I’m interested in detailed information about ongoing subscriptions on my server, so I enabled the sessionDiagnostics boolean parameter when starting the server. While the SubscriptionDiagnosticsArray components are available, only few variables actually contain values different from null. In particular, the “MonitoredItemCount” reports “null”.
How can I make the server fill in all variables of the SubscriptionDiagnosticsArray?
Thanks,

Hi,
Enabling diagnostics is the correct way to do it. If everything is not filled then, then there is a bug in the SDK.
You could try to check different diagnostics object, i.e. one under the session or subscription, not the node which should have whole array of them. The reason is that I’m not sure if we managed to get the array diagnostic working. Because the way diagnostics work in UA, the same diagnostic information should be in 3 different places, i.e. array of structures, strucutres in subnodes, parts of the structure in subnodes etc. there might still be some linking that is not working properly at the moment.
Will do more checking on next week 🙂

Hi Bjarne,
just to add a little more detail: the MonitoredItemCount in the struct is “0”; the value “null” is on the component variable. All this is read with UAExpert 1.3.1, in case the problem is on the client side
