Tracing in Dynamics AX 4 and 2009
Цитата:
Once, I also saw the ”Fail to start ETW tracing session: return code is 112” error message. It was caused by incorrect setting of tracefilesize in Dynamics AX configuration in registry. By default, this setting is set to 10000. So, on attempt to start tracing, WMI Event tracing subsystem checks that target drive for log file has 10000 MBytes available (10Gbytes actually). If available space is less than 10Gbytes, attempt to start tracing fails with the error message mentioned. I recommend to set this setting to something like 1000, because actually Trace Parser tools tends to choke on attempt to import event file larger than several hundreds megabytes.
