The installation works fine however when I attempt to run vtlec the eclipse browser run fine for a few moments before comming up with the following errors after closing.

I use First User Wizard ,and get the

error:

"Connection to server lost"

This error might not be related to VTune per se. Can you please try to see if the vTune command line works/ Something like this:

./bin/vtl activity -c sampling -d -o "-cal no -ec (en='CPU_CLK_UNHALTED.CORE' :sa 28330000)(en='INST_RETIRED.ANY' :sa 28330000) -sm ebs -si 1" -app /the/path/to/your/app/to/sample,"parameters list for your app separated by commas" run

The sampling after value (sa) parameter might need to be adapted for your CPU frequency.

The tb5 file (with the sampling data) should be in your_vtune_directory/global_data/vtserver_/sampling.tb5.

Please let us know if this works.

Regards,

Nick
