Display Instances

Display Instances is a standard configuration interface to allow users to manage Display Instances, which can be used to show a custom name for a metric Instance, or for associating a metric Instance on a physical device to a virtual device.

Refer to the Standard Configuration Interface guide for details on interacting with the grid and form.

This user interface calls REST methods from api/metric/displayInstances.

To open this interface, from the main navigation menu, select Configuration, then Metrics, and then Display Instances.

Form Fields

• Display

  • Device - Device that will have the custom instance associated to it. It must be the same as the source device or a virtual device.

  • Instance Custom Name - Instance name to be displayed.

• Source

  • Device - Source device of the metric instance.

  • Metric Instance - Metric instances available for display.

Best Practices

Display instances have some limitations. The possible associations and their validity are listed below.

• Valid associations:

  • If Display -> Device and Source -> Device are the same physical device, the metric Instance is considered to have a custom name, and is what will be used for display purposes in the UI.

  • If Display -> Device is set to a virtual device and Source -> Device is a physical device, the metric instance from the physical device will be displayed for the virtual device.

• Invalid associations:

  • Source -> Device can never be set to a "Virtual" device.

  • Display -> Device and Source -> Device can not be two different physical devices.

  • If Display -> Device is set to a virtual device, Source -> Device can only be set to the physical device that is set as the parent device.
