All the database connections in Ignition use the Store and Forward system. This system offers a number of benefits over other systems that log directly to the database. The main benefits are: data loss prevention and enhanced performance.

Click on Store & Forward from the left menus.
The Store & Forward Connections page is displayed showing each store-and-forward engine along with the current throughput and capacity of its Memory Buffer and Disk Cache.
You can click on Details under the Store and Forward Engines section to refresh and update the displayed values.
