Use the Set Aging window to set aging for the hosts in a selected Host group. Using the Aging feature populates the Expiration Date and the Inactivity Date fields on the Host Properties window. Hosts with existing age times are modified. This option is only valid for Host groups. If a host is a member of more than one group, the aging time is applied based on the last group to which the host was added or the last group whose aging times were modified.
Adding age times to existing hosts can cause some hosts to be removed from the database immediately depending on the creation date of the host record. If, for example, the creation date is 01/01/2010, today's date is 02/02/2010 and Days Valid is set to 5, then the Expiration Date calculated is 01/06/2010. The record is deleted immediately.
If hosts have been manually set to Never Expire, the Expiration Date and Inactivity Date fields for those hosts will not be modified by adding those hosts to a group with aging settings. See Properties, Set host expiration date and Aging out host or user records for additional information.
- Select System > Groups.
- Right-click on the host group and select Set Aging.
- Enter a number for Days Valid or Days Inactive. The number in days valid is used to calculate the expiration date for each host in the group. The number in days inactive is used to calculate the inactivity date for each host.
- Click OK.
