When running opreport when there is no profile data available, it will display a message something like the following:
Using /root/oprofile_data/samples/ for samples directory.
opreport error: No sample file found: If using opcontrol for profiling,
try running 'opcontrol --dump'; otherwise, specify a session containing
sample files.
But as of release 1.0.0, the opcontrol tool is no longer included in oprofile. This message needs to be updated to reflect that.
This bug was opened in error. I saw this message on a machine that was still running a version 0.9.9 oprofile. In fact, the message already has been updated to remove references to opcontrol. The bug will rejected and closed.
