Device Labels enable you to apply a label to each of the devices that your organization has registered with Kentik Detect (see Device Admin). The management of device labels in the Kentik Detect portal is discussed in the following topics:

About Device Labels

A device label is simply a property whose value is text. You can apply a label to one or more device to create a group of devices. The devices in a group would typically be (but are not required to be) alike in some way; a label allows you to refer to them all together rather than individually. Labels are not mutually exclusive, so you can apply multiple labels to any device.

Device labels are visible in the Device List on the Admin » Devices page and are also particularly useful when choosing devices to include in a query; you can now include devices based on their label rather than individually (see Devices Pane Settings). When a query is defined using a device label then the devices whose flow data will be included in the query are determined at run time based on which devices have that label. This means that if you refer to devices via labels when building components such as dashboards, saved views, reports, and saved filters then you can change the devices that a given component covers without going back and revising the component itself.

Note: If you change the group of devices to which a given label is applied (adding the label to or removing it from any device) then a query that uses that label will look at traffic from the revised group of devices across the entire time-range of the query, without regard to whether the label was or wasn't applied to any of those devices at any given point in that time-range.

Device Labels Page UI

The Device Labels page includes the following UI elements:

  • Filter field: Filters the Device Labels list to show only rows containing the entered text in the following columns: Name, Labels.
    Note: Any change to the Filter field will uncheck all checked rows in the Device Labels list.
  • Clear Labels button (active only when one or more checkboxes are checked in the Device Labels list): Removes all labels from any row of the Device Labels list whose checkbox is currently checked.
  • Apply Labels menu (active only when one or more checkboxes are checked in the Device Labels list): Click to drop down a menu listing all of your organization’s currently defined labels:
    - Any label that is already applied to a row that is checked in the Device Labels list will have a checkmark in the Apply Labels menu.
    - Click on an unchecked label in the menu to apply that label to all checked rows in the Device list.
    - Click on a checked label in the menu to remove that label from all checked rows in the Device list.
    - If you make no change to a given label in the menu (neither check nor uncheck it) there is no change with respect to that label in the checked rows of the Device list.
  • Show Unlabeled Devices button: Filters the Device Labels list to show only devices that have no labels (filter = “no label”). If the filter is already applied then instead the Show All Devices button is shown, which removes the “no label” filter.
  • Device Labels list: A table listing your organization’s currently defined device labels (see Device Labels List).
  • Add Label controls: Buttons and fields that enable you to add a label (see Add Label Controls).
  • Manage Labels controls: Buttons and fields that enable you to manage existing labels (see Manage Labels Controls).

    Note: Any change to the Filter field will uncheck all checked rows in the Device Labels list.
