Add failover capability so I can run a pair of connectors that will failover to the backup if the active is unavailable
This is critical for us to be able to use PI connectors for production data.
There is a desire to add a failover Wonderware Historian for an existing primary Wonderware Historian for redundancy. However, with PI Connector for Wonderware's inability to detect an issue with the primary Wonderware Historian and automatically switch to the failover Wonderware Historian, the value of adding the failover Wonderware Historian is diminished.

It's just a must have. This used to be in the previous (OPC-UA) version 1.3.x, but in the 2.x version it's not available anymore...
How can i explain this to a customer? Use an older version that does not receive updates anymore?
Use the version 1.3.x but then accept there is no source-level failover?
Ronald Bechaalany commented
A customer has recently requested this specifically for the PI Connector for Wonderware Historian
this should be possible for all connectors (e.g. UFL)
Michael Kreideweis commented
Yes, we'd also need failover for UFL connector, because the datasource (REST client) does not buffer any data.
