Specified by:

maxSpaceSize in interface IgfsMetrics

Returns:

Maximum IGFS local space size.

secondarySpaceSize

public long secondarySpaceSize()

Get used space in bytes used in the secondary file system.

This is a global metric.

Specified by:

secondarySpaceSize in interface IgfsMetrics

Returns:

Used space in the secondary file system or 0 in case no secondary file system is configured.
