Logman creates and manages Event Trace Session and Performance logs and supports many functions of Performance Monitor from the command line.
Syntax
Logman.exe is located in the C:Windows folder. Known file sizes on Windows 10/8/7/XP are 61,440 bytes (50% of all occurrences), 343,552 bytes or 81,920 bytes. The logman.exe file is a file with no information about its developer. To download this script, download the latest version here. This script is intended to collect the Exchange default logging data from the server in a consistent manner to make it easier to troubleshoot an issue when large amounts of data is needed to be collected. Jul 15, 2016 Logman logs bulk transfers in 32 bit Windows 7 but doesnt log bulk transfers in 64 bit of Windows 7. Im working with logman in Windows 7 PC. I used these commands. I used these commands in a 32 bit machine and 64 bit machine.

A common question that we get asked is how to pull the information that Resource Monitor (ResMon.exe) provides.
In ResMon, we are able to see the following five (5) tabs:
Overview
CPU
Disk
Network
Memory
CPU
Processes
Services
Associated Handles
Associated Modules
Memory
Processes
Physical Memory
Disk
Processes with Disk Activity
Disk Activity
Storage
Network
Processes with Network Activity
Network Activity
TCP Connections
Listening Ports
How do you capture these set of data for consumption?
All of these are ETW data that is collected and outputed on a nice visual tool.
To be able to view the ETW providers that are running when you fire off Resmon, just open Perfmon.
Performance --> Data Collector Sets --> WDC.GUID
Note: Where the guid is different for different systems.
Inside of the of WDC.GUID 'Event Trace Session', we see that the following ETW providers are collected:
{B2CA89D8-FAC8-4759-A0C7-2FAD1FD0E716}
0xffffffffffffffff 0xffffffff
Microsoft-WIndows-Kernel-Disk
0xffffffffffffffff 0xffffffff
Microsoft-Windows-Kernel-File
0x10 0xffffffff
Note: 0x10 denotes Kernel_File_Keyword_Filename
Microsoft-Windows-Kernel-Network
0xffffffffffffffff 0xffffffff
Microsoft-Windows-Kernel-Process
0x20 0xffffffff
Note:0x20 denotes WinEvent_Keyword_Thread
And their buffer size is set this way:
64KB Buffer size
16 Minimum buffers
38 Maximum buffers
Stream mode:
Real Time
So, this is looking good for me since ETW providers are something that I could collect using many different on/off (Controller/Consumer) tools such as:
TraceLog.exe (Controller) (SDK)
TraceRpt.exe (Consumer) (SDK)
Logman (Controller)(built-in)
XPerf (Controller) (WPT)
XPerfView (Consumer) (WPT)
In this segment, I'll just go thru setting up via Logman.
Start, Run, CMD (Run as admin)
logman.exe /?
logman start WDC -p {B2CA89D8-FAC8-4759-A0C7-2FAD1FD0E716} 0xffffffffffffffff 0xff -bs 64 -nb 16 38 -max 10 -ets
logman start WDC -p Microsoft-WIndows-Kernel-Disk 0xffffffffffffffff 0xff -bs 64 -nb 16 38 -max 10 -ets
logman start WDC -p Microsoft-Windows-Kernel-File 0x10 0xff -bs 64 -nb 16 38 -max 10 -ets
logman start WDC -p Microsoft-Windows-Kernel-Process 0x20 0xff -bs 64 -nb 16 38 -max 10 -ets
Note:
-mode <trace_mode> Event Trace Session logger mode. For more
information visit -
http://go.microsoft.com/fwlink/?LinkID=136464
-ln <logger_name> Logger name for Event Trace Sessions.
-[-]p <provider [flags [level]]> A single Event Trace provider to enable.
The terms 'Flags' and 'Keywords' are
synonymous in this context.
-pf <filename> File listing multiple Event Trace providers
to enable.
-[-]rt Run the Event Trace Session in real-time mode.
-bs <value> Event Trace Session buffer size in kb.
-nb <min max> Number of Event Trace Session buffers.
-[-]max <value> Maximum log file size in MB or number of
records for SQL logs.
-o <path|dsn!log> Path of the output log file or the DSN and
log set name in a SQL database. The default
path is '%systemdrive%PerfLogsAdmin'.
-[-]v <nnnnnn|mmddhhmm> Attach file versioning information to the
end of the log name.
-ets Send commands to Event Trace Sessions
directly without saving or scheduling.
But we don't want to run four (4) different trace sessions to collect the one (1) WDC trace session.
I went ahead and created a new file in Notepad called WDC_Providers.txt which contained the following 4 lines:
{B2CA89D8-FAC8-4759-A0C7-2FAD1FD0E716} 0xffffffffffffffff 0xff
Microsoft-WIndows-Kernel-Disk 0xffffffffffffffff 0xff
Microsoft-Windows-Kernel-File 0x10 0xff
Microsoft-Windows-Kernel-Process 0x20 0xff
logman start WDC -pf 'C:PerflogsWDC_Providers.txt' -bs 64 -nb 16 38 -max 10 -ets
which works fine.
Now, we just need to clean up a little bit such as putting the output directory of the file, and the trace mode.
logman start WDC -pf 'C:PerflogsWDC_Providers.txt' -bs 64 -nb 16 38 -max 10 -mode newfile -o c:PerfLogsoutput%d.etl -ets
Windows 7 Update
If you want to stop
Logman Windows 7
logman stop WDC -ets
Logman Windows 7 Download
You should have an .etl file in c:perflogs.
