Logs

Alerts

This is the appliance alert log, recording key events of interest during appliance operation.

The following are example alert log entries as they would appear in the BUI:

Table 3-6  Example BUI Alert Log Entry Displays

Time Event ID Description Type 2013-9-16 13:01:56 f18bbad1-8084-4cab-c950-82ef5b8228ea An I/O path from slot 'PCIe 0' to chassis 'JBOD #1' has been removed. Major alert 2013-9-16 13:01:51 8fb8688c-08f2-c994-a6a5-ac6e755e53bb A disk has been inserted into slot 'HDD 4' of chassis 'JBOD #1'.

An information icon next to the Event ID means that extended information is available. Click the icon to display information below the list of alerts.

The appliance can also be configured to send email, raise an SNMP trap, or perform other actions when particular alerts occur. This is configured in the Alerts section. All alerts appear in this log, regardless of whether they have actions configured for them. For more information about alerts, see Chapter 9, Alert Configuration, in Oracle ZFS Storage Appliance Administration Guide .

Faults

The fault log records hardware and software faults. This is a useful reference when troubleshooting hardware failure, as timestamps are available for these hardware fault events.

The following are example fault log entries as they would appear in the BUI:

Table 3-7  Example BUI Fault Log Entry Displays

Date Event ID Description Type 2013-9-5 17:42:35 9e46fc0b-b1a4-4e69-f10f-e7dbe80794fe The device 'HDD 6' has failed or could not be opened. Major Fault 2013-9-3 19:20:15 d37cb5cd-88a8-6408-e82d-c05576c52279 External sensors indicate that a fan is no longer operating correctly. Minor Fault 2013-8-21 16:40:48 c91c7b32-83ce-6da8-e51e-a553964bbdbc The ZFS pool has experienced currently unrecoverable I/O failures. Major Error

These faults generate alert log entries that use the alert reporting settings (such as sending email), if configured. Faults that require administrator attention appear in Problems. For more information, see Problems.

System

This is the operating system log, available to read via the appliance interfaces. This may be useful when troubleshooting complex issues, but should only be checked after first examining the alert and fault logs.

The following are example system log entries as they would appear in the BUI:

Audit

The audit log records user activity events, including login and logout to the BUI and CLI, and administrative actions. If session annotations are used (see Chapter 7, User Configuration, in Oracle ZFS Storage Appliance Administration Guide ), each audit entry should be noted with a reason.

The following are example audit log entries as they would appear in the BUI:

Phone Home

If Phone Home is used, this log shows communication events with Oracle support. For information about Phone Home, see Phone Home Service in Oracle ZFS Storage Appliance Administration Guide .

The following is an example phone home entry as it would appear in the BUI:
