Sustainability metrics
MetricsHub enriches hardware data with energy usage metrics, such as hw.host.energy, hw.host.heating_margin, hw.host.power, to deliver an accurate assessment of a resource's carbon footprint. Visualized in user-friendly dashboards, these sustainability metrics offer a comprehensive understanding of the environmental impact of the IT infrastructure.
To ensure dashboards are properly populated, you must configure MetricsHub in the config/metricshub.yaml configuration file.
Configure the sustainability settings
To obtain the electricity costs and carbon footprint of your sites and the resources within them, follow these steps to configure the config/metricshub.yaml file:
- Configure the Site: Define the
siteattribute for your infrastructure. - Configure the Sustainability Metrics: Set up sustainability metrics, including carbon intensity, electricity cost, and Power Usage Effectiveness (PUE).
Step 1: Configure the site
Start by configuring the site attribute for your infrastructure. Having the site property allows dashboards to report the electricity costs and carbon footprint per site (e.g., per data center). This can be done differently depending on whether you have a highly distributed[1] or centralized[2] infrastructure.
Highly distributed infrastructure
For infrastructures with multiple distributed locations, configure the site under the attributes section of each resource group:
resourceGroups:
<resource-group-name>:
attributes:
site: <site-name>
resources:
<resource-id>:
attributes:
host.name: <hostname>
host.type: <type>
<protocol-configuration>
Example:
resourceGroups:
boston:
attributes:
site: boston
resources:
myBostonHost1:
attributes:
host.name: my-boston-host-01
host.type: storage
<protocol-configuration>
myBostonHost2:
attributes:
host.name: my-boston-host-02
host.type: storage
<protocol-configuration>
chicago:
attributes:
site: chicago
resources:
myChicagoHost1:
attributes:
host.name: my-chicago-host-01
host.type: storage
<protocol-configuration>
myChicagoHost2:
attributes:
host.name: my-chicago-host-02
host.type: storage
<protocol-configuration>
Centralized infrastructure
For a centralized infrastructure, configure the site directly under the main attributes section:
attributes:
site: <central-site>
resources:
myCentralHost1:
attributes:
host.name: my-central-host-01
host.type: storage
<protocol-configuration>
myCentralHost2:
attributes:
host.name: my-central-host-02
host.type: storage
<protocol-configuration>
Step 2: Configure the sustainability metrics
Next, configure the sustainability metrics section. Place this section either within each resource group for distributed infrastructures[1] or directly in the main metrics section for centralized infrastructure[2].
Example for distributed infrastructure
resourceGroups:
boston:
attributes:
site: boston
metrics:
hw.site.carbon_intensity: 230 # in g/kWh
hw.site.electricity_cost: 0.12 # in $/kWh
hw.site.pue: 1.8
resources:
myBostonHost1:
attributes:
host.name: my-boston-host-01
host.type: storage
<protocol-configuration>
myBostonHost2:
attributes:
host.name: my-boston-host-02
host.type: storage
<protocol-configuration>
Example for centralized infrastructure
attributes:
site: <central-site>
metrics:
hw.site.carbon_intensity: 230 # in g/kWh
hw.site.electricity_cost: 0.12 # in $/kWh
hw.site.pue: 1.8
resources:
myCentralHost1:
attributes:
host.name: my-central-host-01
host.type: storage
<protocol-configuration>
myCentralHost2:
attributes:
host.name: my-central-host-02
host.type: storage
<protocol-configuration>
Metric details
hw.site.carbon_intensityis the carbon intensity in grams per kiloWatthour. This information is required to calculate the carbon emissions of your site. The carbon intensity corresponds to the amount of CO₂ emissions produced per kWh of electricity and varies depending on the country and the region where the data center is located. See the electricityMap Web site[3] for reference.hw.site.electricity_costis the electricity price in the currency of your choice per kiloWattHour. This information is required to calculate the energy cost of your site. Refer to your energy contract to know the tariff by kilowatt per hour charged by your supplier or refer to the GlobalPetrolPrices Web site[4]. Make sure to always use the same currency for all instances of MetricsHub on all sites to allow cost aggregation in your dashboards that cover multiple sites.hw.site.pueis the Power Usage Effectiveness (PUE) of your site. By default, sites are set with a PUE of 1.8, which is the average value for typical data centers.
You can either hardcode a value or configure MetricsHub to retrieve that information.
