Timeline Report

Like the Timeline window in the Intel® VTune™ Profiler user interface, the Timeline report provides information about a metric which changed over time. This is a tabular report where each row displays the average metric value in each time interval.

For example, this command generates a timeline report that captures the CPU Utilization section highlighted in the Timeline pane below: 

vtune -result-dir <result_path> -report timeline -report-knob column-by=CPUTime -report-knob bin-count=5

When you run the command, you see the following information: 

vtune: Using result path `C:\VTune\Projects\sample (matrix)\r005hs'
vtune: Executing actions 75 % Generating a report

Generate a Timeline Report from an Existing Result

Run this command: 

vtune -result-dir <result_path>
      -report timeline
      -report-knob column-by=<metric name>
    [ -report-knob sort-column-by=<metric name> ]
    [ -report-knob group-by=<grouper name> ]
    [ -report-knob bin-count=<30 by default> ]
    [ -report-knob start=<0 by default> ]
    [ -report-knob end=<end of collection by default> ]
    [ -report-knob time-format=<seconds|milliseconds|events> ]
    [ -report-knob object-names=True|False by default ]
    [ -report-knob query-type=interval|... ]

where:

  • <metric name> is the metric information you want. For example, CPUTime, OvertimeBandwidth, ContextSwitches, Task, PMUEventCount/PMUEventType etc.

  • <grouper name> is an optional name given to a grouper. During data collection, every metric on the timeline gets detected within a context. The metric is then attributed to the context. You use this context as the <grouper name> to group metric actions. Some examples of <grouper name> are Thread, UncorePackage, Task etc. Each instance of the <grouper name> generates an output table for that collection of metric actions. For example, if a parallel application runs on eight threads, setting group-by=Thread generates eight timeline reports. To see the overall behavior of the metric over time, do not set <grouper name>.

Example: Timeline Report for CPU Time

This example generates a timeline report for the r000hs result of a Hotspots analysis. The timeline report shows CPU Time utilization over 30 intervals: 

vtune.exe -r r000hs -report timeline -report-knob column-by=CPUTime

Example: Timeline Report for CPU Time within Time Range

In this example, a timeline report is generated from the r006ue result of a Microarchitecture analysis. The data is collected between the second and fifth seconds. The data collected during these three seconds is presented over 50 intervals of time. 

vtune -r r006ue -report timeline -report-knob column-by=CPUTime -report-knob start=20000000000 -report-knob end=50000000000 -report-knob bin-count=50

Example: Timeline Report as a CSV File

When you collect a significantly large volume of data, consider exporting the timeline report to a CSV file for easier data management.

In this example, a timeline report generated from the r008hs result (of a Hotspots analysis) is saved as a CSV file (r008hs_timeline.csv). The collected data is split into 1000 intervals of time. 

vtune -r r008hs -report timeline -report-knob column-by=CPUTime -report-knob bin-count=1000 -format=csv -csv-delimiter=semicolon -report-output r008hs_timeline.csv

The contents of r008hs_timeline.csv contain: 

timeBin;Bin Start Time;Bin End Time;CPU Time:Self
0;2.000;2.060;583.614
1;2.060;2.120;596.239
...

Example: Timeline Report of PMU Core Events Grouped by Threads

Run this command to generate a timeline report that groups PMU core events by threads and sorts the groups by event counts. 

vtune -r <result dir> -report timeline -report-knob group-by=Thread -report-knob sort-column-by=PMUEventCount -report-knob column-by=PMUEventCount/PMUEventType

Example: Timeline Report of PMU Uncore Events Grouped by Packages

Run this command to generate a timeline report that groups PMU uncore events by packages and sorts the groups by uncore event counts. 

vtune -r <result dir> -report timeline -report-knob group-by=UncorePackage -report-knob sort-column-by=UncoreEventCount -report-knob column-by=UncoreEventCount/UncoreEventType

Example: Timeline Report of Context Switches per Thread

Run this command to generate a timeline report of context switches per thread, using a time format of millisecond 

vtune -r <result dir> -report timeline -report-knob query-type=interval -report-knob group-by=Thread -report-knob sort-column-by=ContextSwitchCount -report-knob column-by=ContextSwitches -report-knob bin-count=1000000000 -report-knob time-format=millisecond

Example: Timeline Report of Tasks per Thread

Run this command to generate a timeline report of tasks per thread and also displays the names of the tasks. 

vtune -r <result dir> -report timeline -report-knob query-type=interval -report-knob group-by=Thread -report-knob sort-column-by=TaskTime -report-knob column-by=Task -report-knob object-names=True -report-knob bin-count=1000000000
