Differences between alarms and user alerts

Configured event notifications provided by alarms are not the same as the automatic user-alert threshold messages sent to users.

You can configure alarms to notify specific recipients when specific events occur or when events of a specific severity type occur.

In contrast, alerts are notifications sent automatically to users who exceed space quotas. Whenever a user event related to disk or file quotas occurs, DataFabric Manager sends an alert to the user who caused the event. The alert is in the form of an email message that includes information about the file system (volume or qtree) on which the user exceeded the threshold for a quota. You can disable the alerts either for all users or for the users who have quotas.

The following list summarizes the differences between alarms and user alerts.

Configuring
Alarms: You must configure alarms before notification is sent to the specified recipients.

User alerts: User alerts are sent by default.

Recipients
Alarms: Alarms can be sent to one or more of the following recipients:
  • An email address
  • A pager email address
  • An SNMP trap host
  • A script that you write

User alerts: User alerts are sent to the user who exceeds the user quota thresholds. User alerts can be only in the form of an e-mail message.

Trigger
Alarms: You can configure alarms for any event, any event class, or any severity level.
User alerts: User alerts can be sent only when the following user quota events occur:
  • User Disk Space Quota Almost Full
  • User Disk Space Quota Full
  • User Files Quota Almost Full
  • User Files Quota Full
