Under what situation must ADOMS be enabled on FortiAnalyzer?

ADOMS, or Administrative Domains, must be enabled on FortiAnalyzer specifically when a FortiMail device wants to register with it. This is because FortiMail requires ADOMs to effectively manage its log data and reporting functionalities. In this context, ADOMs allow for separate management of log data from different devices, such as FortiMail, ensuring that the logs are organized and can be easily accessed and analyzed without interference from other data.

FortiMail generates unique logs and reports that benefit from being isolated within its own ADOM, especially in environments where multiple types of devices are being monitored simultaneously. This separation is crucial to maintain clarity and performance, particularly when handling varying types of traffic and security events.

While FortiGate devices do indeed register with FortiAnalyzer, they typically do not require ADOMS for registration or logging purposes, as their logging can be managed directly. Similarly, ADOMS are not primarily intended for system performance enhancements, nor are they required for connecting to FortiManager. Therefore, the necessity for enabling ADOMS is specific to scenarios involving FortiMail registrations with FortiAnalyzer.
