FILE: sample_metric_definitions.py
DESCRIPTION:
This sample demonstrates listing all the metric definitions of a resource.
USAGE:
python sample_metric_definitions.py
Set the environment variables with your own values before running the sample:
1) METRICS_RESOURCE_URI - The resource URI of the resource for which the metrics are being queried.
This example uses DefaultAzureCredential, which requests a token from Azure Active Directory.
For more information on DefaultAzureCredential, see https://learn.microsoft.com/python/api/overview/azure/identity-readme?view=azure-python#defaultazurecredential.
In this example, an Event Grid account resource URI is taken.
