You have recently grouped multiple FortiGate devices into a single ADOM. System Settings > Storage Info shows the quota used. What does the disk…

The disk quota for an Administrative Domain (ADOM) on a FortiAnalyzer represents the total, shared amount of disk space allocated for storing logs from all devices managed within that specific ADOM. When multiple devices are grouped into an ADOM, their logs collectively consume space from this single, pre-configured quota. The System Settings > Storage Info pane displays this total allocated space for the ADOM and how much of it has been used by the combined logs of all its member devices.

A: The quota is a shared pool for the entire ADOM, not a separate limit applied to each individual device within the ADOM.

B: This describes the total physical or virtual disk capacity of the FortiAnalyzer appliance itself, from which individual ADOM quotas are carved out.

C: The quota is configured for a specific ADOM instance, not determined by a generic "ADOM type" (e.g., FortiGate ADOM).

"Configuring ADOMs" section: "You can configure the maximum disk space to be used by the devices in the ADOM. The disk quota is the amount of disk space that the ADOM can use." This confirms the quota is for the ADOM as a whole

encompassing all its devices.

"System Settings > All ADOMs" section: The table shows a "Disk Quota (MB)" column for each ADOM

reinforcing that the quota is an attribute of the ADOM itself.

config system adom command: The set disk-quota parameter is defined as "Disk quota for this ADOM in MBs (0 means no limit)." This shows the quota is a singular setting for the entire ADOM.
