LogLevel at runtime #50035

Open ducalai opened 4 years ago

ducalai commented 4 years ago

We have a scenario where our application should get its logging LogLevel configuration using an API. Then, we would like to set it at runtime. I know Serilog supports it using LoggingLevelSwitch, but how to solve it directly in Microsoft.Extensions.Logging? If not possible now, are you planning to support it?

You can create / update the Configuration with the values from the mentioned API before building the host.

So, in Program.cs using .ConfigureLogging(this IWebHostBuilder hostBuilder, Action<WebHostBuilderContext, ILoggingBuilder> configureLogging) extension method? Once host is created, it is no more possible?

Logging monitors config for changes and reloads, so if your configuration source supports reloading (such as the built-in JSON one), then changing the file will automatically trigger a reload and reconfiguration of logging without requiring a restart of the app.

dynamic seting ILogger's LogLevel at runtime is very very useful @anurse

Issue Details
We have a scenario where our application should get its logging `LogLevel` configuration using an API. Then, we would like to set it at runtime. I know Serilog supports it using `LoggingLevelSwitch`, but how to solve it directly in Microsoft.Extensions.Logging? If not possible now, are you planning to support it?
