About notification rules

Notification rules are accessed from within the Policy Editor and are used to notify users when a policy (firewall policy or NAT policy) is changed or when a percentage of the maximum supported configuration objects is reached. The notifications are configured using notification rules and are delivered through email, such an email is referred to as a notification email. Notification rules can be useful for administrators who wish to be notified when policies are changed, or who wish to notify others of such changes. Notifications can also be sent based on shared resources used by policies.

About Notification Email

There are two kinds of notification email that can be sent using notification rules:

  • If a Policy Notify rule type is selected, the notification email lists what specified policies have changed, possibly including any changed shared resources.
  • If a Limit Notify rule type is selected, the notification email lists what specified limits have been reached. The limits can include device limits, object limits or both.
    • The limit for a device is determined by the license for that device. The email contains the number of devices and the percentage of devices used, based on the maximum number of devices.
    • The limit for objects is a total number of objects for all devices being managed by the BIG-IQ system. Shared objects, such as virtual servers, only count as a single object even if they are used multiple times. The email contains the number of objects for all devices being managed and the percentage of objects used, based on the maximum number of objects.

Adding and scheduling notification rules

Use the Notification Rules screen of the Policy Editor to add and schedule a new notification rule.

    Email Recipients Specify information about one or more email recipients.
    • In the Name field, specify a name for the recipient.
    • In the Email Address field, specify the email address of the recipient.

    To add another recipient, click the ( + ) plus sign and supply the Name and Email Address fields for that recipient.

    To remove a recipient, click the (X) to the right of the email recipient.

  4. If you specified the Rule Type as Policy Notify, specify the appropriate values for the following fields on the Policy Notify tab.
    Field Description
    Available Firewall Policies Select the firewall policy the rule should monitor and notify you when it changes, then click Add . The selected policy is added to the list of firewall policies below the Available Firewall Policies field.
    Notify on Dependent Objects Determines whether or not dependent objects, such as shared resources, are also monitored by the rule. By default this option is selected, indicating that shared resources should also be monitored.
    Available NAT Policies Select the NAT policy the rule should monitor and notify you when it changes, then click Add. The selected NAT policy is added to the list of policies below the Available NAT Policies field.
    Notify on Dependent Objects Determines whether or not dependent objects, such as shared resources, are also monitored by the rule. By default this option is selected, indicating that shared resources should also be monitored.

    You can also add firewall policies or NAT policies by dragging them from the Shared Resources area and dropping them on to the Drop Firewall Policies here to add to the list area or dropping them on the Drop NAT Policies here to add to the list area.

    To delete a policy from the list, click the X to the right of the Notify on Dependent Objects option.

  5. If you specified the Rule Type as Limit Notify, specify the appropriate values for the following fields on the Limit Notify tab.
    Field Description
    Device Limit Notification Select this check box to be notified when the BIG-IQ system reaches a specified limit.
    Device Limit Thresholds Specify the device limit thresholds at which a notification email is sent. A device limit is a percentage of the number of BIG-IP devices your BIG-IQ system is managing. You can set up to three limits that are each a percentage of the limit amount by modifying the percentage amount in each of the three device limit threshold fields. For example, if your BIG-IQ system is licensed to handle 10 BIG-IP devices, you would go over the threshold of 49% when 5 BIG-IP devices were being managed.
    Object Limit Notification Select this check box to be notified when a specified object limit is exceeded.
    Object Limit Thresholds Specify the object limit thresholds at which a notification email is sent. You can set up to three limits that are each a percentage of the limit amount by modifying the percentage amount in each of the three object limit threshold fields.

    As more operations occur with more BIG-IP devices, the number of objects in use by the BIG-IQ system grows. The maximum number of objects supported varies depending on the BIG-IP device configuration.
