EnergyWise terminology

The following terms and concepts are provided in the EnergyWise MIB and used within EnergyWise resources in the SolarWinds Platform Web Console.

Domain

The EnergyWise MIB includes a field for labeling groups of EnergyWise-capable devices, or entities, as members of a designated domain. In SolarWinds NPM, a single domain consists of all monitored EnergyWise entities defined as neighbors.

Entity

Any network device, including switches, IP phones, and other components connected to Power over Ethernet (PoE) ports on EnergyWise-capable devices, that either draws power from another network device or supplies power to another network device.

Importance Level

The Importance is a priority value ranging from 1 to 100 that is assigned to both EnergyWise entities and EnergyWise policies. The higher the value, the more important the device, and the less likely it is to be changed by energy policy modifications.

When a policy application is attempted, the importance levels of the policy and the selected entity are compared. If the policy importance level is greater than or equal to the entity importance level, the policy is applied to the entity and the entity power level is changed. If the importance level of the entity is greater than the importance levels of the policies applied, the entity power level will remain unchanged.

For example, an IP phone assigned an importance level of 80 is operating at a power level of 8. Policy A5, to change entity power levels to 5, has an importance of 50, and Policy B10, to change entity power levels to 10, has an importance of 95. If Policy A5 is applied to the phone, the phone will continue to operate at power level 8. However, if Policy B10 is applied to the phone, the phone power level changes to 10 in keeping with applied Policy B.

The importance value may be used to exempt specific entities from policy changes. For example, if all your emergency phones are on a single switch, the switch should never go into standby mode. To ensure that the switch hosting your emergency phones never goes into standby mode, set the switch importance to 100 so all policies with an importance of 99 and lower will have no effect on the emergency phone switch.

Keywords

The EnergyWise MIB provides for the identification of individual entities with unique labels. When an entity is initially configured, keywords may be added in series, as a string of words separated by commas without spaces, as shown in the following example:

Keyword1,Keyword2,Keyword3

Name

A user-friendly identifier for an EnergyWise entity or domain that may be assigned in the EnergyWise MIB when the entity or domain is configured. The default name for a switch is the hostname, and the default name for a Power over Ethernet (PoE) port is a shortened version of the port name. EnergyWise name values cannot include spaces. Modifying the EnergyWise name does not change the hostname of the device or the port name on the device. Omit spaces and refrain from using asterisks (*) in your name designations. Valid characters include alphanumeric characters and symbols, including #, (, %, !, or &.

Neighbor

Any two EnergyWise entities defined within the same domain are neighbors. Neighbors are capable of communicating EnergyWise events including the issuance of energy management directives.

Policy Level

The Policy Level is the power level of the policy that is currently applied to the selected entity.

Power Level

The Power Level is a designation of the amount of power an EnergyWise entity is allowed to draw, based on the policies currently acting upon it. The following table details available levels with category labels and icon colors.

Level	Label	Category	Color	Color Code
10	Full	Operational (1)	Red	FF0000
9	High
8	Reduced		Yellow	FFFF00
7	Medium
6	Frugal		Green	00FF00
5	Low
4	Ready	Standby (0)	Blue	0000FF
3	Standby
2	Sleep		Brown	A52A2A
1	Hibernate
0	Shut	Nonoperational (-1)	Black	000000
