لدي عدد قليل من مثيلات Discourse التي كانت تعمل لفترة طويلة جدًا دون مشاكل. مؤخرًا انتقلت إلى Hetzner من DO. كجزء من الانتقال، بدأت أخيرًا في المراقبة، باستخدام Uptime في الوقت الحالي. قمت بتأمين الخوادم باستخدام Ubuntu USG.
ثلاثة من أصل 7 مثيلات تنقطع عن العمل بشكل روتيني لمدة 5 إلى 15 دقيقة في نفس الوقت تقريبًا يوميًا. ربما كان هذا يحدث على DO ولكن بدون مراقبة، من يدري.
جميع المواقع تعمل بنفس مجموعة الإضافات الرسمية.
اشتبهت في وجود مشكلة في الذاكرة وقمت بترقية مثيل واحد من 2 CPU و 2GB RAM إلى 3 CPU مع 4GB RAM
لم يتغير db_shared_buffers: “256MB”
لم يتغير UNICORN_WORKERS: 4
يبدو أن الأداء المتزايد قد ساعد، ولكن هل أحتاج إلى الكثير من الموارد على موقع هادئ جدًا؟
أي أفكار أو اقتراحات ستكون موضع تقدير.
