Use the Minimum Required Response Time Dashboard Data Points to configure
the minimum amount of data Extreme Management Center requires before
displaying a given application or site pair. The data below this threshold is not
reliable and may set off a false alarm, however, you can adjust how much data is
required based on the individual needs of your network.
Each column in the dashboard represents an application. The top row displays
the average response time of all of the sites for that application, while the
following rows indicate the top worst performing sites for that application.
You can display or hide any of the application columns using the Views drop-
down list. You can also click the Xat the top of a column to hide the column
from the dashboard. Click the Single Row icon ( ) to display all columns in a
single row, or click the Double Row icon ( ) to display the columns in two
rows.
Click the Maximize icon ( ) to expand a single application column.
The worst performing sites are defined as those whose response time is the
slowest when compared to the expected response time observed over the
selected time period. For example, a site with an average Microsoft Office 365
authentication response time of 40 ms over the past seven days that displayed a
slowest response time of 50 ms would rank as a better performing site than a
site with an average Microsoft Office 365 authentication response time of 5 ms
over the same period that displayed a slowest response time of 30 ms.
