ADF Performance Monitor: Monitoring with Percentiles

What is best metric in performance monitoring – averages or percentiles?┬áStatistically speaking there are many methods to determine just how good of an overall experience your application is providing. Averages are used widely. They are easy to understand and calculate – however they can be misleading.

ADF Performance Monitor – Major New Version 7.0

We are very happy to announce that a major new version 7.0 of the ADF Performance Monitor will be available from May 2018. There are many improvements and major new features. This blog describes one of the new features; on usage statistics and performance metrics of end-user click actions.

A click action is the start trigger event of an HTTP request by the browser, by an action that a user takes within the UI. These are most often physical clicks of end-users on UI elements such as buttons, links, icons, charts, and tabs. But it can also be scrolling and selection events on tables, rendering of charts, polling events, auto-submits of input fields and much more. With monitoring by click action you get insight in the click actions that have the worst performance, that cause most errors, that are used most frequently, e.g. You can see in which layer (database, webservice, application server, network, browser) the total execution time has been spent. You can SLA monitor the business functions that are behind the click actions – from the perspective of the end-user. (Lees meer..)
