how to generate a timeline report with the right column-by=x

[shuoli01]

I am trying to generate time view from the existing sampling r000hpc by using command line.

% vtune -report timeline -r r000hpc

 vtune: Using result path `/root/r000hpc'
vtune: Executing actions 75 % Generating a report Error: the required argument "column-by" is missing. Please provide it in the form: "-report-knob column-by=<value>"
vtune: Executing actions 100 % done
vtune: Error: 0x40000028 (Reporter error)

vtune -report timeline -report-knob column-by=10 -r r000hpc
vtune: Using result path `/root/r000hpc'
vtune: Executing actions 75 % Generating a report
Invalid column-by query (10) is provided. The query is either unknown or not applicable to the current result.
vtune: Executing actions 100 % done
vtune: Error: 0x40000023 (User input error)

My question is what's the column-by number, how to set it to create a timeline report?

Hi ,

We were able to reproduce the issue from our end.

The following is analysis type / data collector: valid column-by values for HPC Performance Characterization Analysis on TGL NUC with Ubuntu 20.04.6 LTS

Analysis Type	Columns Used
HPC SEP	CPI, CPUTime, InstructionsRetired, Task, TaskTime, TaskType, Vectorization
HPC VTSS	CPI, CPUTime, InstructionsRetired, Task, TaskTime, TaskType, Vectorization

For example, you have to give the below CLI command and it will show the results

vtune -report timeline -r r000hpc -report-knob column-by=CPUTime

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