I have a .NET Core 3.0 console application. I have a Microsoft.Extensions.Logging logger and I'm building Microsoft.Extensions.Configuration using a command line arguments.
My question is "How can I set the log levels via command line arguments?"
As pointed out in the Configuration in ASP.NET Core docs the arguments can be passed in one of the following ways:
No prefix CommandLineKey1=value1
Two dashes --CommandLineKey2=value2, --CommandLineKey2 value2
Slash (/) /CommandLineKey3=value3, /CommandLineKey3 value3
Example:
# Setting Warning level for all microsoft types
dotnet your.dll --Logging:LogLevel:Microsoft=Warning
# or setting Information level for your own types
dotnet run /Logging:LogLevel:YourNamespace:YourType Information
