The time of the day (HH:MM) that the fragmentation check should be run
SchedulerDaysOfWeekMask
int
$Config/SchedulerDaysOfWeekMask$
Days Of Week mask
The day(s) that the fragmentation check should be run. The values for the days are Sunday (1), Monday (2), Tuesday (4), Wednesday (8), Thursday (16), Friday (32) and Saturday (64). To specify multiple days, add the values for the days together. For example, for Monday, Wednesday, and Friday, specify 42 (2+8+32).
FilePercentFragmentationThreshold
double
$Config/FilePercentFragmentationThreshold$
File Percent Fragmentation Threshold
If the "Use OS Recommendation" is set to "False" then this value will be used as the threshold for fragmentation levels.
UseOSRecommendation
bool
$Config/UseOSRecommendation$
Use OS Recommendation
This parameter determines whether the fragmentation level check will use the default threshold determined by the operating system or not. If this parameter is set to "False" then the value from "File Percent Fragmentation Threshold" will be used.
