Apple has announced that with iOS8, which was made available to the public on September 17, Apple no longer stores the encryption key of the device so that the device can be unlocked by law enforcement. This encryption architecture is important for the corporate reader to understand, to help protect corporate assets. So I thoughtRead More
Measure the Real End-User Experience
SharePath Real User Monitoring (RUM) Express provides a real-time view into the actual experience of your end-user, including availability, response times, and service levels. This free, enterprise-class software helps isolate problems and pinpoint bottlenecks in your data center, network, or online application.
Monitor all transactions 24×7 for visibility into the true end-user experience and know whether any applications require immediate attention.
85% Lower Cost
Supports multiple applications for approximately 85% less than other comparable real user monitoring solutions.
This post is not a usual one since I simply want to address a technical question: “what is Java bytecode instrumentation (BCI)” and also explain what can and can’t be done with BCI regarding the problem of transaction tracing. It’s just that I’ve been asked about it again and again, and there is a real confusionRead More
Here we explain how SharePath Transaction Topology Mapping works and how it lets users pinpoint performance problems in an application and automatically map components in an architecture through auto discovery. What is transaction topology mapping? A topology is a directional graph that shows how objects are related to each other. In terms of performance monitoring, aRead More
In the perfectly elastic, brand new, and unfortunately mythical enterprise that we mentioned earlier, all applications were developed using Java, .Net, PHP, Ruby, or another modern environment. It is certainly true that there are many Enterprise Application Performance and Real User Monitoring tools that work well for new or existing applications written on one ofRead More
How do you escape from good Enough island? Most people start with a fresh look at their strategy, architecture, and software portfolio. They do a white board exercise and design a cloud-centered, standards-based, open source, SaaS, PaaS, IaaS, NaaS, …everything-as-a-service environment. That’s the fun part. Then they map the “as is” to the “toRead More
Remember three-second response times? In the days when everyone wore a suit to work, application performance was measured in seconds. Any response time less than three seconds was a victory. At ﬁve seconds, the telephone calls began. More than that and there was bound to be a meeting. As an experiment, Google application performance. You will get more thanRead More
Do you experience application hang problems? If so, read this article to discover the top 3 reasons applications hang and cause slow performance. If you have been in the IT industry long enough, you probably know this story well. The application works fine, then, suddenly, the application hangs with no apparent reason. You restart theRead More
In order to have a better understanding about performance and real user monitoring, one should have some understanding of statistics. (This is increasingly true as that is the technology that drives analytics.) The most basic statistics are the average, standard deviation, and the variance. Here we explain those in the simplest possible manner (so thoseRead More
One of my favorite domains to review in existing applications, because it tends to be so error-ridden, is … error-handling. Too many programmers regard a language’s exception-handling syntax as a solution rather than just a mechanism, so error-handling tends to be misguided or at least neglected. A little more attention in this area often paysRead More
Is it OK to use WebSockets? Absolutely. Why, then, reader Klaas Hemstra wonders, did I write in “The Dangers of HTML5: WebSockets and Stable Standards” that the WebSocket protocol is an “unstable spec”? The short answer is that this was the best I know in March 2011 when I wrote these words; the preceding hyperlinkRead More
