Class ThreadProfilingEvent

java.lang.Object

org.apache.flink.runtime.event.job.AbstractEvent

org.apache.flink.runtime.profiling.types.ProfilingEvent

org.apache.flink.runtime.profiling.types.VertexProfilingEvent

org.apache.flink.runtime.profiling.types.ThreadProfilingEvent

All Implemented Interfaces:

IOReadableWritable, ManagementEvent

public class ThreadProfilingEvent
extends VertexProfilingEvent

Through this interface it is possible to access profiling data about the CPU utilization of the corresponding execution thread during its execution.
