Understanding Condition Groups
A condition group is a set of user-defined rules governing alert triggers and resets.
By default, the condition group Trigger Alert when all of the following apply is
added when new alert triggers or reset conditions are created. Four different logical
descriptors are used to create conditions: all, any, none, and not all, and clicking the
word all and enables you to select different values. The following sections describe
these logical descriptors.
All Condition Group
Trigger Alert when all of the following apply means that every condition in the
group must be true before the alert is triggered.
In the following example, there are three conditions within the condition group:
n Node Status is equal to Up
n Percent Loss is greater than or equal to 75
n CPU Load is greater than or equal to 85
This alert will not trigger unless the Node is Up, packet loss is greater than or equal
to 75%, and CPU load is greater than or equal to 85%.
When setting the condition group to all, picture every condition as being separated
by an and statement. So, in this example, the alert trigger would read:
Alert when: (Node Status = Up) and (Percent Loss >= 75) and (CPU Load >= 85)
