How to prevent Amazon ELB sits in front of RabbitMQ close connection with celery? -

-

  1. ईएलबी 60 सेकंड के लिए स्वत: बंद कनेक्शन, टीसीपी कनेक्शन स्विच के साथ CLOSE_WAIT स्थिति में
  2. हालांकि, अजवाइन पर ध्यान नहीं दिया जाता है और कार्य संदेश प्रकाशित नहीं होता
  3. संदेश भेज बफर में रखा जाएगा
  4. जब बफर भरा हुआ हो, अजवाइन प्रकाशन कॉल को अवरुद्ध किया जाएगा।
    • भेजें बफर में संदेश खो जाएगा
    • ब्लॉकिंग प्रकाशन कॉल एकल धागा ioloop चौखटे के लिए बहुत हानिकारक होगा जैसे टोरनेडो

      समाधान

      • BROKER_TRANSPORT_OPTIONS = {'Confirm_publish': true} प्रत्येक प्रकाशन संदेश के लिए अजगर की प्रतीक्षा करने के लिए, यदि एक नहीं मिलता है, तो यह कनेक्शन फिर से निर्मित करेगा और फिर से भेज देगा। केवल py-amqp (), प्रदर्शन डाउनग्रेड पर लागू होते हैं।
      • कनेक्शन सक्रिय रखने और ईएलबी के ऑटो क्लोज़ कनेक्शन से बचने के लिए अतिरिक्त नेटवर्क ओवरहेड जोड़ें, दिल की धड़कन खराब नेटवर्क परिवेश में दोनों ही अंत तक वितरित नहीं हो सकता है और यह समाधान काम नहीं कर रहा है।

logging - How can I log both the Request.InputStream and Response.OutputStream traffic in my ASP.NET MVC3 Application for specific Actions? -

-
For a specific set of tasks, I need to log in to the incoming request inputstream as well as outgoing response. is. I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ... Public category ActionLoggerAttribute: ActionFilterArrbit {Public Override Zero On-Offed Execution (ActionActioned Contact Filter Filter) {base.OnActionAxecuted (FilterContext); HttpRequestBase request = filterContext.HttpContext.Request; // TODO: Log the request. InputStream} Public Override Zero OnResultExecuted (ResultExecutedContext FilterContext) {base.OnResultExecuted (filterContext); HTTPRPSPointBase Response = FilterContacts Hpptex response; // TODO: Log on Response.OutputStream}} Ideally I'll hook it up with enterprise library logging because I'm already using it for error logging.
