com.amazonaws.kinesisvideo.demoapp.debug.StatsWriter

All Implemented Interfaces:

AutoCloseable

public class StatsWriter
extends Object
implements AutoCloseable

Writes the current heap memory count to the file (bytes), along with a timestamp. This class provides a way to monitor memory allocation of a KinesisVideoClient by periodically writing the allocation size to a specified file in a csv-format.

This class will spawn a new thread to record the metrics, and terminate that thread once close() is called.
