• The condition.
Each rule specifies a single condition. A condition includes a time base and a threshold. Refer
to
“MAPS conditions” on page 1802 for additional information.
• The actions to take if the condition is evaluated to be true.
Refer to “MAPS actions” on page 1803 for additional information.
The combination of actions, conditions, and measures allow you to create a rule for almost any
scenario required for your environment.
MAPS conditions
A condition includes a time base and a threshold. If the condition is evaluated as true, the rule is
triggered. The condition depends on the element that is to be monitored.
Consider the following rule:
For all F_Ports, if the change in the CRC counter in the last minute is greater than 10, then
fence the port and issue a RASLog message.
In this rule, the condition is whether the change in the CRC counter in the last minute is greater
than 10.
Thresholds
Thresholds are the values at which potential problems might occur. For example, in configuring a
port threshold, you can select a specific value at which an action is triggered because of too many
threshold violations.
Time base
Time bases specify the time interval between two samples to be compared. You can set the time
base to Day (samples are compared once a day), Hour (samples are compared once an hour), or
Minute (samples are compared every minute).
The time base affects the comparison of sensor-based data with user-defined threshold values.
For measures where the time base is not applicable, the time base is automatically set to None.
