Related question:Get queue size from rabbitmq consumer's callback with PhpAmqpLib
In the above question the message count is obtained by queue_declare. However this message count only counts messages that are in the queue, but not the prefetched messages (which is exactly what the poster of that question is experiencing)
If I set the prefetch_count (in basic_qos) to 1 and send ack for every single message then the message count works perfectly, but if I set the prefetch_count to 10 and send ack for every 5 messages then the message count will be something like 100, 100, 100, 100, 100, 95, 95, 95, 95, 95, ... when each message is handled.
What I want is to get the number of prefetched messages as well and add them up so that I will have the correct message count, including prefetched not but processed messages, when each message is handled.
Is there a way to obtain this number of cached messages in php-amqplib?
