```
public int getInputTuplesDequeuedTotal()
```
    Deprecated.
    
    Returns the total number of input tuples consumed by this operator since the StreamBase Server was started. If this number is less than the number of tuples enqueued to the input stream, then tuples are being queued up faster than the operator can consume them.
