title: Using logman to collect data
body: <p>I try to use logman instead of DDK tracelog for colecting *.etl data produced by my application that uses WPP but was not able to see any data (in *.etl) after reading the etl file and decoding *.fmt information by using traceview.</p>
  
  <p>What am I doing wrong? I generate *etl like this</p>
  
  <p>logman start "Session" -o "Trace.etl" -p "{28EE579B-CF67-43b6-9D19-8930E7AAA131}" -ets
  logman stop "Session"  -ets</p>
  
  <p>When opening with traceview the generated Trace.etl it shows not errors only that there is no collected data there.</p>
  
  <p>EDIT: I specify that I registered my generated *.mof file using mofcompiler on the system and that by using traceview directly I can see data.</p>
