!threads //show manage and unmanaged threads
!threadpool // show cpu usage and thread pool statistics
!runaway //show running threads and their cpu consuming
!threads -special //show all threads including gc, finalizer etc.
----------------堆栈查看----------------------------
~*e!mk //show all threads stack
~*kb 2000 //Examine the native callstacks
~*e!clrstack //Examine the .net callstacks 所有线程调用堆栈
!dso //find the objects on the stack
!clrstack 当前线程托管方法调用堆栈
k查看调用堆栈
!finalizequeue
!gcroot <address of string> 被根化（rooted）到哪里（即为什么它们不会被回收)
!eeHeap -gc查看.net GC 堆的大小
kb 2000产看当前线程本地（原生）调用堆栈
~* kb 2000 得到所有查看本地资源的callstack 触发GC的函数（mscorwks!)SVR::GCHeap::GarbageCollectGeneration）
GC 线程gc_heap::gc_thread_stub等待GC完成（GCHeap::WaitUntilGCComplete

------------------服务器上dump文件的方法-----
1.服务器上使用windows任务管理器，选择进程创建转储文件即可。
2.Debugging Tools for Windows里提供了一个好工具, 其路径与Debugging Tools for Windows的安装路径相同，使用的方法如下所示: 在命令行模式下进入工具所在目录执行： adplus.exe -hang -p 1234 -o d:dump
-p需要抓取文件的进程ID
-o文件输出的路径
adplus.exe -hang -p 33668 -o d:dump
adplus.exe -crash -p 33668 -o d:dump
当前安装包名称：X64 Debuggers And Tools-x64_en-us.msi
