Analyzing end-user experience with the User tier
The User tier in the Application View provides a visual indication about the page performance, in the selected five-minute period, compared to the set Minor and Critical thresholds. The User tier reflects the experience from the end user's point of view. An end user is considered active if the user interacts with a page, or if an open page invokes an AJAX request (even without user interaction).
This topic describes how to use the User tier to identify performance and availability problems in your application.
Before you begin
To see the Application View tab, your system must include TrueSight App Visibility Manager, including the App Visibility proxy component.
You must have
Application Operator
-level access, or higher.
Determine if end users are experiencing problems with the application
In the Application View, the User tier displays the number of user that are experiencing one or more problems (latency violations or errors) with pages, page operations, or application issues during the selected period. The tier displays the number of users that are adversely impacted by latency violations or errors:
- Impacted Users (number inside the circle). Number of active end users in the selected five-minute period that are experiencing latency issues or errors that exceed the defined thresholds.
- Colored part of the circle. Ratio of impacted users to total number of users. The color reflects whether the percentage of users experiencing issues exceeds the defined thresholds.
- Total. Total number of active application users in the selected five-minute period
App Visibility Manager adds the BMCTSEUM cookie to the browsers of end users and reads the cookies to monitor user experience.
The following example describes the information in the User tier:
Example of the User tier
For the five-minute period reflected in the example, the User tier shows that the number of active end users experiencing latency issues or errors is 217 out of a total number of 1,863 active users. The colored part of the circles shows that approximately 10% of all the users are impacted at the time.
