Application Performance Management - Methods For Measuring Performance

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:

    Generalization, especially risky generalization, is one of the chief methods by which knowledge proceeds... Safe generalizations are usually rather boring. Delete that “usually rather.” Safe generalizations are quite boring.
    Joseph Epstein (b. 1937)

    We recognize caste in dogs because we rank ourselves by the familiar dog system, a ladderlike social arrangement wherein one individual outranks all others, the next outranks all but the first, and so on down the hierarchy. But the cat system is more like a wheel, with a high-ranking cat at the hub and the others arranged around the rim, all reluctantly acknowledging the superiority of the despot but not necessarily measuring themselves against one another.
    —Elizabeth Marshall Thomas. “Strong and Sensitive Cats,” Atlantic Monthly (July 1994)

    Nobody can misunderstand a boy like his own mother.... Mothers at present can bring children into the world, but this performance is apt to mark the end of their capacities. They can’t even attend to the elementary animal requirements of their offspring. It is quite surprising how many children survive in spite of their mothers.
    Norman Douglas (1868–1952)
