Alerts
When measuring a system under test with the Control Center, you may
notify a person in case of a specific problem. Therefore you select the menu
option
Filters|Alerts
. As shown in Figure 5.5, you will in a first step define a
condition for the alert. This is done in the "Limit Definition" section. In a
second step you will define what action should be executed if the condition
defined is fulfilled during the measurement. Check the button titled "Execute
program on alert", and enter a program that is to be executed. This may be a
batch file, or , as shown in the example setup in Figure 5.5, the Windows
network command "net send" to send a message via an IP network.

Clearing the Result File

measurements, select the menu
View|Clear...
and confirm the warning
which pops up with a click on yes. If you want to archive the results you
should copy the result file to a safe location before. The default location for
the result file is
c:\programme\opera\databases\results.txt
. As mentioned
in Section 5.1, you may choose a different location on your computer where
you want to store the result file.

The Averages Functionality
As a default, the Averages functionality is switched on in the Control Center.
If this option is activated, the results are divided into groups. The groups are
defined according to the very first column in the result view. Within these
groups, all result values are averaged and the average values are shown in
yellow-colored lines above every group.
If you prefer a simpler view of the results, switch off the average of the result
values. Just use the menu "View"|"Show Averages" to toggle between the
two modes.
