>
> To probe a stat in {{StorageStatistics}}, users can use the
> {{StorageStatistics#isTracked()}} API. Currently {{DFSOpsCountStatistics}}
> implements this function wrongly. {{S3AStorageStatistics}} borrowed the same
> idea and also has the same error.
> # The {{isTracked()}} is not correctly implemented. I believe this was an
> omission in code.
> # {{isTracked()}} checks a stat with operation symbol (instead of enum name).
> {{getLongStatistics()}} should return LongStatistics iterators with symbol as
> name, instead of the enum variable name. Or else,
> {{isTracked(getLongStatistics().next().getName());}} returns false. This will
> lead to confusion.
