Constructor Detail

PerformanceCriticalityPolicy

public PerformanceCriticalityPolicy(float lowPriorityCriticalPct,
                            float normalPriorityCriticalPct,
                            float highPriorityCriticalPct)

Method Detail

criticalityByDuration

public static PerformanceCriticalityPolicy criticalityByDuration(float lowPriorityCriticalPct,
                                                 float normalPriorityCriticalPct,
                                                 float highPriorityCriticalPct)

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

Parameters:

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

normalPriorityCriticalPct - The percentage of the "target execution time" parameter a process with priority NORMAL must exceed to be considered critical.

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

Returns:
