A persistent log of all faults and defects is available under Logs as the Fault log. For more information, see Fault Log Entries.
Faults and defects are subcategories of Alerts. Filter rules can be configured to cause the appliance to email administrators or perform other actions when faults are detected. For more information about alerts, see Configuring Alerts in Oracle ZFS Storage Appliance Administration Guide, Release OS8.7.x.
