VTune: Export all timeline data

wcon55 — Fri, 28 Feb 2025 13:20:22 GMT

Hello,

Let's say I ran a Microarchitecture Exploration in VTune (2025.0) on a Windows 11 (24H2) machine and wanted to recreate the graph view at the bottom of the "Event Count" Tab with external tools. For that I would need an export of all relevant data but do not know how to get that.

Actually, I care about more data than is shown at any given time in the timeline. Ideally, I would be able to export a normal CSV file containing:

All scheduling decisions (logical core/thread) and reasons.
All EHFI / Thread Director data
CPU Utilization data, if possible (what is currently running / is it inactive / etc.)
Core Type, if possible

To be clear: I do not want to get some aggregate report but ideally a series of precisely timestamped events. I do not care if the file is huge or needs external processing so long as the data I get is intelligible.

The closest I have gotten is with this command:

vtune -report exec-query -rep-knob row-by="/GenericCoreType/GenericCore/HWContext/GenericThread/HWFeedbackClass" -rep-knob column-by="CPUTime" -r <results_dir>

Unfortunately, it does not actually produce a timeline of anything. I have also tried the timeline and time report types but only ever get bins out when I want a series of events.

Additionally but separately from my primary concern of getting this working, I have tried a variety of commands including this:

vtune -report timeline -r <results_dir> -report-knob column-by=Core -report-knob group-by=Thread

which consistently yielded the error: "Unknown error has happened in timeline data provider."

Thanks for your help.

This is related to report customization, VTune supports some customization for report generation. For your case, we need to investigate and give you update.

如何自定义生成报告，有详细的教程吗

想要生成包含源代码占用时间，能够具体到行数，或者是否有对生成的sqlite-db中的原始数据库是否有具体的数据库的表定义和字段说明

Hi wcon55,

Microarchitecture Exploration has many options which we can enable by selecting the + (Customize the copy of the selected options) to get details about memory bound, stacks, Kernel, User tasks, events and context switches. In order to get the the details about the CPU utilizations and functions then run the hotspots and while running the report use the options like "callstacks" and "gprof-cc".
