Using RestrictedToMinimumLevel to Override the Default Minimum Level in Serilog - serilog

Question

I have configured Serilog to have a default MinimumLevel of Verbose.
But I want to confine the logging to SQL Server to Warning (and up).
My config (in JSON) looks like this:
{
"Serilog": {
"Using": [ "Serilog.Sinks.Console", "Serilog.Sinks.File", "Serilog.Sinks.MSSqlServer", "My.Framework.AspNet" ],
"Enrich": [ "FromLogContext", "WithEventType" ],
"MinimumLevel": {
"Default": "Verbose"
},
"WriteTo": [
{
"Name": "MSSqlServer",
"restrictedToMinimumLevel": "Warning",
"Args": {
"connectionString": "Server=yada yada yada ;MultipleActiveResultSets=True",
"tableName": "ErrorLogs",
"autoCreateSqlTable": false,
"columnOptionsSection": {
"disableTriggers": true,
"clusteredColumnstoreIndex": false,
"primaryKeyColumnName": "Id",
"addStandardColumns": [ "LogEvent" ],
"removeStandardColumns": [ "Properties" ],
"additionalColumns": [
{
"ColumnName": "EventType",
"DataType": "bigint",
"AllowNull": true
}
],
"id": {
"columnName": "Id",
"nonClusteredIndex": true
},
"eventType": {
"columnName": "EventType"
},
"message": {
"columnName": "Message"
},
"messageTemplate": {
"columnName": "MessageTemplate"
},
"level": {
"columnName": "Level",
"storeAsEnum": false
},
"timeStamp": {
"columnName": "TimeStamp",
"convertToUtc": true
},
"exception": {
"columnName": "Exception"
},
"logEvent": {
"columnName": "LogEvent"
}
}
}
}
],
"Properties": {
"Application": "App API"
}
}
}
Upon inspecting my logs, I'm seeing everything from Verbose up.
Is there something I'm doing wrong with the restrictedToMinimumLevel property?
I also tried placing it inside the Args property, with no luck.
Cheers

Answer 1

I haven't tried it but upon this GitHub issue I think restrictedToMinimumLevel should be in Args. So change your WriteTo configuration like this:
"WriteTo": [
{
"Name": "MSSqlServer",
"Args": {
"restrictedToMinimumLevel": "Warning",
"connectionString": "Server=yada yada yada ;MultipleActiveResultSets=True",
"tableName": "ErrorLogs",
"autoCreateSqlTable": false,
"columnOptionsSection": {
"disableTriggers": true,
"clusteredColumnstoreIndex": false,
"primaryKeyColumnName": "Id",
"addStandardColumns": [ "LogEvent" ],
"removeStandardColumns": [ "Properties" ],
"additionalColumns": [
{
"ColumnName": "EventType",
"DataType": "bigint",
"AllowNull": true
}
],
"id": {
"columnName": "Id",
"nonClusteredIndex": true
},
"eventType": {
"columnName": "EventType"
},
"message": {
"columnName": "Message"
},
"messageTemplate": {
"columnName": "MessageTemplate"
},
"level": {
"columnName": "Level",
"storeAsEnum": false
},
"timeStamp": {
"columnName": "TimeStamp",
"convertToUtc": true
},
"exception": {
"columnName": "Exception"
},
"logEvent": {
"columnName": "LogEvent"
}
}
}
}
]

For the restrictedToMinimumLevel to work via configuration through appSettings.json, the restrictedToMinimumLevel must be inside the Args section as it's described in the documentation. There's nothing unique about the MsSQLServer sink that would require the configuration to be any different.
As you can see, only events with log level >= Warning are stored in the SQL Server table:
Program.cs
using System;
using System.IO;
using Microsoft.Extensions.Configuration;
using Serilog;
using Serilog.Debugging;
namespace ReproSerilogSO66019586
{
class Program
{
static void Main(string[] args)
{
SelfLog.Enable(msg => Console.WriteLine("ERROR: {0}", msg));
var configuration = new ConfigurationBuilder()
.SetBasePath(Directory.GetCurrentDirectory())
.AddJsonFile("appsettings.json")
.Build();
Log.Logger = new LoggerConfiguration()
.ReadFrom.Configuration(configuration)
.WriteTo.Console()
.CreateLogger();
Log.Verbose("This is Verbose!");
Log.Debug("This is Debug!");
Log.Information("This is Information!");
Log.Warning("This is Warning!");
Log.Error("This is Error!");
Log.Fatal("This is Fatal!");
Log.CloseAndFlush();
Console.ReadLine();
}
}
}
appSettings.json
{
"Serilog": {
"Using": [ "Serilog.Sinks.Console", "Serilog.Sinks.File", "Serilog.Sinks.MSSqlServer" ],
"Enrich": [ "FromLogContext" ],

},
"WriteTo": [
