Chapter 12: Notifications

Notifications are Nasuni Management Console messages. You might receive the following types of notifications:

Admin: The system administrator has performed an action.
Info: The system has performed an action, or has changed its state, in such a way that the user might be interested, but that does not require action or attention.
Warning: Something unusual has happened, but the user need not take action.
Error: Something unusual or incorrect has occurred, and the user should take notice and try to resolve the situation, if possible. Errors generate email messages to the user, if the user has set up email. See “Email Settings” on page 436 for details.
Alert: Something unusual or incorrect has occurred, and the user should take notice and try to resolve the situation, if possible, or contact Nasuni for assistance, if necessary. Alerts generate emails to the user, if the user has set up email. For details, see “Email Settings” on page 436. Examples of alert notifications are:
- Software update available.
  Warning: Do not attempt to restore from a virtual machine snapshot or backup.
- Account issues.
- Local cache issues.
- Evaluation period expired.

Retaining Notifications

Notifications are retained according to the following rules:

Review of notifications occurs daily on the NMC and weekly on the Nasuni Edge Appliance.
The most recent 50,000 Info-level notifications per Nasuni Edge Appliance are retained. However, Info-level notifications are removed after 7 days.
Acknowledged notifications of any level are removed after 14 days.
The most recent 750,000 unacknowledged notifications per NMC are retained. For this reason, it is important to acknowledge Alert, Warning. and Error level notifications regularly, so that they can be removed.
