How to get CPU utilization timeline data in intel-vtune using command line?

Question

My goal is to generate CPU utilization timeline data from the command line in Vtune. Is there any way to do it?

I can collect Vtune data for hotspots using the following command:

vtune -collect hotspots -result-dir r000hs program

Using GUI, I can see the CPU utilization timeline as shown in the picture below:

However, I want to plot the data with high resolution and merge it with some other data to put it in a PDF. Can this data be generated from the command line?

I found a few commands to do it, but none generated this timeline data. For example,

vtune -report hotspots -r r000hs -report-output output

only generates the functions with overall runtime.

Answer 1

The CPU utilization timeline data can be obtained using the below command after running the analysis:

$ vtune -report timeline -r <result_dir_name> -report-knob column-by=CPUTime -report-knob bin-count=xx

The number of bins for the above command can be obtained by changing the bin-count report knob which accepts whole numbers greater than zero:

For example:

$ vtune -report timeline -r r000hs -report-knob column-by=CPUTime -report-knob bin-count=20

The column-by report knob can accept the following based on the type of analysis performed using Intel® VTune™ Profiler to generate timeline reports:

where UMS is user mode sampling, HWEBS is hardware event-based sampling and EMON, Perf, SEP, TPSS, and VTSS are Intel® VTune™ Profiler data collection drivers.

Note: Task and TaskType are only valid with ITT API user tasks.
