!ndiskd.nbllog

!ndiskd.nbllog 扩展显示系统上所有 NBL (NET_BUFFER_LIST) 活动的日志。

!ndiskd.nbllog [-stacks] 

参数

-栈
包括调用堆栈。

DLL

Ndiskd.dll

注解

重要提示 !ndiskd.nbllog 要求在调试对象目标计算机上启用 NBL 跟踪。 默认情况下,Windows 的所有配置中均未启用 NBL 跟踪。 如果未启用 NBL 跟踪,!ndiskd 将提供有关如何启用它的说明,如以下代码片段所示。

0: kd> !ndiskd.nbllog
    This command requires NBL tracking to be enabled on the debugee target
    machine.  (By default, client operating systems have level 1, and servers
    have level 0).  To enable, set this REG_DWORD value to a nonzero value on
    the target machine and reboot the target machine:
    
    HKLM\SYSTEM\CurrentControlSet\Services\NDIS\Parameters ! TrackNblOwner
    Possible Values (features are cumulative)
    * 0:  Disable all tracking.
    * 1:  Track the most recent owner of each NBL (enables !ndiskd.pendingnbls)
    * 2:  Scan for leaks at runtime (use with StuckNblReaction)
    * 3:  Keep a full history of all activity (enables !ndiskd.nbl -log)
    * 4:  Take stack capture snapshots (enables !ndiskd.nbl -log -stacks)
    This command requires level 3 or higher.

NBL 日志显示系统上的网络流量。 !ndiskd.netreport 分析 NBL 跟踪日志,以直观地显示此网络流量。 因此,如果未启用 NBL 跟踪,!ndiskd.netreport 将无法显示这些信息。

示例

在目标调试对象计算机上启用 NBL 跟踪后,输入 !ndiskd.nbllog,命令以查看系统上所有 NBL 流量的日志。 如以下示例所示,在没有参数的情况下运行运行 !ndiskd.nbllog 会将输出限制为 200 个事件,这可以通过使用 -force 选项重新运行命令来绕过。 为简洁起见,本例中已删除了输出的中间部分。
