Remarks
This program is the common CSM form of executing a single device command and creating an inventory object based on the single command's output. This form is restricted to the preliminary device command list. It is a very simple form.
Inside of the device command on line 3 shell conditional logic is used. This is done to differentiate between devices able to connect to the domain google.com and not. If a device is unable to, the script assigns the parameter IsConnected=No to the device. Otherwise, it assigns the parameter IsConnected=Yes.
