Detailed Description

Base class for all Sinks registering to the Monitoring Hub Should be extended by actual Sinks.

Deals with registration and manages selection of Entities Provides support for regular flushing of the Sink content. The AutoFlushPeriod property defines the interval. A value of 0 means no auto flush.

Actual Sinks extending this base class have to implement the flush method. This one has a boolean argument allowing to know whether it was called at a regular interval or a the end
