The Subnet monitoring events section of the Event hooks data grid lists the current default values. To change the default values, select Set defaults and make the desired changes in the dialog.
Note: The global subnet monitoring setting can be overridden for individual subnets by
changing the setting explicitly for the subnet. For information on how to change
monitoring settings for individual subnets, refer to Setting subnet monitoring.
To change the default values:
- In the Subnet monitoring events section of the Event hooks data grid, select Set defaults.
- In the dialog, edit the default values as needed:
- Enabled: When selected, all subnets are monitored by default. If you only want to monitor a subset of the subnets in the system, clear the checkbox and enable monitoring for the individual subnets instead by setting subnet monitoring on the IPAM page.
- Script to invoke: Select the script to run when the number of free addresses goes below the set threshold.
- Add ScriptRunner authentication parameters: Select this option to use ScriptRunner to give the script temporary access to the API. For more information, refer to Using the ScriptRunner.
- Email address: Enter the email address that should be the recipient of notifications when the number of free addresses goes below the set threshold.
- Dynamic threshold: Enter the threshold for the free addresses in a
DHCP scope address pool.Note: For split scopes and scopes in a superscope (on MS DHCP servers), and address pools using the shared-network feature on ISC DHCP servers, the total number of free addresses in all scope instances is used to calculate the number of free addresses.
- Static threshold: Enter the threshold for the free addresses in a subnet.
- Only perform action once (until resolved): When selected, the action is performed only once when the number of free addresses goes below the threshold.
- Perform action when resolved: When selected, the action is performed when the number of free addresses is no longer below the threshold.
- Select Save.
