Managing event messages

The Event Management System (EMS) collects and displays information about events that occur on your storage system. You can manage the event destination, event route, mail history records, and SNMP trap history records. You can also configure event notification and logging.

Event messages for high-severity events appear on your system console or LCD, if your system has one, and are written to the system's event log. An event message consists of the following elements:

• Message name
• Severity level

  Possible values include the following, listed in decreasing order of urgency:

  • EMERGENCY (the system is unusable)
  • ALERT (action must be taken immediately to prevent system failure)
  • CRITICAL
  • ERROR
  • WARNING
  • NOTICE (a normal but significant condition has occurred)
  • INFORMATIONAL
  • DEBUG
• Description
• Corrective action, if applicable

You can manage the following event capabilities:

• Event destination

  Specifies the destination to which events are sent. Destinations can be email addresses, SNMP trap hosts, or syslog servers.

• Event route

  Specifies which events generate notifications. An event route is a mapping between events and their destinations. An event route includes information about severity, destinations, and notification thresholds.

• Event notification and logging

  Specifies the email "from" address, the email "to" address, whether to send events to the console, and the maximum size of the log file.

• Mail history records

  A list of emailed event notifications.

• SNMP trap history records

  A list of event notifications that have been sent to SNMP traps. For information about SNMP traps, see the Clustered Data ONTAP Network Management Guide.
