ProcDump is a command-line utility whose primary purpose is monitoring an application for CPU spikes and generating crash dumps during a spike that an administrator or developer can use to determine the cause of the spike. ProcDump also includes hung window monitoring (using the same definition of a window hang that Windows and Task Manager use), unhandled exception monitoring and can generate dumps based on the values of system performance counters. It also can serve as a general process dump utility that you can embed in other scripts.

Using ProcDump

usage: procdump [-a] [[-c|-cl CPU usage] [-u] [-s seconds]] [-n exceeds] [-e [1 [-b]] [-f <filter,...>] [-g] [-h] [-l] [-m|-ml commit usage] [-ma | -mp] [-o] [-p|-pl counter threshold] [-r] [-t] [-d <callback DLL>] [-64] <[-w] <process name or service name or PID> [dump file] | -i <dump file> | -u | -x <dump file> <image file> [arguments] >] [-? [ -e]

-aAvoid outage. Requires -r. If the trigger will cause the target to suspend for a prolonged time due to an exceeded concurrent dump limit, the trigger will be skipped.
-bTreat debug breakpoints as exceptions (otherwise ignore them).
-cCPU threshold at which to create a dump of the process.
-clCPU threshold below which to create a dump of the process.
-dInvoke the minidump callback routine named MiniDumpCallbackRoutine of the specified DLL.
-eWrite a dump when the process encounters an unhandled exception. Include the 1 to create dump on first chance exceptions.
-fFilter the first chance exceptions. Wildcards (*) are supported. To just display the names without dumping, use a blank ("") filter.
-gRun as a native debugger in a managed process (no interop).
-hWrite dump if process has a hung window (does not respond to window messages for at least 5 seconds).
-iInstall ProcDump as the AeDebug postmortem debugger. Only -ma, -mp, -d and -r are supported as additional options.
-lDisplay the debug logging of the process.
-mMemory commit threshold in MB at which to create a dump.
-maWrite a dump file with all process memory. The default dump format only includes thread and handle information.
-mlTrigger when memory commit drops below specified MB value.
-mpWrite a dump file with thread and handle information, and all read/write process memory. To minimize dump size, memory areas larger than 512MB are searched for, and if found, the largest area is excluded. A memory area is the collection of same sized memory allocation areas. The removal of this (cache) memory reduces Exchange and SQL Server dumps by over 90%.
-nNumber of dumps to write before exiting.
-oOverwrite an existing dump file.
-pTrigger on the specified performance counter when the threshold is exceeded. Note: to specify a process counter when there are multiple instances of the process running, use the process ID with the following syntax: "\Process(<name>_<pid>)\counter"
-plTrigger when performance counter falls below the specified value.

Dump using a clone. Concurrent limit is optional (default 1, max 5).
CAUTION: a high concurrency value may impact system performance.

  • Windows 7   : Uses Reflection. OS doesn't support -e.
  • Windows 8.0 : Uses Reflection. OS doesn't support -e.
  • Windows 8.1+: Uses PSS. All trigger types are supported.
-sConsecutive seconds before dump is written (default is 10).
-tWrite a dump when the process terminates.
-uTreat CPU usage relative to a single core (used with -c).
As the only option, Uninstalls ProcDump as the postmortem debugger.
-wWait for the specified process to launch if it's not running.
-xLaunch the specified image with optional arguments. If it is a Store Application or Package, ProcDump will start on the next activation (only).
-64By default ProcDump will capture a 32-bit dump of a 32-bit process when running on 64-bit Windows. This option overrides to create a 64-bit dump. Only use for WOW64 subsystem debugging.
-?Use -? -e to see example command lines.

If you omit the dump file name, it defaults to <processname>_<datetime>.dmp.

Use the -accepteula command line option to automatically accept the Sysinternals license agreement.


Write a mini dump of a process named 'notepad' (only one match can exist):

    C:\>procdump notepad

Write a full dump of a process with PID '4572':

    C:\>procdump -ma 4572

Write 3 mini dumps 5 seconds apart of a process named 'notepad':

    C:\>procdump -s 5 -n 3 notepad

Write up to 3 mini dumps of a process named 'consume' when it exceeds 20% CPU usage for five seconds:

    C:\>procdump -c 20 -s 5 -n 3 consume

Write a mini dump for a process named 'hang.exe' when one of it's Windows is unresponsive for more than 5 seconds:

    C:\>procdump -h hang.exe hungwindow.dmp

Write a mini dump of a process named 'outlook' when total system CPU usage exceeds 20% for 10 seconds:

    C:\>procdump outlook -p "\Processor(_Total)\% Processor Time" 20

Write a full dump of a process named 'outlook' when Outlook's handle count exceeds 10,000:

    C:\>procdump -ma outlook -p "\Process(Outlook)\Handle Count" 10000

Write a MiniPlus dump of the Microsoft Exchange Information Store when it has an unhandled exception:

    C:\>procdump -mp -e store.exe

Display without writing a dump, the exception codes/names of w3wp.exe:

    C:\>procdump -e 1 -f "" w3wp.exe

Write a mini dump of w3wp.exe if an exception's code/name contains 'NotFound':

    C:\>procdump -e 1 -f NotFound w3wp.exe

Launch a process and then monitor it for exceptions:

    C:\>procdump -e 1 -f "" -x c:\dumps consume.exe

Register for launch, and attempt to activate, a modern 'application'. A new ProcDump instance will start when it activated to monitor for exceptions:

    C:\>procdump -e 1 -f ""

               -x c:\dumps Microsoft.BingMaps_8wekyb3d8bbwe!AppexMaps

Register for launch of a modern 'package'. A new ProcDump instance will start when it is (manually) activated to monitor for exceptions:

    C:\>procdump -e 1 -f ""

               -x c:\dumps Microsoft.BingMaps_1.2.0.136_x64__8wekyb3d8bbwe

Register as the Just-in-Time (AeDebug) debugger. Makes full dumps in c:\dumps.

    C:\>procdump -ma -i c:\dumps

See a list of example command lines (the examples are listed above):

    C:\>procdump -? -e
