As shown in the image above, this example is using SSH credential set. The first underline in the image is showing that SSH Status is true since we are using this form of authentication. Notice WMI Status is shown as false as well as SNMP, if a device was using those forms of credentials then they should be true instead. The second underlined part of this image is confirming that the credential set is working for this device and then continues below to show that the SSH audit is starting. Check the discovery log for this information after auditing your device to see if the credentials are being accepted with no issues.
