How to log Current for a simulink model ?

I have a circuit which is a DC source and some resistors. I want to log current through each resistor. I read that i can right click a line and select add signal to be recorded. If i right click a resistor then Signal&ports submenu is grayed out If i select to log data to Simulation Data inspector then all values for a resistor are logged +power voltage , etc ...I want only currents .... Please help

Are you sure you are using Simulink blocks and not Simscape? A screenshot of your model might help.
