Hi there,
I was told I could view boot-time ETW messages but I couldn’t find any
information how to do that.
Currently I can’t see ETW message until I started a trace session on the
target system. I’d played with the wmitrace.dll dbgext for sometime but was
intimidated by the ‘symbol not found’ no matter what symbols I’ve loaded.
Has anybody got it working? Am I missing something obvious?

To use this feature requires the component to use the “Global Logger”,
so there are three things you must do.
-Build your driver to be global logging aware.
Add the following definition to the driver code
-Enable your driver’s control GUID on the Global logger
Under the GlobalLogger registry key
(HKLM\System\CurrentControlSet\Control\WMI\GlobalLogger), add a key for
your GUID. Enclose the control GUID in braces ( { } ).
The Tracelog -start command adds the GlobalLogger key to the registry.
The ControlGUID key establishes the driver as provider for the Global
Logger trace session
To configure your provider add Flags as REG_DWORD value, and Level as a
REG_DWORD value.
Restart the system. This starts the global logger trace session, and the
driver logs to it every time you restart the system.
When you are done, delete your GUID key from the registry or Set the
value of the Start Entry in the GlobalLogger key to 0

But I don’t know how to redirect the messages to KD on my host as I did in a

Thanks Jose.
I guess I want to see the output in my host debugger BEFORE the target is
fully up since my driver might have crashed the system before I can do
anything on the target. Is there any option to configure the global logger
to put message to KD by default?

The macro that is auto generated for tracing by WPP (DoTraceMessage) is
defined in such a way that if you’ll do
#define WPP_DEBUG KdPrint
Every call to that macro will translate to an event trace AND a debugger
print.
This feature is not documented anywhere though, I figured it out myself from
reading the .tmh files,
So I guess it might disappear in future versions.

Ok, I think my problems were:
My driver starts far earlier than the storage adapter does, I guess no
message could be written to the log at that point of time.
The logged message kept getting thrown to the GlobalLogger (log file)
until I do ‘tracelog -start MYGUID -kd’ on the target machine.
I still think that there must be a way to solve problem 2). Can anybody shed
some light?
I’d better keep DbgPrint(Ex) in my driver for now. Can the logger store the

I was told I could view boot-time ETW messages but I couldn’t find any
information how to do that.
Currently I can’t see ETW message until I started a trace session on the
target system. I’d played with the wmitrace.dll dbgext for sometime but was
intimidated by the ‘symbol not found’ no matter what symbols I’ve loaded.
Has anybody got it working? Am I missing something obvious?

In release builds I use ETW and in debug builds I use DbgPrint. This way I
get the best of both worlds. When I need boot up info (which In my case is
not very often) I pass out the debug version like I did before, but in the
vast majority of cases I just have them enable logging, repro the problem,
disable and email me the log.
I had to modify the sources file like so (I use w2k method for 32 bit, and
the w2003 way for 64bit)
!if “$(DEBUG_BUILD)” == “1”
!else
!if “$(_BUILDARCH)” == “IA64”
RUN_WPP=$(SOURCES) \
-km -dll\
-func:Debug(LEVEL,(MSG,…))
!else
!if “$(_BUILDARCH)” == “AMD64”
RUN_WPP=$(SOURCES) \
-km -dll\
-func:Debug(LEVEL,(MSG,…))
!else
!ifndef DO_NT_4
RUN_WPP=$(SOURCES) \
-km -dll\
-gen:{km-w2k.tpl}*.tmh \
-func:Debug(LEVEL,(MSG,…))
!endif ## nt4
!endif ## AMD64
!endif ## ia64
!endif ## debug
Thanks,
Rob

Subject: RE: [ntdev] ETW at boot time???
Ok, I think my problems were:
My driver starts far earlier than the storage adapter does, I guess no
message could be written to the log at that point of time.
The logged message kept getting thrown to the GlobalLogger (log file)
until I do ‘tracelog -start MYGUID -kd’ on the target machine.
I still think that there must be a way to solve problem 2). Can anybody shed
some light?
I’d better keep DbgPrint(Ex) in my driver for now. Can the logger store the
message in memory and write it to disk later after the FSD is up?
Thanks,
Calvin

Thanks Jose.
I guess I want to see the output in my host debugger BEFORE the target is
fully up since my driver might have crashed the system before I can do
anything on the target. Is there any option to configure the global logger
to put message to KD by default?
Thanks again,
Calvin

use your controlGUID to start the logger, that will switch tracing to your
logger.

Ok, but it didn’t work for me in the first place. As I stepped into the
WppInitGlobalLogger, I found it trying to access WMI\GUID instead of
WMI{GUID}
mydrv!WppInitGlobalLogger+0x1b3:
f738f3f3 6a00 push 0x0
kd> db GRegValueName
f796ab50 57 00 4d 00 49 00 5c 00-47 00 6c 00 6f 00 62 00 W.M.I..G.l.o.b.
f796ab60 61 00 6c 00 4c 00 6f 00-67 00 67 00 65 00 72 00 a.l.L.o.g.g.e.r.
f796ab70 5c 00 61 00 63 00 63 00-37 00 66 00 32 00 65 00 .a.c.c.7.f.2.e.
f796ab80 31 00 2d 00 66 00 61 00-32 00 34 00 2d 00 34 00 1.-.f.a.2.4.-.4.
f796ab90 38 00 64 00 62 00 2d 00-62 00 64 00 63 00 30 00 8.d.b.-.b.d.c.0.
f796aba0 2d 00 65 00 36 00 61 00-63 00 62 00 64 00 30 00 -.e.6.a.c.b.d.0.
f796abb0 66 00 30 00 32 00 38 00-31 00 00 00 bb 00 00 c0 f.0.2.8.1
So I removed the enclosing braces, then my driver can send output into the
%system32%\Logfiles\wmi\trace.log and I can use traceview to see the logged
messages.
But I don’t know how to redirect the messages to KD on my host as I did in a
non-global log session. I’ve tried tracelog -start GlobalLogger -kd…but
doesn’t seem to work. Any idea?
Thanks,
Calvin

To use this feature requires the component to use the “Global Logger”, so
there are three things you must do.
-Build your driver to be global logging aware.
Add the following definition to the driver code
TraceLog -start GlobalLogger
-Enable your driver’s control GUID on the Global logger
Under the GlobalLogger registry key
(HKLM\System\CurrentControlSet\Control\WMI\GlobalLogger), add a key for your
GUID. Enclose the control GUID in braces ( { } ).
The Tracelog -start command adds the GlobalLogger key to the registry.
The ControlGUID key establishes the driver as provider for the Global Logger
trace session
To configure your provider add Flags as REG_DWORD value, and Level as a
REG_DWORD value.
Restart the system. This starts the global logger trace session, and the
driver logs to it every time you restart the system.
When you are done, delete your GUID key from the registry or Set the value
of the Start Entry in the GlobalLogger key to 0
