Methods For Measuring Performance
There are two main methods by which application performance is assessed for production applications. The first is measuring the resources used by the application. The second is measuring the End User Experience which in and of itself has two components. The first, is the volume of transactions that are going through the system during the response time measurements, and the second is response time of an application from the perspective of the end user.
These methods for measuring performance will ultimately help build a performance baseline, which consists of three high level categories.
- Transaction Performance / Response Times (EUE). This can be measured at some point in the server, by a robot or simulated user, or by desktop agents that show the response time as measured at the desktop from the time the "enter" key is pushed to the time data is returned.
- Transaction Volume – (metrics trending)
- Resource Consumption (Infrastructure)
Application performance management is related to end-user experience management and real user management in that measuring the experience of real users in the use of an application in production is considered by many to be the most valid method of assessing the performance of an application. Maximum productivity can be achieved more efficiently through event correlation, system automation and predictive analysis which is now all part of APM.

Famous quotes containing the words methods, measuring and/or performance:
“A writer who writes, “I am alone” ... can be considered rather comical. It is comical for a man to recognize his solitude by addressing a reader and by using methods that prevent the individual from being alone. The word alone is just as general as the word bread. To pronounce it is to summon to oneself the presence of everything the word excludes.”
—Maurice Blanchot (b. 1907)
“By measuring individual human worth, the novelist reveals the full enormity of the State’s crime when it sets out to crush that individuality.”
—Ian McEwan (b. 1938)
“O world, world! thus is the poor agent despised. O traitors and bawds, how earnestly are you set a-work, and how ill requited! Why should our endeavour be so loved, and the performance so loathed?”
—William Shakespeare (1564–1616)
