Given the command rabbitmqctl list_queues name messages_ready messages_unacknowledged, what output would indicate a potential problem?
AQueue 'task_queue' shows 1000 messages_ready and 0 messages_unacknowledged
BQueue 'task_queue' shows 0 messages_ready and 0 messages_unacknowledged
CQueue 'task_queue' shows 10 messages_ready and 5 messages_unacknowledged
DQueue 'task_queue' shows 2 messages_ready and 3 messages_unacknowledged
Step-by-Step Solution
Solution:
Step 1: Understand message states
High messages_ready means many messages waiting to be processed, which can cause delays.
Step 2: Analyze options for potential issues
The output where Queue 'task_queue' shows 1000 messages_ready and 0 messages_unacknowledged indicates a large backlog, as many messages are waiting to be processed.
Final Answer:
Queue 'task_queue' shows 1000 messages_ready and 0 messages_unacknowledged -> Option A
Quick Check:
High messages_ready = potential backlog [OK]
Quick Trick:High messages_ready means backlog risk [OK]
Common Mistakes:
MISTAKES
Ignoring large message counts
Confusing messages_ready with messages_unacknowledged
Assuming zero unacknowledged means no problem
