monitoring point of total temperature

How to create it (total temperature versus step or timestep) during a transient simulation on ANSYS Fluent 12 software?

thanks.

I´m simulating on a solid only domain and my results show that the static temperatures have greater results than the total temperatures, for a transient simulation. Why of this? I used the ANSYS Fluent 12 software. When i use ANSYS CFX 12, there is no option to export, in ANSYS CFX Pre, the total temperature results. How to export the total temperature to ANSYS CFX Post 12?
