Collect performance data remotely with the Intel® VTune™ Amplifier collectors (for example, SEP collector or Intel SoC Watch collector) or Linux* Perf* collector, import this data to the VTune Amplifier project, and view the data in the graphical or command line interface.
Currently the following data formats can be imported:
*.tb6/*.tb7 (sampling raw data files collected with the low-level SEP collector)
*.perf (Perf data files)
*.csv (external data collection files in the predefined format)
*.pwr (processed Intel SoC Watch files with Energy analysis data collected on Android* or Linux* OS)
*.sww1 (Intel SoC Watch files with Energy analysis data collected on Windows* OS)
Prerequisites for importing a *.perf file with event-based sampling data collected by the Linux* Perf tool:
Run the Perf collection with the predefined command line options:
For application analysis:
>perf record -o <trace_file_name>.perf --call-graph dwarf -e cpu-cycles,instructions <application_to_launch>
For process analysis:
>perf record -o <trace_file_name>.perf --call-graph dwarf -e cpu-cycles,instructions <application_to_launch> -p <PID> sleep 15
where the -e option is used to specify a list of events to collect as -e <list of events>; --call-graph option (optional) configures samples to be collected together with the thread call stack at the moment a sample is taken. See Linux Perf documentation on possible call stack collection options (for example, dwarf) and its availability in different OS kernel versions.
Note
The Linux kernel exposes Perf API to the Perf tool starting from version 2.6.31. Any attempts to run the Perf tool on kernels prior to this version lead to undefined results or even crashes. See Linux Perf documentation for more details.
To import files into a VTune Amplifier project from GUI:
- Select the
Import option using any of the following options:
Open a project where you want to locate the imported result, click the
menu button and select
Import Result....
Click the
Import Result button on the toolbar.
The Import window opens.
Note
To resolve symbol information for the imported data, the VTune Amplifier uses search directories specified for the current project. To view/modify the search directories, click the Configure Project... button on the product toolbar and click the Binary/Symbol Search or Source Search button on the right.
To reduce the size of the imported result, consider using the Remove raw collector data after resolving the result option available from Options... > Intel VTune Amplifier version > General tab. This option makes the result file smaller but prevents future re-finalization.
You can run a custom data collection (with a third-party collector or your own collection utility) in parallel with the VTune Amplifier analysis run, convert the collected data to a *.csv file and import the this file to the VTune Amplifier project using the Import from CSV GUI option or -import CLI option. You may also choose to use the Custom collector option of the VTune Amplifier to run your custom collection directly from the VTune Amplifier.
