**To get the connectivity information for a Greengrass core**

The following ``get-connectivity-info`` example displays the endpoints that devices can use to connect to the specified Greengrass core. Connectivity information is a list of IP addresses or domain names, with corresponding port numbers and optional customer-defined metadata. ::

    aws greengrass get-connectivity-info \
        --thing-name "MyGroup_Core"

Output::

        "ConnectivityInfo": [
            {
