Defining general group alerts for attribute and capacity changes

You can define alerts that are triggered when the attributes or capacity of the resources that belong to a general group change.

To define a general group alert for attribute and capacity changes, complete these steps:

1. In the menu bar, select Groups > General Groups.
2. Right-click a general group in the list and click View Alert Definitions.
3. Click Edit Alert Definitions.
4. Click the type of resource that you want to set an alert for.
   You can set an alert for one or more of the attributes of the resource itself or its internal resources.
   For example, for a switch, you can set an alert for the attributes of the switch itself and for the attributes of the blades, inter-switch connections, and ports.
5. Click the category of the attributes that you want to alert for.

   Category	Description
   General	Attributes for the key properties of a resource, such as status, removals, discoveries, and data collection status.
   Capacity	Attributes for capacity statistics of a resource, such as available and used capacity, drive capacity, file systems, volumes, and pools, and reserved capacity.

6. To enable the alert for an attribute, click the check mark for the attribute.
7. Specify the conditions for generating an alert for an attribute.
   Conditions can include operators such as >=, or <=. Conditions can also include storage values and time values.
   For example, for a capacity attribute such as Available Capacity, you can specify that an alert is generated when the amount of available capacity on a resource's pools is less than or equal to 50 GiB.
   
   Tips:

   • Not all attributes require criteria for generating alerts. The category and type of an attribute determines whether you can specify criteria and the options that you can select.
   • Some attributes can use the operators such as is, is not, and contains. For example, for the Firmware attribute on a DS8000® storage system, select the operator contains. Then, in the value field, type R5 to be notified if the firmware is at the R5 level rather than at a later version such as R6.3, R6.2, or R6.3.
8. Assign a severity to an alert to help you more quickly identify and address the critical conditions that are detected on resources.
   The severity that you assign depends on the guidelines and procedures within your organization. Default assignments are provided for each alert.

   Option	Description
   Critical	Assign this severity to alerts that are critical and must be resolved. For example, assign a critical severity to alerts that notify you when the amount of available capacity on a file system falls below a specified threshold.
   Warning	Assign this severity to alerts that are not critical, but represent potential problems.For example, assign a warning severity to alerts that notify you when the status of a data collection job is not normal.
   Informational	Assign this severity to alerts that might not require any action to resolve and are primarily for informational purposes. For example, assign an informational severity to alerts that are generated when a new fileset is added to a storage system.

9. Optional: If you want to send email notifications of alert violations to contacts other than the policy contacts or global alert notification addresses, enter the email addresses in the Email Override field.
   Tip: If you enter an email address in the Email Override field, only that email address receives notifications for the alert. The following contacts do not receive notifications:

   • Any email addresses that are specified as policy contacts, if the alert is in an alert policy.
   • Any global email addresses that are specified for alert notifications. To view the global alert notification addresses, go to Settings > Notification Settings.
10. Optional: Click View Additional Options to specify how frequently you are notified of alerts.
    Use these settings to avoid triggering too many alerts for some conditions.
11. Optional: Click the icon to duplicate an alert.
    Use this action when you want to define another alert for the same attribute but with different criteria and settings.
    Duplicating alerts can be helpful in the following situations:

    • When you want to generate separate warning alerts and critical alerts for different conditions on the same attribute.
      For example, for a capacity attribute such as Available Capacity, you might want to define the following alerts:

      • Define a warning alert to be generated when the amount of available capacity on a resource's disks is less than or equal to 50 GiB.
      • Duplicate the alert, but this time, specify a critical severity when the amount of available capacity on a resource's disks is less than or equal to 10 GiB.
    • When you want to send alert notifications to different people based on the severity of an alert.

      In the previous example for the Available Capacity attribute, you can configure the notification settings so that warning alerts are sent to junior administrators, while critical alerts are sent to more senior administrators to resolve.
