Collection failure of General Exploration of vtune tutorial (VTune Amplifier 2018 trial version)

Hi, recently I followed the vtune tutorial as below to observe the hardware-related issues but I encountered some running error that I cannot figure it out. Hope someone here could give me certain suggestions to resolve it if you have had the same experience before.

https://software.intel.com/en-us/vtuneampxe_hwissues_lin_c

kernel: 3.10.0-514.26.2.el7.x86_64

OS: CentOS 7.3.1611

To collect the event-based metrics, I was asked to install the sampling driver for collecting hardware information as link below mentioned. The installation is very smooth and nothing error.

https://software.intel.com/en-us/vtune-amplifier-help-building-and-installing-the-sampling-drivers-f...

But in vtune tutorial of  General Exploration, the collection log showed me error message as below

"Collection failed. Apr 25 2018 15:08:59 Collection failed. The data cannot be displayed" 

and I have no idea what was wrong with my edition since I just went through all the steps of that tutorial. Does anyone meet the same problem as me? How did you resolve it?

Hello,

A VTune collection will create a directory (which we refer as result directory). It will have a default naming format as r000ge (the three numbers are auto-incrementing, and ge=general exploration).

Could you please upload that result directory so we can investigate what went wrong with General Exploration?

 

Also, how about a Basic Hotspot - do you see results displayed?

 

Thanks,

Hi. Shailen

Thanks for your reply and the basic-hot-spots/lock-and-wait are executed normally. But hardware-issues/disk-io failed to run due to some reasons that I cannot understand. I'm still finding some solutions(ex: perf tool) to take replace if possible.

Please take a look at the attached file. 

Btw,  this morning I ran it again and error message showed as below

"Collection failed

 Apr 26 2018 08:53:19 Collection failed. The data cannot be displayed.

 To profile kernel modules during the session, make sure they are available in the /lib/modules/kernel_version location

 Failed to execute sep process. Data collection is interrupted."
