Hyperview has power sensors tied to each location that are rolled up into this dashboard widget that allows users to easily read the location power information at a glance. If the values of these sensors are zero, or empty, then that typically means the proper setup for the location power sensors has not been achieved. Below we will outline what each sensor means and how to properly set them up in Hyperview to rollup this data to the widgets.

IT Energy:

This value refers to the power consumption of all IT equipment in the location. Hyperview can calculate this from various perspectives depending on what equipment is being discovered and monitored. The location properties page allows you to select the IT Energy Setting to use for effective calculation.

How to Setup IT Energy Sensors:

1. Navigate to the properties page for the selected location. (Location > Information > Properties)

2. Locate the Power property for IT Energy Setting. Drop down the selector for that property to see the available options.
   
   

   1. Sum IT Energy Based on UPS Output Total Power - Tells Hyperview to read all of the Output Total Power sensors that are monitored for UPS devices within the location and sum them together to generate the value for IT Energy.
      

   2. Sum IT Energy Based on PDU/RPP Output Total Power - Tells Hyperview to read all of the Output Total Power sensors that are monitored for PDU/RPP devices within the location and sum them together to generate the value for IT Energy.
      

   3. Sum IT Energy Based on Rack Total Power - Tells Hyperview to read all the Rack Total Power sensors associated to all racks in the location and sum them together to generate the value for IT Energy.

      1. If this option is chosen, make sure that the Rack Total Power Setting property is also chosen properly for each rack in the location. The options here include Sum Power Providing Device Output Total Power, Sum Power Consuming Devices, or Sum Linked Power Sensors. If the correct option is not chosen for each rack, then it may lead to inaccuracies in the IT Energy calculation.

3. Select the option that best suits your location parameters and Hyperview insights to monitored data from devices.

Once you have followed this configuration setup, the next sensor calculation cycle should generate a sensor value for IT Energy at the location.

Total Facility Power:

Total Facility Power references the total power consumed in the location regardless of device type. This includes building management equipment and facility infrastructure such as CRAC and CRAH units, In Row Cooling devices, Chillers, etc... This value is defined by the level of monitored data read from power providing devices within Hyperview, and the proper sensor linking and setup is required for a value to be calculated.

How to Setup Total Facility Power Sensors:

Unlike the IT Energy Setting property that is required to setup on each location in order to calculate the value for IT Energy, Total Facility Power requires power sensors from power providing devices to be linked to the correct locations.

1. Identify the power providers for the location. Typically these are going to be floor mounted PDUs, RPPs, UPS, Busways, or Utility Breakers (with power meters).

2. Navigate to each power providing device for the location in Hyperview and open the Sensors page. (Power Providing Device > Information > Sensors)

3. Identify the sensor you would like to rollup to the location level for Total Facility Power. Usually either a direct sensor called Output Total Power, or a calculated sensor for Output Total Power is available if the devices are actively discovered and monitored.

4. Click the Link button for that sensor, then select the corresponding location from the location picker to assign that power sensor to the location.
   
   

Once you have linked all the power sensors for the given location, the Total Facility Power sensor for that location will be calculated automatically during the next calculation cycle.

PUE (Power Usage Effectiveness):

PUE is the ratio that expresses the efficiency of a particular location based on energy usage between computing equipment versus facility overhead. The closer the PUE rating is to 1 (one), the more efficient the infrastructure.

Once the IT Energy and Total Facility Power sensors have been setup and are reporting accurate values, then Hyperview will automatically use those values to generate a PUE rating for the location. The standard calculation for PUE is as follows:
