 Event attributes are also much more detailed and show EventID, Level, Task, Opcode, and Keywords properties.Users can filter event logs by one or more criteria or by a limited XPath 1.0 expression, and custom views can be created for one or more events.Using XPath as the query language allows viewing logs related only to a certain subsystem or an issue with only a certain component, archiving select events and sending traces on the fly to support technicians.
