Class ListFile.UntrackedPerformanceTracker

java.lang.Object

org.apache.nifi.processors.standard.ListFile.UntrackedPerformanceTracker

All Implemented Interfaces:

ListFile.PerformanceTracker

Enclosing class:

ListFile

public static class ListFile.UntrackedPerformanceTracker
extends Object
implements ListFile.PerformanceTracker

A PerformanceTracker that is capable of tracking which disk access operation is active and which directory is actively being listed, as well as timing specific operations, but does not track metrics over any amount of time. This implementation does not provide the ability to glean information such as which operations or files are taking the longest to operate on but uses very little heap.
