If the Publishing status in the Configurator displays a red dot, publishing is inactive. In this situation, you may want to check the operational status of the replication processes. To do this from the Historian Agent Configurator:
-
Select the Publishing link.
-
The link opens the Detailed Process Status window, which displays the status of four processes necessary to replicate data to CONNECT data services: the Supervisor, System Platform Adapter, Replication Configuration, and Replication processes.
-
When you are finished checking the statuses of these processes, select Close.
Note: you can also check the status of these processes in the Operations Control Manager Control's Log Viewer and in the Windows Task Manager.
