“When they saw that, the programmers went ‘Bingo!' and we were able to fix it.” The page that took minutes to load was displayed within seconds. “Without AppDynamics, I doubt whether even now we would have found the issue.”
George's favorite feature of the AppDynamics APM solution is its built-in alerts. “I set up exception monitoring, and the tool immediately alerts me if there is a problem,” he said. “Out-of-Memory exceptions usually happen when a new user tries to do something with the wrong search parameters. With millions of patient records in the database, a string of bad searches like this can essentially cause serious issues.” With alerts in place, George was able to identify potential performance problems before they occurred.
Washington University also liked the ability to provide fine-details related to the execution of a single business transaction. This allowed George to quickly triage a performance problem down to the class and method level. “Without the AppDynamics platform, it's hard to see even what the method does, unless you're a programmer. But with AppDynamics, we can find out which method is taking the most time and drill down into the details. It's really helpful in finding issues.”
