OpenTSDB'de yığın talebi nedir?

Question

Bazı veri noktalarını, yığın HTTP isteklerini desteklemeyen bir OpenTSDB sunucusuna göndermek için Qt4 kullanıyorum.

kodu temelde şudur:

QNetworkRequest request(m_url); 
request.setHeader(QNetworkRequest::ContentTypeHeader, QString("application/json")); 
request.setHeader(QNetworkRequest::ContentLengthHeader, jsonRequest.toAscii().size()); 
m_networkAccessManager.post(request, jsonRequest.toAscii()); 

jsonRequest veri noktalarını ihtiva eden bir QString olup. Bu kod, sunucuya veri yüklemek için zaman zaman denir ve genellikle iyi çalışır. Ancak, bazen "Chunked isteğinin desteklenmediğini" belirten openTSDB'den bir hata alıyorum. Bu, istek biraz daha büyük olduğunda (ve daha büyük, veri KB'sini kastediyorum) gerçekleşmiş gibi görünüyor.

düzenleme: Ben sorunu doğar isteğin bir tcpdump yaptık ve aslında yığın halinde mutlaka görülmesi değildir:

Qt bir yığın halinde kullanmak değişiyordu düşünüyordum istek daha büyük olduğunda istek, ancak durum böyle değil. Şimdiki soru şudur: openTSDB'de yığınlanmış bir talep nedir?

Answer 1

Sonunda benim isteği yığın halinde düşündüğü Nedeni bulduktan: OpenTSDB içten ağ için netty kullanır ve Netty Eksiksiz bir şikayet içermeyen bir blok okur eğer yığın halinde olarak, o zaman hiçbir olmasa bile, işaretlediğini İstekte Aktarım Kodlama başlığı.

iki olası çözümler Bunun için vardır: o yığın halinde istek ve ekleyerek "tsd.http reddetmek kalmaması

• , yapılandırma dosyasına "tsd.http.request.enable_chunked = true" ekleyerek .request.max_chunk = "yapılandırma dosyasına ve isteklerinize için mantıklı bir boyuta ayarı
• Eğer müşteri değiştirebiliyorsanız, göndermek için zorlamak küçük istekleri

lütfen unutmayın için yığın halinde istekleri sağlayan kamuya bakan sunucular, iyi bir fikir olmayabilir. İstemci, sınırsız istekleri göndererek sunucuyu aşırı yükleyebilir.
