Revive the 7.9 gateway status tab information on remote OPC-UA client connections to the Ignition OPC-UA server, where you could see the session ID, remote client name, remote address, number of subscriptions and last activity. You could also drill down into the details of a connection and see what was being polled and at what rate.

The remote connection information is currently only available if diagnostics are turned on on the OPC-UA status tab, and these eat up a lot of CPU resources to even enable. There is no way still in 8.1 to see the specific tag information being polled though and at what speed. This is critical for troubleshooting especially when a device connection sees an unexpected jump in overload percentage.
