user experience (or performance) monitoring including their pros and cons. In this article I will present a simple real world sample which shows the limits of performance traceability in AJAX applications. As I don’t like Hello World samples, I thought I’d rather build something a bit more useful. The sample uses the Twitter API to search for keywords. The search itself is triggered by typing into a textbox. While the sample isn’t spectacular from a technical perspective, I will make it more interesting by ... (more)
