How alerts work

Alerts notify administrators about important events that occur on the storage array. Alerts can be sent through email, SNMP traps, and syslog.

The alerts process works as follows:
  1. An administrator configures one or more of the following alerting methods in System Manager:
    • Email – Messages are sent to email addresses.
    • SNMP – SNMP traps are sent to an SNMP server.
    • Syslog – Messages are sent to a syslog server.
  2. When the storage array's event monitor detects an issue, it writes information about that issue to the event log (available from Support > Event Log). For example, issues can include such events as a battery failure, a component moving from Optimal to Offline, or redundancy errors in the controller.
  3. If the event monitor determines that the event is "alertable," it then sends a notification using the configured alerting methods (email, SNMP, and/or syslog). All Critical events are considered "alertable," along with some Warning and Informational events.

Alerts configuration

You can configure alerts from the Initial Setup wizard (for email alerts only) or from the Alerts page. To check the current configuration, go to Settings > Alerts.

The Alerts tile displays the alerts configuration, which can be one of the following:

  • Not configured.
  • Configured; at least one alerting method is set up. To determine which alerting methods are configured, point the cursor at the tile.

Alerts information

Alerts can include the following types of information:

  • Name of the storage array.
  • Event error type related to an event log entry.
  • Date and time when the event occurred.
  • Brief description of the event.
Note: Syslog alerts follow the RFC 3164 messaging standard.
