The Statistics Configuration configures the statistics service usable by satellites in the configuration group. It provides is an optional service.

On Statistics Configuration may be present in a configuration group to configure the optional statistics service.

The statistics service is a fast and buffered service for collecting data from the satellite to the server. But it is ...

... write only - satellite can not read any data collected
... bufferd: on connection to server lost the satellite buffers the data local and writes it through on connection regain.
... fills a dump, fixed structured db-table in server-db. Report generation is to be done.
