Now I try to follow the tutorial steps for analyzing disk I/O metrics https://software.intel.com/en-us/vtune-amplifier-disk-io-tutorial-linux
But on Analysis Type page it shows error message as below so that I cannot start collection process
"Ftrace collection is not possible due to a lack of credentials. Make sure you have read/write access to debugFS. You may either run the analysis with root privileges (recommended) or follow the configuration instructions provided in the Software Event Library help topic."
For read/write access to debugFS, I typed
$> mount | grep debugfs, and it showed
$> debugfs on /sys/kernel/debug type debugfs (rw, relatime), seems I have read/write access to it, right?
- How to know I have root privileges ? I've been added to the group but same message popped up
- where is the related configuration instruction as message mentioned above (Software Event Library help topic). Could you please share the link with me, thanks.

Please run ample-gui as root.
I encountered this problem at first, and can run well as root.
Good luck!
