Merhabalar,

Gecen gun yaptigimiz mobil projeyi yayina aldik.

40 user ile API server'in ram kullanimi %90 lara cikti. Ram artiyor surekli ve bosalmiyor. Monitor edip restart ediyorum cozum bulana kadar fakat bir cozum bulamadim 2 gundur uyumadim birseyi gozden kaciriyorum yardimci olursaniz cok sevinirim.

Hardware: 4 GB Memory / 80 GB Disk / 2 CPU - CentOS 7.4 x64

Software: c# dot net core 2.0.8 & mongo 3.6.2 visual studio communtiy for mac ile gelistirildi.

Server: Nginx (proxy server)

Nginx configinde birsey atlamis olabilirim conf dosyasinda bir hata var mi sizce? API buludungu configuration location /app

Kestrel garbage collectorun calismadigindan supheleniyorum. Daha once kestrel ile is yapmadim fakat bu web server saniyede 1.2m istege yanit verebiliyor benchmark testlerindeki bilgiye gore.

GarbageCollection'un enabled olmadigini dusundum runtimeconfiguration.json olusturup GC.Server = true; ile api'yi baslattim hic bir sey degismedi.

ApplicationInsights development icin data topladigini buldum disable etmek icin startup.cs ye

TelemetryConfiguration.Active.DisableTelemetry = true; ekledim yine birsey degismedi ram artmaya devam ediyor.

Startup.cs'de service sinifinlarini ioc ye singleton olarak ekliyorum. Ilk yayina cikarken AddTransient kullanmistim AddSingleton'a cevirdim birsey degismedi.

services.AddSingleton<IMessageCollection, MessageCollection>();

ApiController constructoruna serviceleri new keywordu olmadan olusturuyorum.

[Authorize, Route("api/[controller]")] public class MessageController : Controller { readonly IMessageCollection _messageCollection; readonly IConfiguration _config; public MessageController(IMessageCollection messageCollection, IConfiguration config) { _messageCollection = messageCollection; _config = config; } }

Context repository pattern'inde bir sorun olabilir mi :

public class MongoContext {

public IMongoDatabase _database = null;

public MongoContext()

{

if (_database == null)

{

Console.WriteLine("database null connect mongo");

var client = new MongoClient($"{protocol}://{username}:{password}@{host}:{port}?authSource=admin");

if (client != null)

{

_database = client.GetDatabase(database);

}

else

{

throw new Exception("Mongo client can not be null. Check your connection string.");

}

}

}

public IMongoCollection<Message> Messages => _database.GetCollection<Message>("user");

}

public interface IMessageCollection {

Task<Message> GetByIdAsync(string id);

Task<Message> SaveAsync(Message entity);

Task DeleteAsync(string id);

Task<ICollection<Message>> FindAllAsync(Expression<Func<Message, bool>> predicate);

Task<Message> FindAsync(Expression<Func<Message, bool>> predicate);

Task<ICollection<Message>> PagingAsync(Expression<Func<Message, bool>> predicate, int offset, int limit);

Task<long> CountAsync(Expression<Func<Message, bool>> predicate);

}

public class MessageCollection : IMessageCollection {

readonly MongoContext _context = null;

public MessageCollection(){

_context = new MongoContext();

}

public virtual async Task<Message> GetByIdAsync(string id) {

return await _context.Messages.Find(x => x.Id.Equals(id)).FirstOrDefaultAsync();

}

}
