FILE: sample_metrics_query.py
DESCRIPTION:
This sample demonstrates authenticating the MetricsQueryClient and retrieving the "Ingress"
metric along with the "Average" aggregation type. The query will execute over a timespan
of 2 hours with a granularity of 5 minutes.
USAGE:
python sample_metrics_query.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://docs.microsoft.com/python/api/overview/azure/identity-readme?view=azure-python#defaultazurecredential.
In this example, a Storage account resource URI is taken.
