Not able to extract performance data from .ETL file using xperf commands. getting error "Events were lost in this trace. Data may be unreliable ..."

Question

Not able to extract  performance data from .ETL file using xperf commands.
Xperf Commands:
xperf –i C:\TempFolder\Test.etl -o C:\TempFolder\BootData.csv  –a process
Getting following error after executing above command:
"33288636 Events were lost
in this trace. 
Data may be unreliable
This is usually caused
by insufficient disk bandwidth for ETW lo
gging.
Please try increasing the minimum
and maximum number of buffers
and/or
                the buffer size. 
Doubling these values would be a good first at
tempt.
Please note, though, that
this action increases the amount of me
mory
                reserved
for ETW buffers, increasing memory pressure on your sce
nario.
See "xperf -help start"
for the associated command line options."
I changed page size file but its does not work for me.
Any one have idea, how to solve this problem and extract ETL file data.

Answer 1

I want to mention one point here. I have total 4 machines out of these 3 machines above
commands working properly. Only one machine has this problem.<o:p></o:p>
Hi,
I consider that you can try to use xperf to collect the trace etl file and see if it can be extracted on this computer:
Refer to following articles:
