Thank you all for your replies. I have available for me Intel VTune Amplifier 2018 and Vampir 9.2.
So far i did rebuild HPX with -DHPX_WITH_APEX=ON and -DCMAKE_BUILD_TYPE=" RelWithDebInfo". I couldn't find a cmake or cmd line flag in the documentation how to enable OTF file creation. How is that done? @Hartmut: Do i need to do something extra to use VTune? A simple hotspot analysis looks promising, but is only showing me intern hpx function calls without any reference to my own code.
