Application Performance Monitoring |
||
How well are your applications serving your users?You can monitor application response time, round-trip network delay, server responsiveness, database transactions per second, and myriad other low-level statistics. But what’s the bottom line? Are your end users satisfied or frustrated? How can tell, systematically, before you hear from them on the phone?
Introducing Apdex, the Apdex Performance Index from the Apdex Alliance, an industry consortium.Think of Apdex as an Application Satisfaction Index. Apdex is a built-in feature of the WildPackets OmniPeek Product Family. Through the WildPackets OmniPeek network analyzer, you can see an Apdex score, then drill down to the packets resulting in the score, along with Expert Analysis and graphical tools such as Packet Visualizer. Apdex measurements are performed at the task level. A task is a meaningful unit that an end user performs in the context of an application. For example, loading a Web page or submitting a database transaction could be considered a task. Apdex is essentially a statistical measurement, so several samples of satisfied, tolerating, and frustrated are required for accurate interpretation of the Apdex index. The recommended minimum count per the Apdex specification is a generous 100 samples. Fewer samples than this are acceptable, provided that the total sample count used to derive the index is available. In OmniPeek, as few as 10 samples are sufficient to produce an Apdex rating.
The OmniPeek analyzer reports Apdex scores for the application running on your network.Learn more about Apdex today. |
