概述

今天主要介紹一下zabbix怎么去自定義key來監控rabbitmq隊列。

---

一、環境準備腳本

1、每秒鐘插入一個觀察隊列情況(queues.py)

# -*- coding: utf-8 -*-import pikaimport timecredentials = pika.PlainCredentials('hwb', 'xxx')connection = pika.BlockingConnection(pika.ConnectionParameters('127.0.0.1',5672,'/',credentials))channel = connection.channel()queuename="hwb"channel.queue_declare(queue=queuename)i = 1while True: channel.basic_publish(exchange='', routing_key=queuename, body='hwb body {0}'.format( i )) print("insert hwb body success") time.sleep(1) i = i + 1

2、消費者程序(rabbitconsumer.py)

# -*- coding: utf-8 -*-import pikacredentials = pika.PlainCredentials('hwb', 'xxx')connection = pika.BlockingConnection(pika.ConnectionParameters('127.0.0.1',5672,'/',credentials))channel = connection.channel()queuename="hwb"channel.queue_declare(queue=queuename)def callback(ch, method, properties, body): print("Received %r" % body)channel.basic_consume(callback,queue=queuename,no_ack=True)print('Consume waiting for messages. To exit press CTRL+C')channel.start_consuming()

二、Rabbitmq監控腳本

1、Python獲取隊列信息(/etc/zabbix/zabbix_agentd.d/rabbitmqmonitor.py)

# -*- coding: utf-8 -*-try: import jsonexcept: import simplejson as jsonimport commands (status, output) = commands.getstatusoutput("""curl -s -u hwb:fxxx http://127.0.0.1:15672/api/queues""")outputjson = json.loads(output)for one in outputjson: print(one['name']) print(one['messages_ready']) if(one.has_key('message_stats')): if(one['message_stats'].has_key('deliver_get')): print(one['message_stats']['deliver_get']) continue print(0)

分別輸出：namemessages_readydeliver_get信息

2、Shell監控腳本：(/etc/zabbix/zabbix_agentd.d/rabbitmq_check.sh)

#!/bin/bashqueuename=$1queuetype=$2result=$(python /etc/zabbix/zabbix_agentd.d/rabbitmqmonitor.py)case $2 in "unread" ) echo "$result" |grep "^$queuename$" -A 2 |awk 'NR==2';; "read" ) echo "$result" |grep "^$queuename$" -A 2 |awk 'NR==3';; *) echo "unsupport key";;esac

測試監控腳本

./rabbitmq_check.sh hwb read

./rabbitmq_check.sh hwb unread

3、自定義Key腳本(/etc/zabbix/zabbix_agentd.d/rabbitmq.conf)

?UserParameter=rabbitmq.status[*],sh /etc/zabbix/zabbix_agentd.d/rabbitmq_check.sh $1 $2

4、zabbix_get測試

?zabbix_get -s xxx -k rabbitmq.status[hwb,unread]

---

三、zabbix網頁添加監控項

--未讀隊列名稱：queue $1 $2鍵值：rabbitmq.status[hwb,unread]類型：數字單位：更新間隔：60s--每秒鐘處理的隊列數名稱：queue $1 $2 persecond鍵值：rabbitmq.status[hwb,read]類型：浮點數單位：更新間隔：60s進程:每秒更改

---

四、zabbix網頁添加觸發器

--未讀隊列超過xxx告警 -> 監控業務有沒有在正常處理名稱：hwb queue unread>100嚴重性：嚴重表達式：{mq.jk:rabbitmq.status[hwb,unread].last()}>100--每秒鐘處理的隊列數超過xx告警 -> 監控業務的并發的能力名稱：hwb queue read persecond > 200嚴重性：嚴重表達式：{mq.jk:rabbitmq.status[hwb,read].last()}>200

---

五、測試

模擬產生隊列達到100觸發告警

告警郵件如下：

修復郵件如下：
