NServiceBus日志到自定义日志

Question

我注意到，当我在/install上调用NServiceBus.host.exe标志时，将在Application日志下创建一个事件日志源。问题是，我们已经将NServiceBus L4N配置为将事件写入相同的源，但使用自定义事件日志。

这会导致一个问题，因为如果我们在自定义事件日志下创建源，安装就会失败(NserviceBus安装程序抛出一个System.ArgumentException:源blah已经存在于本地计算机上)。

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呢？

我们使用的是NServiceBus 3.0.1.0

谢谢

Answer 1

只有在将Log4net配置为与端点名称相同的事件源名称时，才会出现此问题。

因此，我们可以在事件日志中使用不同的源名(在我们的例子中是<endpoint-name>.l4n)。就目前而言，这将解决这一问题。

如果事情确实是梨形的，您可以在注册表中找到事件日志源。

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

在那里，您可以手动删除不再需要的事件日志源。
