Redundant Overview

Note:

This tab is only available for redundant projects.

When Backend is in-proc, the connection line from NGA manager to backend is always grey.
When backend is out-of-proc, the connection line is green when a connection is established and red if there is no connection between the NGA manager and the backend.
When there is no connection between the projects of a redundant project, the elements of the unreachable project will be hidden (their state is not known).
For Buffers, see chapter Buffering Parameters.
