How can I implement iLoggerFactory on my server IIS? - iis

Question

I implement iLoggerFactory on my .Net Core API , step :
creation of my folder 'logs'
implementation of the log in my 'logs' folder ( in startup.ts )
public void Configure(IApplicationBuilder app, IHostingEnvironment env,ILoggerFactory loggerFactory)
{
// log implementation
loggerFactory.AddConsole(Configuration.GetSection("Logging"));
loggerFactory.AddDebug();
loggerFactory.AddEventSourceLogger();
loggerFactory.AddFile("logs/app-{Date}.txt");
app.UseStaticFiles();
app.UseCors("AnyOrigin");
app.UseSwagger();
app.UseSwaggerUI(c =>
{
c.SwaggerEndpoint("/swagger/v1/swagger.json", "WebToolAPI");
c.RoutePrefix = string.Empty;
});
app.UseMvc();
}
And I create some log in controller who look like this :
_log.LogError("\r\n -- \r\n Datetime : {0} \r\n ERROR : id'" + id + "' not found \r\n --", DateTime.Now);
When I test it my local machine it's work but when I put my code in my IIS server it doesn't work. It doesn't create logs in my logs folder.

I resolve the issue.
In Startup.cs :
public class Startup
{
string LogFilePath;
public Startup(IHostingEnvironment env)
{
// location of the logs
var exePath = Assembly.GetEntryAssembly().Location.ToString();
var directoryPath = Path.GetDirectoryName(exePath);
LogFilePath = Path.Combine(directoryPath + "\\logs\\"); // you can replace "logs" by an other folder name
}
public void Configure(IApplicationBuilder app, IHostingEnvironment env,ILoggerFactory loggerFactory)
{
loggerFactory.AddDebug();
loggerFactory.AddFile(LogFilePath + "api-{Date}.txt",LogLevel.Debug,null,false,null,30); // you can replace "api" by an other file name for your log
}
}
In Program.cs :
public class Program
{
public static void Main(string[] args)
{
CreateWebHostBuilder(args).Build().Run();
}
public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>
WebHost.CreateDefaultBuilder(args)
.UseKestrel()
.UseIISIntegration()
.UseContentRoot(Directory.GetCurrentDirectory())
.UseStartup<Startup>();
}
