Method Detail

init

public void init()

Description copied from interface: BaseSource

Clear out the metrics and re-prepare the source.

Specified by:

init in interface BaseSource

Overrides:

init in class BaseSourceImpl

setRIT

public void setRIT(int ritCount)

Description copied from interface: MetricsAssignmentManagerSource

Set the number of regions in transition.

Specified by:

setRIT in interface MetricsAssignmentManagerSource

Parameters:

ritCount - count of the regions in transition.

setRITCountOverThreshold

public void setRITCountOverThreshold(int ritCount)

Description copied from interface: MetricsAssignmentManagerSource

Set the count of the number of regions that have been in transition over the threshold time.

Specified by:

setRITCountOverThreshold in interface MetricsAssignmentManagerSource

Parameters:

ritCount - number of regions in transition for longer than threshold.

setRITOldestAge

public void setRITOldestAge(long ritCount)

Description copied from interface: MetricsAssignmentManagerSource
