DESCRIPTION:
    This sample demonstrates authenticating the LogsQueryClient and querying a single query.
USAGE:
    python sample_logs_single_query.py
    Set the environment variables with your own values before running the sample:
    1) LOGS_WORKSPACE_ID - The first (primary) workspace ID.

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.

**Note** - Although this example uses pandas to print the response, it's optional and
isn't a required package for querying. Alternatively, native Python can be used as well.
