Configuring Alarms
Managing Virtual Alarms
3 In the Status logic section, select one of the following three options:
Virtual alarm status is best status among selected alarms (AND) — Choose this
option to have the contribution of the sub-alarms calculated using the optimistic
version of the alarm logic tables.
Virtual alarm status is worst status among selected alarms (OR) — Choose this option
to have the contribution of the sub-alarms calculated using the pessimistic version of
the alarm logic tables. This is the most common option, since it brings changes in the
status of any sub-alarms to the attention of the operators.
Virtual alarm status is critical if selected alarms differ (XOR) — Choose this option to
have the contribution of the sub-alarms calculated using the XOR version of the alarm
logic tables. This causes the virtual alarm to reflect whether or not all of its sub-alarms
have the same status. If all sub-alarms are the same, the virtual alarm will be green.
Otherwise, it will be red.
For a more detailed description of the difference between these options, refer to
“Understanding the Alarm Logic Tables” in the iControl User Guide.
4 In the Text logic section, determine what to include in this virtual alarm’s text attribute
by selecting one of the following three options:
Ignore texts — No text logic (default).
Concatenate texts — Concatenate the text attributes from all sub-alarms.
List errors — List the text attributes from the sub-alarms that are in error.
5 Select the alarm provider you wish to use from the list in the left-hand part of the GSM
alarm browser pane.
6 In the right-hand part of the alarm browser, select the alarms that are to be sub-alarms
of the new virtual alarm, and then click the large down arrow button to transfer them
to the table in the bottom half of the window.
