Serliog Sinks: Reading from json configuration not working - asp.net

Question

The system is not autocreating logs table and logging errors in my postgres database. I am using Serilog.Sinks.PostgresSQL. What am I missing?
Program.cs:
public class Program
{
public static void Main(string[] args)
{
var path = Directory.GetCurrentDirectory();
var environmentName =Environment.GetEnvironmentVariable("ASPNETCORE_ENVIRONMENT") ?? "Production";
var configuration = new ConfigurationBuilder()
.SetBasePath(path)
.AddJsonFile("appsettings.json", optional: false, reloadOnChange: true)
.AddJsonFile($"appsettings.{environmentName}.json", optional: true, reloadOnChange: true)
.AddEnvironmentVariables()
.Build();
Log.Logger = new LoggerConfiguration()
.Enrich.FromLogContext()
.ReadFrom.Configuration(configuration)
.CreateLogger();
try
{
var iWebHost = CreateWebHostBuilder(args).Build();
iWebHost.Run();
}
finally
{
Log.CloseAndFlush();
}
}
public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>
WebHost.CreateDefaultBuilder(args)
.UseStartup<Startup>()
.UseSerilog();
}
appsettings.Development.json
"Serilog": {
"Using": [ "Serilog.Sinks.PostgreSQL" ],
"MinimumLevel": "Warning",
"WriteTo": [
{
"Name": "PostgreSQL",
"Args": {
"connectionString": "Server=localhost;Port=5432;Database=postgres;User Id=postgres;Password=<password>;Pooling=true;Minimum Pool Size=1;Maximum Pool Size=100;",
"tableName": "Logs",
"autoCreateSqlTable": true,
"batchPostingLimit": 1
}
}
]
}

Answer 1

Your problem seems that the parameter name of the auto-generated table is incorrect. Try to change the parameter like below :
"Serilog": {
"Using": [ "Serilog.Sinks.PostgreSQL" ],
"MinimumLevel": "Warning",
"WriteTo": [
{
"Name": "PostgreSQL",
"Args": {
"connectionString": "Server=localhost;Port=5432;Database=postgres;User Id=postgres;Password=<password>;Pooling=true;Minimum Pool Size=1;Maximum Pool Size=100;",
"tableName": "Logs",
"needAutoCreateTable": true,
"batchPostingLimit": 1
}
}
]
}

Updated :
You could add Serilog.Debugging.SelfLog.Enable in the Configure method to get the exceptions generated by Serilog itself , refer to below code :
Serilog.Debugging.SelfLog.Enable(msg =>
{
Debug.Print(msg);
Debugger.Break();
});
Here is the my working demo ,if you still have the error ,you could check the difference with yours .

Try it like this:
WebHost.CreateDefaultBuilder(args)
.UseStartup<Startup>()
.UseSerilog((hostingContext, loggerConfiguration) => loggerConfiguration
.ReadFrom.Configuration(hostingContext.Configuration))
.Build();

I was looking for this too and found out on the project's github issue page
You need to use the "removeStandardColumns" property inside "columnOptionsSection".
WriteTo": [
{
"Name": "PostgreSQL",
"Args": {
"connectionString": "User ID=;Password=;Host=localhost;Port=5432;Database=",
"needAutoCreateTable": "true",
"schemaName": "banklink",
"tableName": "Logs",
"columnOptionsSection": {
"removeStandardColumns": [
"Message",
"Message_Tempate",
"Level",
"Timestamp",
"Exception",
"Log_Event"
],
"customColumns": [
{
"ColumnName": "message",
"DataType": "text",
"AllowNull": true
},
{
"ColumnName": "message_template",
"DataType": "text",
"AllowNull": true
},
{
"ColumnName": "logcode",
"DataType": "integer",
"AllowNull": true
},
{
"ColumnName": "level",
"DataType": "integer",
"AllowNull": true
},
{
"ColumnName": "timestamp",
"DataType": "timestamp",
"AllowNull": true
},
}
}
}
}
