Description
The
duration
option is required for system-wide collection,
and specifies the duration for collection (in seconds). System-wide collection
occurs when the target is not specified on the command line when collection is
initiated. It also can be used with when the target is specified, but you want
to set a specific duration for data collection.
Example
This command performs system-wide collection of
Hotspots for 20 seconds.
vtune -collect hotspots -knob sampling-mode=hw -duration=20In this example, the
sample
target on Linux* is specified for a Threading
analysis, but collection is limited to 60 seconds in duration.
vtune -collect threading -duration=60 -- /home/test/sample
