Serilog HTTP sink + Logstash: Splitting Serilog message array into individual log events

≡放荡痞女 提交于 2019-12-05 15:41:09
We're using Serilog HTTP sink to send the messages to Logstash. But the HTTP message body is like this: { "events": [ { "Timestamp": "2016-11-03T00:09:11.4899425+01:00", "Level": "Debug", "MessageTemplate": "Logging {@Heartbeat} from {Computer}", "RenderedMessage": "Logging { UserName: \"Mike\", UserDomainName: \"Home\" } from \"Workstation\"", "Properties": { "Heartbeat": { "UserName": "Mike", "UserDomainName": "Home" }, "Computer": "Workstation" } }, { "Timestamp": "2016-11-03T00:09:12.4905685+01:00", "Level": "Debug", "MessageTemplate": "Logging {@Heartbeat} from {Computer}",

Exception destructuring in Serilog

╄→гoц情女王★ 提交于 2019-12-05 09:13:53
问题 Serilog has a convenient way of destructuring objects as shown in this example: logger.Debug(exception, "This is an {Exception} text", exception); logger.Debug(exception, "This is an {@Exception} structure", exception); The first line causes the logger to log an exception as plain text (by calling ToString()), and the second line causes the logger to write exception properties as separate fields. But what about this overload: logger.Debug(exception, "This is an exception", exception); This

How to output event source Class Name in serilog RollingFile outputTemplate?

孤者浪人 提交于 2019-12-05 01:20:15
The RollingFile.outputTemplate that I am using for my sink in <appSettings> configuration is as below: <add key="serilog:write-to:RollingFile.outputTemplate" value="{Timestamp:HH:mm:ss} [{Level}] {Message}{NewLine}{Exception}" /> The output log I am getting as: 19:55:10 [Information] Application_Start... However, I want to also output the Class Name (source) from where the Log was generated, like - 19:55:10 [Information] [Global.asax.cs] Application_Start... What should I add to the "value"? I added [Source] but is not working. value="{Timestamp:HH:mm:ss} [{Level}] [Source?] {Message}{NewLine}

Serilog RollingFile

醉酒当歌 提交于 2019-12-05 00:55:14
I am trying to use WriteTo.RollingFile with Serilog as the following: var log = new LoggerConfiguration().WriteTo.RollingFile( @"F:\logs\log-{Date}.txt", LogEventLevel.Debug).CreateLogger(); log.Information("this is a log test"); My understanding is that the log file will be created and named based on the date, and also it will write to a new file everyday, however I am getting a new log file for each log entry during the same day! How to configure Serilog to write to a new file every day so ideally I have a single log file per day? And is there any archiving process to delete files older than

Serilog in Windows-Service not writing to logfile

十年热恋 提交于 2019-12-04 22:50:27
I am using Serilog within an TopShelf Service, logging to the console and a rolling file. When running the service in a console my messages are written to the logfile, but when I install the service and run it no logging occurs. Is there anything special I need to configure? The file is written to the binaries folder under ".\logs\log-{date}.txt". Best regards Gope I had a very similar issue. In my case the problem was with relative paths. I just had to specify absolute path. Now it works like a charm. WriteTo.RollingFile(AppDomain.CurrentDomain.BaseDirectory + "\\logs\\log-{Date}.log") Hope

C# ASP.NET Core Serilog add class name and method to log

可紊 提交于 2019-12-04 12:56:52
问题 I recently added logging to my ASP.Net Core project. Currently the log writes to a .txt file in this format: {Timestamp:yyyy-MM-dd HH:mm:ss.fff zzz} [{Level}] {Message}{NewLine}{Exception} For example: 2017-11-30 13:58:22.229 +01:00 [Information] Item created in database. This is fine but I would like to have the name of the class that logs and the method that is being executed to this .txt file. For example when Class A writes something to the database using Method B and logs this, I would

Pattern to use Serilog (pass ILogger vs using static Serilog.Log)

跟風遠走 提交于 2019-12-03 01:20:22
Background In a new project where Serilog was chosen as the logger I automatically started passing around ILogger interface. The code accesses Log.Logger once and from then the classes that desire logging accept ILogger via constructor injection. I was challenged on this practice and the advice was to use the static methods on the Log class, e.g. Serilog.Log.Debug(...) . The argument is that there is a set; on Log.Logger so mocking is easy. Looking at the api I can see that one of the benefits of passing ILogger are the ForContext methods. I spent some time on the webs and in the Serilog 's

Redirect all NLog output to Serilog with a custom Target

你离开我真会死。 提交于 2019-12-01 21:23:38
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? Requirements I can think of: Maintain the level, i.e. nlog.Warn should be equivalent to serilog.Warning It's ok

Add user to the log context when using Serilog and Asp.Net Core

一世执手 提交于 2019-12-01 15:14:31
I'm trying to use Serilog together with my ASP.Net Core 1.0 project. I just can't seem to get the current logged in user added to properties logged. Has anyone figure this out yet? I have tried this: using System.Threading.Tasks; using Serilog.Context; using Microsoft.AspNetCore.Builder; using Microsoft.AspNetCore.Http; using System.Security.Claims; using xxx.Models; namespace xxx.Utils { public class EnrichSerilogContextMiddleware { private readonly RequestDelegate _next; public EnrichSerilogContextMiddleware(RequestDelegate next) { _next = next; } public async Task Invoke(HttpContext
