Productivity Award: AppInternals Xpert

Two seconds, just two seconds. It doesn't sound like much — except to a company trying to serve Web pages to impatient customers. So what do you do if you aren't currently able to meet that high standard in your multitiered Web application?

AppInternals can come to the rescue. Its sole focus is helping you meet your performance requirements. It does this by putting minimal resource agents on every aspect of a multitiered system, whether portal servers or backend database. These agents collect detailed user, transaction, and internal performance metrics of classes, methods, and SQL statements including cross-server transaction analysis.

It then presents to stakeholders specific dashboards that give a quick surface summary of time-consuming trouble spots across one or many applications, along with hyperlinked drill-down data in separate presentations. I especially like the easy ability to navigate down to the lowest class, method, or SQL statement level and see its performance profile and activity numbers. Real-time transaction maps make it possible to identify the one or more things causing excessive delays, even if the transaction hops between servers. That discovery is tagged with a bookmark, a URL, which is mailable to other developers for additional analysis.

AppInternals' optimized database collects all the information from the agents. Thus, you can ask real-time Google-style questions like "Which test user accessed the homepage using the troublesome transaction identified in the drill down?" or "Which transactions use the troublesome SQL statement?" Predictably, other details, such as exceptions, can also be searched for. Whatever is happening inside your system, it's probable AppInternalsXpert will find it and reveal it to you in a display that contains a wealth of supporting data.
