windows server dump文件

1. mini dump:

***** 需要包含 dbghelp.dll 库

****mini_dump.h文件：

// reference:https://msdn.microsoft.com/zh-cn/library/windows/desktop/ee416349(v=vs.85).aspx

#ifndef mini_dump_h__
#define mini_dump_h__

namespace minidump
{
void MiniDumpBegin(const char* app_name, const char* app_version);
}

#endif // mini_dump_h__

mini_dump.cpp文件：

#include "mini_dump.h"

#include <windows.h>
#include <shellapi.h>

#include <string>

// Is dbghelp.h dbghelp.lib dbghelp.dll windows build-in?
#include <dbghelp.h>
#pragma comment (lib,"dbghelp.lib")

// Visual Studio 2005 compatible
#define snprintf(buf,len, format,...) _snprintf_s(buf, len,len, format, __VA_ARGS__)

namespace minidump
{
// needn‘t delete
std::string* app_name = 0;

std::string* app_version = 0;

// "c:\folder1\xxx.exe" to "c:\folder1\"
std::string GetDirectory(const std::string& execution)
{
std::string path("");
size_t pos = execution.find_last_of("\\");
if (pos != std::string::npos)
path = execution.substr(0, pos + 1);
return path;
}

// Generage dump file to avoid file name collisions
std::string GetDumpFileMark()
{
SYSTEMTIME system_local_time;
GetLocalTime(&system_local_time);

char file_name[MAX_PATH];

snprintf(file_name, MAX_PATH, "%s%s-%04d%02d%02d-%02d%02d%02d-%ld-%ld.dmp",

system_local_time.wHour, system_local_time.wMinute, system_local_time.wSecond,
GetCurrentProcessId(), GetCurrentThreadId());

return file_name;
}

// Generate dump file whole name in GetModuleFileName()‘s directory
// Like: F:\reference\project\TestMiniDump\VsProject\build\Debug\dump\20161015-110026-8552-9344.dmp
std::string GetDumpFileName()
{
char file_path[MAX_PATH];
GetModuleFileName(NULL, file_path, MAX_PATH);

std::string path = GetDirectory(file_path);

path += "dump\\";

std::string file_mark = GetDumpFileMark();

path += file_mark;

return path;
}

MINIDUMP_EXCEPTION_INFORMATION GetExpParam(EXCEPTION_POINTERS* exception_pointers)
{
MINIDUMP_EXCEPTION_INFORMATION exp_param;
exp_param.ThreadId = GetCurrentThreadId();
exp_param.ExceptionPointers = exception_pointers;
exp_param.ClientPointers = TRUE;
return exp_param;
}

int GenerateDump(EXCEPTION_POINTERS* exception_pointers)
{
std::string dump_file_name = GetDumpFileName();

// The "\dump" whole directory
std::string dump_file_dir = GetDirectory(dump_file_name);

CreateDirectory(dump_file_dir.c_str(), NULL);

HANDLE dump_file_handle = CreateFile(dump_file_name.c_str(),
GENERIC_READ| GENERIC_WRITE, FILE_SHARE_WRITE | FILE_SHARE_READ,
0, CREATE_ALWAYS, 0, 0);

MINIDUMP_EXCEPTION_INFORMATION exp_param =
GetExpParam(exception_pointers);

MiniDumpWriteDump(GetCurrentProcess(), GetCurrentProcessId(),
dump_file_handle, MiniDumpNormal, &exp_param, NULL, NULL);

return 0;
}

LONG _stdcall GolbalExceptionHandler(EXCEPTION_POINTERS* exception_pointers)
{
GenerateDump(exception_pointers);
return EXCEPTION_EXECUTE_HANDLER;
}

void IntiializeMemory()
{
app_name = new std::string();
app_version = new std::string();
}

void MiniDumpBegin(const char* app_name, const char* app_version)
{
IntiializeMemory();

*minidump::app_name = app_name;
*minidump::app_version = app_version;

SetUnhandledExceptionFilter(GolbalExceptionHandler);
}
}

使用方法，在main函数开始出，调用：MiniDumpBegin函数，如图：

2. 使用注册表：

opendump.bat文件:----写注册表

@echo off
echo 正在启用Dump...
reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Windows Error Reporting\LocalDumps"
reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Windows Error Reporting\LocalDumps" /v DumpFolder /t REG_EXPAND_SZ /d "C:\CrashDump" /f
reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Windows Error Reporting\LocalDumps" /v DumpType /t REG_DWORD /d 2 /f
reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Windows Error Reporting\LocalDumps" /v DumpCount /t REG_DWORD /d 10 /f
echo Dump已经启用
pause
@echo on

closedump.bat　文件--- 删注册表

@echo off
echo 正在关闭Dump...
reg delete "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Windows Error Reporting\LocalDumps" /f
echo Dump已经关闭
pause
@echo on

使用方法：

1. 运行 opendump.bat文件
2. 去打开服务
