STAS fault tolerance
You can configure multiple domain controllers as STAS collectors and add them to a collector group in the firewall for fault tolerance.
The collector priority is in the order shown in the collector group. The first collector in the group is the primary collector, and the succeeding collectors are backups. If the primary collector goes down, the firewall gathers the data from the backup collectors. You must create a collector group for each domain or sub-domain. You can add a maximum of five collectors to a collector group.
Example
The primary collector for testlab.com (collector group 1) is 192.168.1.10, while 192.168.1.185 is the backup. The sub-domain remote.testlab.com is in collector group 2 and has 192.168.2.20 as a standalone collector.
