Benefits: Accurately & quickly find root cause of complex incidents
AppDynamics helps to accurately identify and understand the root cause of complex incidents. For example, memory leaks are among the most difficult issues to detect and analyze. The AppDynamics tool identifies how long the problem existed, and performs drill-down in the Java application to reveal the underlying cause. Previously, the teams were circumventing these recurring incidents.
The APM tool has also shown excellent results in proactively addressing issues affecting application performance, for example, capacity planning. At certain times of the year, such as December and March, Bouygues Telecom experiences sales peaks. The AppDynamics tool helps detect when the system is close to saturation, in real time, then adjusts to accommodate peak loads.
“With AppDynamics, we have truly gained expertise, but we have become more proactive as well,” Holleville says. “We have moved from ‘black box’ status to ‘white box’ status. We know exactly which applications can create problems. With the AppDynamics solution, we are even able to calculate our partners’ response time, and contact them to improve the quality of our combined services.”
Currently there are about thirty people who use AppDynamics daily. A connector has been specially designed between the centralized monitoring system, Nagios, and AppDynamics, in order to benefit from an automatic increase of the alerts in Nagios (e.g. exceeding memory usage). Bouygues Telecom is the first company deploying this connector.
“AppDynamics is truly intuitive in its operation, and the self-learning system of the tool is very effective — it creates its own baselines based on past performance,” Holleville concludes.
