The Cloud Quotas API represents dimensions as key-value pairs. The key is
the dimension name (for example, region). The value is the assigned value
for the dimension (for example, a region such as us-central1). Keys and values
are case sensitive.
For example, Compute Engine measures VM use by using different dimensions. The
region dimension measures the number of VMs you have in a given region.
Compute Engine also has a number of product attribute dimensions, including
gpu_family. The gpu_family dimension measures the number of GPUs of a
given family in your Google Cloud project.
View dimensions
You can view the dimensions for quotas and system limits by looking in the Google Cloud console, using the Google Cloud CLI, querying the REST API, or through client libraries. To view dimensions that you haven't specified a value for, use the gcloud CLI. Also use the gcloud CLI to view dimensions for quotas and system limits that don't have regional or zonal dimensions if your project doesn't already use the associated resource. This section shows how to view dimensions by using the console and by using the gcloud CLI.
Console
In the Google Cloud console, go to the IAM & Admin > Quotas & System Limits page:
The table on this page displays dimensions in the Dimensions column.
