问题 We have a .Net web application and we were already logging to csv file. We just started logging with Elastic search.

I can only see http details in Kibana for each log. Can you let me know what could be the issue. Configuration looks like <target name="elastic" xsi:type="BufferingWrapper"

ASP.NET Core ---日志

阅读更多关于 ASP.NET Core ---日志

一、日志记录： 1、日志的作用：程序中记录日志一般有两个目的，故障定位和显示程序运行状态。好的日志记录方式可以提供足够多定位问题的依据。 2、日志的等级：有良好工作习惯的人，工作的时候会将领导交待下来的工作分为：紧急重要、重要不紧急、紧急不重要、不紧急不重要等；同样 ASP.NET Core 定义了以下日志级别（按严重性从低到高排列）。每次写入日志时都需指定其 LogLevel。日志级别指示严重性或重要程度。例如，如果方法正常结束则写入 Information 日志，如果方法返回 404 返回代码则写入 Warning 日志，如果捕获未知异常则写入 Error 日志。可以使用日志级别控制写入到特定存储介质或显示窗口的日志输出量。例如在生产中，可将所有 Information 及以下级别的日志放在卷数据存储，将所有 Warning 及以上级别的日志放在值数据存储。在开发期间，通常要将严重性为 Warning 或以上级别的日志发送到控制台。需要进行故障排除时，可添加 Debug 级别。 Trace = 0 表示仅对于开发人员调试问题有价值的信息。这些消息可能包含敏感应用程序数据，因此不得在生产环境中启用它们。默认情况下禁用。示例：Credentials: {"User":"someuser", "Password":"P@ssword"} Debug = 1

NLog and Unit Testing

阅读更多关于 NLog and Unit Testing

问题 I am using NLog for my logger. Everything works fine when logging when I run an .exe, or even debug through Visual Studio, NLog will still write to the file. But, if I run an object that calls the logger through a Unit test, the file is created but it is empty. Is there an extra setting/rule I need to add to the config to have NLog write to files under unit tests? I could mock NLog for this and not have log dumps, but I'd like to see if I can get this to work before I decide to just mock NLog

Where to configure NLog NHibernate bridge for logging sql configuration?

阅读更多关于 Where to configure NLog NHibernate bridge for logging sql configuration?

问题 As a proof-of-concept I am using a console application wrapping a proxy of a WCF service. I execute a few calls through the proxy and write the results to the console. Underlying the WCF service is a Data Access Layer built on the Repository pattern using NHibernate as an ORM. I want to write the NHib-generated SQL to the console. I have attempted to configure NLog using the NuGet package and guidance from here with no luck, but I suspect perhaps I don't properly understand where I need to

How to wrap each function in project?

阅读更多关于 How to wrap each function in project?

问题 I have tons of functions in my WinForms project and i'm using NLog for logging. I want to have an ability to wrap each function with nlogger.Info("start") and nlogger.Info("end") so i will know in which place actual exception occurred or where the code currently runs. Is there a smart way to do it or i will need to place lines from above in all of my functions ? 回答1: I believe that PostSharp can do this for you, and can apply at the assembly level (via assembly-level attributes). However, I
