IP Pool Utilization Thresholds
When IP address pools are configured on the system, they can be assigned to a group. All configured public IP address pools that were not assigned to a group are treated as belonging to the same group (automatically named "Public IP Pools"). Individually configured static or private pools are each treated as their own group.
IP address pool thresholds can be configured for all IP pools or pool groups configured within a system context or for individual pools or groups. These thresholds generate alerts or alarms based on calculations pertaining to percent-available for pool groups and percent-free, percent-on-hold, percent-released, and percent-used for individual pools.
Enter condition: When the actual IP address utilization percentage passes, or is equal to, the configured Threshold value an alert or alarm is set.
Clear condition: When the actual IP address utilization percentage passes the Threshold value the alert or alarm is cleared.
If a trigger condition occurs within the polling interval, the alert or alarm is not generated until the end of the polling interval.
The following table describes the possible methods for configuring IP pool utilization thresholds:
|Context-level||IP Pool Group: A single percent available threshold can be configured for all IP pool groups within a given context. The threshold is based on an aggregate measurement of available IP addresses for all IP pools within each group. NOTE: Separate alerts or alarms are generated for each group that experiences an event.|
|IP Pool: The following thresholds can be configured for all IP
address pools configured within a given system context:
|IP address pool-level||The following thresholds can be configured for each IP address
