  How to collect SCVMM traces

  Wednesday, July 21, 2010 12:47 AM

  For general information about troubleshooting VMM 2012, such as collecting traces and logging information, see VMM 2012 General Troubleshooting Guide (http://go.microsoft.com/fwlink/?LinkID=211124) on the Microsoft Download Center.  .

  Before Collecting a DebugView Trace

  1.       Install DebugView on the SCVMM server, the host in question, and/or the Web server (for troubleshooting self-service portal issues).

  2.       Save the following code into a text file and name it "odsflags.cmd":

  @echo off

  echo ODS control flags - only trace with set flags will go to ODS

   

  if (%1)==() goto :HELP

  if (%1)==(-?) goto :HELP

  if (%1)==(/?) goto :HELP

   

  echo Setting flag to %1...

  reg ADD "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Tracing\Microsoft\Carmine" /v ODSFLAGS /t REG_DWORD /d %1 /f

  echo Done.

  goto :EXIT

   

  :HELP

  echo Usage: odsflags [flag], where flag is

  echo TRACE_ERROR = 0x2,

  echo TRACE_DBG_NORMAL = 0x4,

  echo TRACE_DBG_VERBOSE = 0x8,

  echo TRACE_PERF = 0x10,

  echo TRACE_TEST_INFO = 0x20,

  echo TRACE_TEST_WARNING = 0x40,

  echo TRACE_TEST_ERROR = 0x80,

   

  :EXIT

  3.       Save the following code into a text file and name it "odson.reg":

  Windows Registry Editor Version 5.00

   

  [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Tracing\Microsoft\Carmine]

  "ODS"=dword:00000001

  4.       Save the following code into a text file and name it "odsoff.reg":

  Windows Registry Editor Version 5.00

   

  [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Tracing\Microsoft\Carmine]

  "ODS"=dword:00000000

  5.       Copy the three files created above, odsflags.cmd, odson.reg, and odsoff.reg, to the machines that DebugView will be used on.

  6.       Run the following commands at an elevated Command Prompt:

  odson.reg

  odsflags.cmd 255

  (If you need to collect traces for both VMM Server and the host or the Web server, make sure to run these commands on all of these computers).

  Collecting a DebugView Trace

  1.       Open DebugView as an administrator and ensure that both Capture Win32 and Capture Global Win32 are selected on the Capture menu item. You should be able to see tracing from the VMM components showing up in DebugView. (If you need to collect traces for both VMM Server and the host, make sure to do these steps on all of these computers).

  2.       Restart the Virtual Machine Manager Service on the SCVMM server by running the following commands at an elevated command prompt:

  net stop vmmservice

  net start vmmservice

  3.       Restart the Virtual Disk Service by running the following commands at an elevated command prompt:

  net stop vds

  net start vds

  4.       Restart the Virtual Machine Manager Agent service on the host by running the following commands at an elevated command prompt:

  net stop vmmagent

  net start vmmagent

  5.       Restart the IIS service on the Web server by running the following command at an elevated command prompt:

   iisreset

  6.       Reproduce the issue.

  7.       After reproducing the issue, save the output from the DebugView to a text file for analysis.

  Important:

  Turn off tracing after collecting the data by running the following command at a Command Prompt: odsoff.reg

   

   

  The format of a DebugView trace differs from that of an ETL trace since DebugView captures all Win32 application activity and, if selected, Kernel mode activity. If saved as a text file, it may be opened in other tools such as TextAnalysisTool.net or Trace32.
