EnergyWise terminology
This topic applies only to the following products:
SolarWinds Observability Self-Hosted
NPM
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.
- In SolarWinds Platform Web Console resources, the Power Level may be designated as the EnergyWise Level or the EW Level.
- Some Cisco IOS versions report EnergyWise levels as values
1-11
instead of0-10
. In SolarWinds NPM 10.1.2 and later versions, the levels are automatically corrected. IOS's on some devices are not affected by this issue.
