When ADOMs are enabled, each ADOM has its own reports, libraries, and advanced settings. Make sure you are in the correct ADOM before selecting a report. See Switching between ADOMs.
Some reports are available only when ADOMs are enabled. For example, ADOMs must be enabled to access FortiCarrier, FortiCache, FortiClient, FortiDDoS, FortiMail, FortiSandbox, and FortiWeb reports. You can configure and generate reports for these devices within their respective default ADOM. These devices also have device-specific charts and datasets.
