    Authentication credentials
    The examples below assume your InfluxDB host, organization, and token are provided by either the active influx CLI configuration or by environment variables (INFLUX_HOST, INFLUX_ORG, and INFLUX_TOKEN). If you do not have a CLI configuration set up or the environment variables set, include these required credentials for each command with the following flags:

    --host: InfluxDB host
    -o, --org or --org-id: InfluxDB organization name or ID
    -t, --token: InfluxDB API token
