Configuring Alerts

HPE Aruba Networking Central allows you to configure the following alerts:

• Access Point Alerts

• Bridge Alerts

• Gateway Alerts

• Switch Alerts

• Third-Party Switch Alerts

To configure alerts, complete the following steps:

1. In the HPE Aruba Networking Central landing page, click the menu icon to open the Menu page.

2. In the Alert Management card, click Manage.

   The Alert Management page displays the alerts in list view.

   You can view the following information in the alerts list view table:

   Table 1: Edit Alerts Parameter Details

   Parameter	Description
   Name	Displays the scope of the alert.
   Category	Displays the scope category of the alert.
   Device	Displays the device type such as Access points, Switches, or Gateways.
   Labels	Select a label(s) from the drop-down list to limit the alert to a specific label. You can select multiple labels. In the Labels drop-down list, you can perform the following: Select All—Select the check box to select all the labels. Search—Search for a label using keywords. View Selection—Click to view the selected labels. Create Label—Create a new label. To create a new label, click Create Label, enter a name in the Label Name field, and then click Create.
   Status	Displays whether the alert is enabled or disabled.
   Origin	Displays the origin of the alert. For example, System or Custom.
   Inherits From	Indicates the source or hierarchy level from which an alert configuration is derived. Hierarchy levels and override rules: Global Level—Represents the default configuration applied system-wide. All sites and devices automatically inherit these global alert settings unless explicitly modified. Site Level—When an alert configuration is defined at the site level, it overrides the global configuration for that specific site. This allows the users to tailor alert thresholds or conditions based on the operational requirements of individual sites. Device Level—When an alert configuration is applied directly at the device level, it takes precedence over both the site-level and global configurations. This provides the highest degree of customization, ideal for unique or critical devices that require specialized monitoring.

3. In the Alert Management page, complete one of the following steps:

   • To filter the alerts based on Status, click Enabled or Disabled.

   • You can use the search bar to search for an alert by keywords. For more information, see Searching for Alerts in the List View.
