Arguments
- veryshort
- Target takes less than 1 minute to run.
- short
- Target takes between 1 and 15 minutes to run.
- medium
- Target takes 15 minutes to 3 hours to run.
- long
- Target takes more than 3 hours to run.
Default
- short
- This is appropriate for a target that runs for 1 to 15 minutes.
Actions Modified
Description
If your target runs 15 minutes or longer, or if it runs
less than one minute, use the
target-duration
action-option to set a different duration
type. The
collect
or
collect-with
action uses this value to adjust the sampling
interval, which determines how much data is collected. For longer-running
targets, the sampling interval is greater (less frequent) to reduce the amount
of collected data. For very short-running targets, the sampling interval is
smaller (more frequent). For hardware event-based analysis types, a multiplier
applies to the configured Sample After value.
This option is deprecated. Use the
option instead.
Example
Perform a Hotspots analysis using a medium sampling
interval that is appropriate for targets with a duration of 15 minutes to 3
hours.
