The lowest level (severity) that messages are logged at. For example, if Level is set to SourceLevels.Information then only messages at Information level and above will be logged (that is, messages at levels Information, Warning, Error, Critical). The default value is SourceLevels.All, which causes messages at all levels to be logged.

public SourceLevels Level { get; set; }
