- Displaying exception information from an event
- If a command produces events that contain errors, you may want to display the details of the exception information related to particular event in a nicely formatted way, analogically to what the
error?(shortened:er?) command does. To do so, determine the index eventIndex of the event in the sequence, and then enter the following command:events? eventIndex --!extractMember EventArgs.ErrorDescendInfos(shortened:ev? eventIndex -!xm EventArgs.ErrorDescendInfos). The resulting table starts with a row for the outmost exception, and the subsequent row(s) contain the inner exception(s), recursively. An error ID and the full error message is listed with each exception. - How can I enable the log (trace) entries from OPC UA stack and SDK with commands like uaClient or uaServer?
