Define the **Element Type** properties shown below, so that Single Connect can identify the OS of the discovered instances:

1. Navigate to **Device Management** > **Element Type**.
2. Click the **Options** button of the related element type and click **Show Properties**.
3. Set the **device.import.gcp.element.type.pattern**, **device.import.azure.gcp.protocol**, and **device.import.gcp.ssh.username** properties.

| **device.import.azure.gcp.protocol**       | Mandatory.&#xD;<br />This property is used to determine the default access method for the discovered instances.&#xD;                                                                                  |
| **device.import.gcp.element.type.pattern** | Mandatory.&#xD;<br />The pattern can be defined as multiple in one element.&#xD;<br />This pattern is checked against the “Image” description of the instance in order to determine the OS type.&#xD; |
| **device.import.gcp.ssh.username**         | Mandatory for log in. Not required for device import.&#xD;<br />This username is used as the default log in credential.&#xD;                                                                          |
| **device.import.gcp.port.number**          | Optional.&#xD;<br />Devices are imported with the defined port number value. If this value is not set, a default port number is used, such as 22 for SSH.&#xD;                                        |

:::hint{type="info"}
Defining a new Element Type for each OS type is required, in order for Single Connect to autodetect devices.&#x20;
Ex: CentOS Linux, Ubuntu Linux, etc.
