Log levels for logging in ASP.NET Core

In ASP.NET Core, you can use the Microsoft.Extensions.Logging NuGet package to write logs to a number of logging providers with ILogger.

Within ILogger, there are a number of log levels that can be written as part of a log. These include:

• Warning
• Error
• Critical
• Debug
• Trace
• Information

Can you order these log levels in-order of severity level? Start with 0 being the least severe, and go up to 5 which will be the most severe.
