Method Detail

criticalityByCost

public static CriticalCostPerExecutionPolicy criticalityByCost(float yellowPct,
                                               float redPct)

PIs are considered critical if their execution costs exceeds a certain limit. Limits can be defined per priority.

Parameters:

yellowPct - The percentage of the "target cost per execution" parameter a process with priority LOW must exceed to be considered critical.

redPct - The percentage of the "target processing time" parameter a process with priority HIGH must exceed to be considered critical.

Returns:

Instance of CriticalCostPerExecutionPolicy with the given thresholds
