UA Sample Server log file and NodeId help |OPC UA Implementation: Stacks, Tools, and Samples|Forum|OPC Foundation

Does Sample Server have the option to have a log file and how to turn it on? I managed to write my own OPC Client on the base of  NetCoreConsoleClient. I have managed to connect and change value Int16 on the Prosys OPC UA Simulator Server. On UA Sample Server i'm able to connect but can't change value with my Client. 

Only difference I can see is on Prosys they are using NodeId (ns=3;s=Int16) and on UA Sample Server (ns=2;i=10219). 

I'm using this syntax for Node addressing:

NodeId node = new NodeId("ns=3;s=Int16"); 

Thanks
