serilog

问题 As a step in switching from NLog to Serilog, I want to redirect the standard wiring underlying standard invocations of NLog's LogManager.GetLogger(name) to Bridge any code logging to NLog to forward immediately to the ambient Serilog Log.Logger - i.e. I want to just one piece of config that simply forwards the message, without buffering as Log4net.Appender.Serilog does for Log4net. Can anyone concoct or point me to a canonical snippet that does this correctly and efficiently please?

问题 I created a new .NET Core web project using Visual Studio and integrated Serilog. It reads settings from the appsettings.json (via .UseSerilog((ctx, config) => { config.ReadFrom.Configuration(ctx.Configuration); }) ). In the appsettings.json, the path to write the log is specified at Serilog/WriteTo/Args/pathFormat . If I set that value to log.txt , it will attempt to write the file to `c:\program files\iisexpress\log.txt'. How can I get it to write to the content root of my web app? 回答1:

问题 In the WriteTo.Observer method I want to pass the formatted log message as it is rendered using the formatting template. How might I accomplish that? Thanks class Program { static void Main(string[] args) { Log.Logger = new LoggerConfiguration() .MinimumLevel.Information() .WriteTo.LiterateConsole() .WriteTo.RollingFile("log-{Date}.txt") .WriteTo.Observers(events => events.Do(evt => { Console.WriteLine($"Observed event {evt.MessageTemplate.Text}"); }).Subscribe()) .WriteTo.Observers(events =>

问题 This question is related to Steven’s answer - here. He proposed a very good logger wrapper. I will paste his code below: public interface ILogger { void Log(LogEntry entry); } public static class LoggerExtensions { public static void Log(this ILogger logger, string message) { logger.Log(new LogEntry(LoggingEventType.Information, message, null)); } public static void Log(this ILogger logger, Exception exception) { logger.Log(new LogEntry(LoggingEventType.Error, exception.Message, exception));

问题 I have a .NET Core 2.0 application in which I successfully use Serilog for logging. Now, I would like to log some database performance statistics to a separate sink (they are not for debugging, which basically is the purpose of all other logging in the application, so I would like to keep them separate) and figured this could be accomplished by creating the DB statistics logger with Log.ForContext<MyClass>() . I do not know how I am supposed to configure Serilog using my appsettings.json to

问题 Is there a way to configure multiple Serilog RollingFiles through appSetting? I want to create separate log files for Information and Error levels. 回答1: Not directly - it's possible to use a setting prefix like: .ReadFrom.AppSettings() .ReadFrom.AppSettings(settingPrefix: "2") And then add the additional sink like: <add key="2:serilog:write-to:RollingFile.pathFormat" value="..." /> Baking this properly into the app settings configuration provider has been a "TODO" for a while. If configuring

问题 I am using Serilog - RollingFile Sink, but it stores all data in a single file for a day. In my application, 1 GB log is written in a day. So I want to roll log file on the basis of date and size. How can I configure RollingFile Sink to roll files based on date and size? 回答1: Nowadays Serilog.Sinks.RollingFile package is deprecated in favor of Serilog.Sinks.File (see the github project readme intro). Serilog.Sinks.File package has been upgraded to support file rolling. You can use the

问题 I am working on a .net core project which uses a nuget package say NUGET 1. The package references serilog for logging purpose. Everything works fine till here. The references of serilog can be seen in the image. As soon as I add another nuget package say NUGET 2. The project still builds but this time I get a runtime error below. Method not found: 'Serilog.LoggerConfiguration Serilog.LoggerConfigurationLogentriesExtensions.Logentries(Serilog.Configuration.LoggerSinkConfiguration, System

问题 I am able to use LoggerConfiguration() in my C# code with various Serilog Sinks but my compiler is complaining about the specification of my use of ".WriteTo.File". I am confused because I have ben able to use this specification in another demo solution. I wonder if there is some sort of Assembly I need to add as a reference. I have run "Install-Package Serilog.Sinks.File" from the "Package Manager Console" but that did not seem to have any effect or change. What directive am I missing or

问题 I can not find any resources for installing Serilog in an ASP.Net 4.7.1 WebApi project. Can someone help me out? There are a ton of .Net Core resources but that does not help. 回答1: Install required NuGet packeges, open the Package Manager Console and type Install-Package Serilog Install-Package Serilog.Sinks.File Create new static class with name logger that will have Serilog configuration public static class Logger { private static readonly ILogger _errorLogger; static Logger() {
