RabbitMQ को operate करने के लिए key metrics (queue depth, message rates, consumer health, resources) को monitor करना और management tools का उपयोग करना आवश्यक है। RabbitMQ को विश्वसनीय रूप से चलाने के लिए monitoring और management को समझना महत्वपूर्ण है।
Monitor करने योग्य key metrics
✓ QUEUE DEPTH (length) → growing queues = consumers can't keep up (a key signal!) — like
consumer lag; investigate (add consumers, fix slow processing)
✓ MESSAGE RATES → publish rate vs deliver/ack rate (in vs out — are they balanced?)
✓ CONSUMER count and health → are consumers connected and processing?
✓ UNACKED messages → many unacked = slow/stuck consumers
✓ RESOURCES → memory, disk, CPU, connections, file descriptors (RabbitMQ has memory/disk
alarms that block publishing when thresholds are hit!)
✓ DEAD LETTER queue size → failed messages accumulating (signals problems)
