anomaly-detection
Command Line Analysis

Use Anomaly Detection to identify performance anomalies in frequently recurring intervals of code like loop iterations. Perform fine-grained analysis at the microsecond level.

This is a PREVIEW FEATURE
. A preview feature may or may not appear in a future production release. It is available for your use in the hopes that you will provide feedback on its usefulness and help determine its future. Data collected with a preview feature is not guaranteed to be backward compatible with future releases.

Syntax

vtune

-collect anomaly-detection [-knob <knobName=knobValue
>] [--] <target
>

Knobs:

ipt-regions-to-load

Specify the maximum number (10-5000) of code regions to load for detailed analysis. To load details efficiently, maintain this number at or below 1000.

Default value :

1000

Range :

10-5000

max-region-duration

Specify the maximum duration (0.001-1000ms) of analysis per code region.

Default value :

100 ms

Range :

0.001-1000ms

For the most current information on available knobs (configuration options) for Anomaly Detection analysis, enter:

Example

This example shows how to run Anomaly Detection analysis on a sample application called

myApplication

. The analysis runs over 1000 code regions, analyzing each region for 300 ms.

vtune -collect anomaly-detection -knob ipt-regions-to-load=1000 -knob max-region-duration=300   -- /home/test/myApplication

If you want to transfer the collected data to a different system for analysis, you must archive the result by moving all related binaries to the result folder. After Anomaly Detection analysis completes, run this command:
