Download source files - 5 Kb "When people talk, listen completely. traceFailedRequestsLogging. For collecting native heap information, we enable stack tracing and the collection of heap traces (ETW) which are very verbose and will create large diagsession files. NET trace facilities and then discusses different methods to customize. This functionality provides a way to trace and log events that are raised by user mode applications and kernel mode drivers. Investigate why 53% (21,213) events were lost during data collection. Since the logs are a finite 100MB in size, once we reach that limit, events from the beginning of the current or "live" ETL log will be truncated to make room for events at the end of the log. information from ETW, supplier of Thread events from Microsoft: information on thread creation/completion, information on threads started (PID, TID, size of stack, priorities and allocation of CPU resources, I/O resources, memory pages between threads, stack address, address of init function, address of Thread Environment Block (TEB), Windows.
