Question

我注意到当我在NServiceBus.host.exe上调用/ install标志时，会在Application事件日志下创建一个事件日志源。问题是，我们已将NServiceBus L4N配置为将事件写入同一源但在自定义事件日志下。

这会导致问题，因为如果我们在自定义事件日志下创建源，则安装失败（NserviceBus安装程序抛出System.ArgumentException：本地计算机上已存在Source blah）。

那么我们如何阻止NServiceBus安装程序尝试在应用程序事件日志下创建事件源？

我们正在使用NServiceBus 3.0.1.0

Answer 1

如果我们使用与端点名称相同的事件源名称配置Log4net，则只会出现此问题。

因此我们可以在事件日志中使用不同的源名称（在我们的例子中为<endpoint-name>.l4n）。这将解决现在的问题。

Answer 2

如果事情变得非常梨形，您可以在注册表中找到事件日志源

HKLM/SYSTEM/ControlSet001/services/eventlog/...

从那里，您可以手动删除不再需要的事件日志源。

NServiceBus记录到自定义日志
