(CLion) Thread dump tools not visible

I would like to save the state of my program and perform debugging by exploring the variable contents from the saved memory image. I can't find the dump button (with an icon of a camera), or the dump tab, or the "Get thread dump" command under Run, as described here:

Do I have to enable some option, or am I missing something? I am using CLion 2016.3 on Ubuntu 16.04.

Thanks!
