Oracle^® ZFS Storage Appliance Analytics Guide, Release OS8.8.0

Using Advanced Analytics Statistics

These statistics are only visible if Advanced Analytics is enabled in Preferences (see Setting Appliance Preferences in Oracle ZFS Storage Appliance Administration Guide, Release OS8.8.0). These are statistics of lesser interest and are not typically needed for system observability. They are often dynamic which can induce higher overhead, and expose more complex areas of the system which require additional expertise to understand properly.
