Setting a "browse chunk" size:
<pre>
uaClient 
set IsolatedParameters.SessionParameters.MaximumReferencesPerBrowseNode [Int32]400
browse opc.tcp://localhost:49320 nsu=KEPServerEX;ns=2;s=Simulation.Functions
</pre>

== Command: uaClient subscribe ==

<pre>
OpcCmd -i
uaClient
subscribe opc.tcp://opcua.demo-this.com:51210/UA/SampleServer nsu=http://test.org/UA/Data/;i=10849
</pre>

Obtaining server condition statistics:
# Enter <code>uaClient --ConnectionMonitoring</code>.
# Enter <code>subscribe opc.tcp://opcua.demo-this.com:51210/UA/SampleServer nsu=http://test.org/UA/Data/;i=10849</code>.
# Optionally terminate the command prematurely by pressing {{Style=keyboard|X}}.
# Wait for approx. 10 seconds.
# Enter <code>events?</code>, or shortened: <code>ev?</code>. Note the index of the last event (in the "[]" column).
# Enter <code>events? --!extractElement <nn> --!extractMember EventArgs.Statistics.StateDictionary</code>, or shortened: <code>ev? -!xe <nn> -!xm EventArgs.Statistics.StateDictionary</code> where <nn> is the index of the last event, taken in previous step.
