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.
The Network Service Dashboard displays the performance (in response time) of
your network services. Each column in the dashboard represents a service:
l ALL
l DHCP
l DNS
l Kerberos
l LDAP
l RADIUS
The top graphs for each service displays the average response time of all of the
sites for that service, while the following rows indicate the top worst performing
sites for that service.
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.
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 RADIUS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 RADIUSauthentication response time of 5 ms over the same period that
displayed a slowest response time of 30 ms.
Expected Response Time
The Expected Response Time bar graph displays the range of response times,
the most recently measured response time, and the expected response time for a
network service a specific site during the date range you configure in the Date
Range drop-down list. The value displayed on the far right of the graph is the
