• 假如有几个队列，那么作图的时候会有点麻烦，写个小脚本，生成falcon里面的规则

#!/bin/bash

for line in `cat 1`
do
    echo 
    echo 
    part1=`echo $line | awk '{print $1}'`
    for line2 in `cat 2`
    do
        part2=`echo $line2 | awk '{print $1}'`
        echo "$part1/$part2"
    done
done

• rabbitmq-monitor可以提供的指标

rabbitmq.ack_rate
rabbitmq.deliver_get_rate
rabbitmq.deliver_rate
rabbitmq.messages_ready
rabbitmq.messages_total //这个指标重要，我们是高于5k就报警
rabbitmq.messages_unacknowledged
rabbitmq.publish_rate
