kandi X-RAY | serilog Summary

serilog is a C# library typically used in Logging applications. serilog has no bugs, it has no vulnerabilities, it has a Permissive License and it has medium support. You can download it from GitHub.

Serilog is a diagnostic logging library for .NET applications. It is easy to set up, has a clean API, and runs on all recent .NET platforms. While it's useful even in the simplest applications, Serilog's support for structured logging shines when instrumenting complex, distributed, and asynchronous applications and systems. Like many other libraries for .NET, Serilog provides diagnostic logging to files, the console, and many other outputs. Unlike other logging libraries, Serilog is built from the ground up to record structured event data. Serilog uses message templates, a simple DSL that extends .NET format strings with named as well as positional parameters. Instead of formatting events immediately into text, Serilog captures the values associated with each named parameter. The example above records two properties, Position and Elapsed, in the log event. The @ operator in front of Position tells Serilog to serialize the object passed in, rather than convert it using ToString(). Serilog's deep and rich support for structured event data opens up a huge range of diagnostic possibilities not available when using traditional loggers.

            Use serilog as logging provider in blazor webassembly client app
            Asked 2022-Mar-31 at 10:10

            I'd like to use serilog in a blazor webassembly net 6 app, both on client and server sides. In this article I found out how to relay log entries to server so that they are written in log files.

            In this approach however the Log static class is used to explicitly add log entries.

            I'd like to add serilog as logging provider so that exceptions and automatically generated information are logged, too.

            I can't see Serilog messages after service is run up
            Asked 2022-Mar-20 at 08:54

            I try to learn Serilog in practice on a Web App. I can't see the messages after it is run up. When I debug, I'm in successfully OnGet() method and trigger the exception. However, both information and error messages aren't shown. I get only --> App is starting up .... message, which is defined in the Program.cs

            I expect to see count numbers and the error message as output. What point do I miss? Doesn't it read the appsettings.json? If it is not read, it shouldn't override Microsoft's messages, but it overrides.

            AspNet Core Serilog SQL custom column not working
            Asked 2022-Mar-08 at 17:09

            I've setup SeriLog in my ASP.NET Core MVC Web App with dotnet 3.1, and added a couple of extra columns. Trying to populate UserName automatically does not work. All else works fine. I'm using the Microsoft.Extensions.Logging ILogger to inject my logger in the controllers. Can't this property be automatically set using the LogContext, or do I have to explicitly call the object for each log entry like so, ("Info logged by {UserName}", User.Identity.Name).

            Here's my Program.cs



            Answered 2022-Mar-08 at 17:09

            You can use UseSerilogRequestLogging like below to add custom properties like Username and IPAddress. You should add it after UseAuthentication to get logged in Username.

            You don't have to use another ILogger to inject separately. Serilog handles it by itself. Just use sub-loggers and add some WriteTo.Logger . Then you can use ILogger somewhere inside your code and it automatically saves logs according to your configuration.

            Custom Serilog sink with injection?

            Answered 2022-Feb-23 at 18:28

            If you refer to the Provided Sinks list and examine the source code for some of them, you'll notice that the pattern is usually:

            1. Construct the sink configuration (usually taking values from IConfiguration, inline or a combination of both)
            2. Pass the configuration to the sink registration.

            Then the sink implementation instantiates the required services to push logs to.

            An alternate approach I could suggest is registering Serilog without any arguments (UseSerilog()) and then configure the static Serilog.Log class using the built IServiceProvider:

            Add try/catch similar to the above around IHostBulder.Build() in any .NET/EF Core 6.0 RC2 project, and attempt to add a migration can reproduce the issue.

            Why do I get Serilog SelfLog error while using Serilog logging?
            Asked 2022-Feb-25 at 06:57

            I have an interesting error while using Serilog SelfLog. The error is:



            Answered 2022-Feb-23 at 10:18

            As alluded to in the comment from @Daniel A. White, you are doing a risky thing -- trying to write to a file, in a handler that's provided on an "if all else fails" basis. Some examples:

            • if the disk is full and the File Logger can't write (File sinks dont necessarily do that, but if they wanted to communicate failure, it would be via the SelfLog)
            • if a message string is malformed (Serilog logging calls will never throw; this is based on a fundamental tenet in the wiki about the logging not being important enough to stop a working app from working)

            While the Serilog debugging and diagnostics Wiki page currently shows an example of writing to a file, that's simply not the nature of the contract -- it must not fail.

            Hence, if you actually want to emit the SelfLog to a file, you will need to add a try/catch and swallow the exception in the handler.

            I would say its pretty questionable value to have a file as a backup when the File Sink is your primary output. This is doubly the case as you don't have any mechanism to ensure it gets trimmed (imagine you had a tight loop logging with a malformed message string - it would fill your disk eventually).

            I personally have handled this tradeoff by echoing the SelfLog to my Console Sink (which logging won't throw, per the above) on the basis that the operating environment (think Kubernetes) can be trusted to capture it, or alert.



            How to perform logging in ConfigureServices method of Startup.cs in ASP.NET Core 5.0
            Asked 2022-Feb-12 at 09:53

            Constructor injection of a logger into Startup works in earlier versions of ASP.NET Core because a separate DI container is created for the Web Host. As of now only one container is created for Generic Host, see the breaking change announcement.




            Answered 2021-Oct-05 at 16:00

            If you are using NLog the easiest way to log in you startup.cs is to add private property.



            .Net 6.0 Configuration files
            Asked 2022-Jan-13 at 21:22

            Been getting a app that serves up data to a VBA application. Now at point trying to get configuration files (appsettings.json & appsettings.Development.Json). Right now it's a .net6.0 console app, later I'm making it an IconTrayApp.

            Ran into a problem, the main Program.cs method gets the appsettings.json and the worker gets the appssettings.Developement.json. I understand why Main() get the none environment json, because I explicitly load it. But I want the app to use the same file both in an out of the IDE.

            here is program.cs



            Answered 2022-Jan-13 at 21:22

            Your main app(Primary app- 1st) uses any appsettings.json and you need to use the same file in the called console app(Secondary app - 2nd).

            You can call the 2nd with args

            1. The settings file from de primary program
            Located for example in "C:\appsettings.json"



            MS Logger factory and Serilog issue getting log messages to file
            Asked 2022-Jan-10 at 23:53

            I've been building a tool to resolve some data related issues. Bottom line this is in .Net 5.0 with future to port to .net 6.0.

            I've used Serilog in the past without issues. But as part of my "tool" I need to use a TCP Server. I've selected to use WastonTCP as it simply works.

            The problem is that it uses the MS Logger factory and defaults output to Console. Not a production desired result.

            When I run the app now I get the start and stop messages in the log but none of these show below

            These messages I want in the serilog. Here is the program.cs code:



            Answered 2022-Jan-10 at 23:53

            When you do Log.Logger = loggerConfig.CreateLogger(); you are configuring the global static Serilog.Log object. It will work as long as you call it via Log.Write() etc.

            Your problem starts from the fact that, in your worker, I'm guessing you're using an injected ILogger<>. This will inject an MS ILogger. Unfortunately you have not told the MS ILogger to use serilog.

            Linking the two should be straightforward (as per the instructions); you just tell the host builder you want to use Serilog:

            Install serilog

            Serilog is installed from NuGet. To view log events, one or more sinks need to be installed as well, here we'll use the pretty-printing console sink, and a rolling file set:. The simplest way to set up Serilog is using the static Log class. A LoggerConfiguration is used to create and assign the default logger.
