Try the following change in your code, set the category of the first AddFilter is null
public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>
WebHost.CreateDefaultBuilder(args)
.ConfigureAppConfiguration((hostingContext, config) =>
{
var env = hostingContext.HostingEnvironment;
config.AddEnvironmentVariables();
})
.ConfigureLogging((hostingContext, logging) =>
{
logging.AddConsole();
logging.AddFilter(null, LogLevel.Warning);
})
.UseStartup<Startup>()
.ConfigureLogging(logging => logging.AddFilter("Microsoft", LogLevel.Warning));
Add logWarning to test in Home/Index
private readonly ILogger _logger;
public IndexModel(ILogger<IndexModel> logger)
{
_logger = logger;
}
public void OnGet()
{
_logger.LogInformation("Log Information");
_logger.LogWarning("Log Warning");
}
The screenshot of result
Great code, very clear. It looks as though we can only suppress (filter) log items that would be created in our own code. I was hoping to prevent the informational log items that VS generates as my code runs. Warnings and worse, fine, but not all the others.
I am also struggling with the same thing. Can't get rid of those microsoft/system logs.
