serilog

问题 followed the Serilog Elasticsearch tutorial here: https://github.com/serilog/serilog-sinks-elasticsearch#handling-errors And nothing is working. I've seen other related SO posts that have suggestions + accepted answers but nothing is working. No errors, the console and file sinks work, however ES never gets written to. Here is the code that I am using: using System; using Microsoft.AspNetCore; using Microsoft.AspNetCore.Hosting; using Serilog; using Serilog.Events; using Serilog.Formatting

问题 I'm trying to determine if it's possible to configure the column options for serilog sink mssqlserver in the appsettings.json file for an ASP.Net Core 3 project. besides not filling the custom columns, the database is also created in the standard way without these column, so I added them by hand. This could point to a configuration issue? The SQL to create the table CREATE TABLE [dbo].[logtable]( [Id] [int] IDENTITY(1,1) NOT NULL, [Message] [nvarchar](max) NULL, [MessageTemplate] [nvarchar]

问题 I am trying to specify this filter in the appsettings .json file .Filter.ByExcluding(Matching.FromSource("Microsoft.AspNetCore.Hosting.Internal.WebHost")) The above syntax works when specified in c# But trying to specify the same in a json file does not work. "Filter": [ { "Name": "ByExcluding", "Args": { "expression": "Matching.FromSource = 'Microsoft.AspNetCore.Hosting.Internal.WebHost'" } } 回答1: You need to use Serilog.Filters.Expressions for this: Install-Package Serilog.Filters

问题 We use Simple Injector in ASP.NET Core application. Recently we've decided to use Serilog for logging purposes. Configuration was done in Program.cs as stated in their documentation. Then, in order to make Simple Injector able to resolve ILoggerFactory I did something like this: public void Configure(IApplicationBuilder app, IHostingEnvironment env) { if (env.IsDevelopment()) { app.UseDeveloperExceptionPage(); } app.UseMvc(); // As per my understanding, we force SimpleInjector to use //

问题 I am logging events of all types to single Json file irrespective of LogLevel. Now I have a requirement to log some custom performance counters to a seperate Json file. How can this be done in Serilog. Should I create different Logger Instance and use that where ever I am going to Log the performance counters? Want to use this with LibLog 回答1: You can do this by first making sure the performance counter events are tagged with either a particular property value ( OpenMappedContext() in LibLog)

问题 UPDATE: This turned out to be a discrepancy that exists in Serilog (which I tunnel to), but does not exist in NLog, which treats a single argument as a verbatim string (as one (and specifically, I) might expect) Using NLog, if I want to log something potentially containing embedded double braces: {{ without having them collapsed, what's the most efficient way? e.g.: NLog.LogManager.GetLogger("x").Warn("{{\"aaa}}") emits in my custom serilog-target: {"aaa} And I want: {{"aaa}} Is NLog

问题 I have two loggers with Serilog and they save to different files. I want to create the loggers through the appsettings.json as opposed to code. When I create my loggers through the Startup.cs configuration, I get a much more specific log and I prefer to have it that way as it's much clearer and will allow others to check the logs and understand what's going on without needing much technical knowledge. However, I want to apply this to the appsettings so that I can migrate the code to any other

问题 Each method in Azure Functions can have a Microsoft.Extensions.Logging.ILogger injected into it for logging. Using WebJobsStartup with a startup class you can change the logging to use Serilog using the following syntax: [assembly: WebJobsStartup(typeof(Startup))] namespace MyFuncApp { public class Startup : IWebJobsStartup { public void Configure(IWebJobsBuilder builder) { builder.Services.AddLogging( lb => lb.ClearProviders() .AddSerilog( new LoggerConfiguration() .Enrich.FromLogContext()
