logging

问题 I have a logger with two appenders (one Screen and other File). I want to have a Screen appender with a variable log level that can be changed and File appender that will log everything no matter what. So for instance, you can disable any output to screen (Screen appender) but get full logging to the level of TRACE in your logfile (File appender). I succeeded in getting changing Screen appender but I can't set File appender for the same logger to the level of TRACE. I tried using different

问题 What is the purpose of Serilog's @ syntax? If I run the following: var dummy = new { Foo = "Bar", Date = DateTime.Now }; Log.Information("Dummy object: {Dummy}", dummy); Then I get an output to the console like so: Time: 16:20 [Level: Information] (ManagedThreadID: 8) Message: Dummy object: "Foo = Bar, Date = 25/06/2016 16:20:30 }" If I change the {Dummy} to {@Dummy} then I get the same output Time: 16:22 [Level: Information] (ManagedThreadID: 8) Message: Dummy object: Foo: "Bar", Date: 06/25

问题 I am using slf4j+logback for logging in our application. Earlier we were using jcl+log4j and moved recently. Due to the high amount of logging in our application, there is a chance of disk being full in production environment. In such cases we need to stop logging and application should work fine. What I found from the web is that we need to poll logback StatusManager for such errors. But this will add a dependency with logback for the application. For log4j, I found that we can create an

问题 I'm using the built in logging provider for logging into the console ( Microsoft.Extensions.Logging.Console ) in a .NET Core console application. Each logging entry produces two lines in the output. I would like to have each entry in one single line. Is there a way to customize the output format? Here is an example how I use it: static void Main(string[] args) { var serviceProvider = new ServiceCollection() .AddLogging() // This adds the Microsoft logging. .AddSingleton
