I am working on an OPC UA Client, and I want to display the OPC UA Server's ServerStatusDataType information to the user.

I have read the forum thread below:

https://forum.unified-automation.com/viewtopic.php?f=18&t=2539&p=5505&hilit=serverstatus#p5505

It mentions that the "the client SDK does a cyclic read on the ServerStatus". Does the SDK make available the information obtained during this read? Or do I need to set up a MonitoredItem to get the ServerStatusDataType?

Yours,

The SDK only does a cyclic read on the "State", "SecondsTillShutdown" and "ShutdownReason" members of the ServerStatus, those are available via getters:

If you need the complete ServerStatus Variable you have to set up your own monitoredItem/read.
