You can add alerts based on a resource, such as a cluster, node, aggregate, or volume, and events of a particular severity type. As a best practice, you can add an alert for any of your critical objects after you have added the cluster to which the object belongs.
You can use the following guidelines and considerations to create alerts to manage your systems effectively:
You should provide a description for the alert so that it helps you track your alerts effectively.
You should decide which physical or logical resource requires an alert. You can include and exclude resources, as required. For example, if you want to closely monitor your aggregates by configuring an alert, you must select the required aggregates from the list of resources.
You should decide if an event of a specified severity type (Critical, Error, Warning) should trigger the alert and, if so, which severity type.
If you add an alert based on the type of event generated, you should decide which events require an alert
You must provide the user names and email addresses of the users who receive the notification. You can also specify an SNMP trap as a mode of notification.
You can configure an alert to repeatedly send notification to the recipients for a specified time. You should determine the time from which the event notification is active for the alert. If you want the event notification to be repeated until the event is acknowledged, you should determine how often you want the notification to be repeated.
