Zabbix监控ActiveMQ

当我们在线上使用了ActiveMQ 后，我们需要对一些参数进行监控，比如 消息是否有阻塞，哪个消息队列阻塞了，总的消息数是多少等等。下面我们就通过 Zabbix 结合 Python 脚本来实现对 ActiveMQ的监控。

一、创建 Activemq Python 监控脚本

因为 CentOS 系统默认安装的是 Python2.7，为了避免麻烦，我们这里的脚本也是对应的 Python2

Python2 监控脚本

import logging
import sys


def activemq_mointer(userinfo_encode):
    # 总的消息阻塞数
    pending_queue_sum = 0
    # 阻塞消息的队列名称
    pending_queue_lists = ''
    # 总的消息数
    mq_sum = 0
    headers = {
        'Authorization': 'Basic {}'.format(userinfo_encode),
        'ua': 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/44.0.2403.125 Safari/537.36'
    }
    url = 'http://' + ip + ':' + port + \
          '/api/jolokia/read/org.apache.activemq:type=Broker,brokerName=localhost/Queues/'
    request = urllib2.Request(url=url, headers=headers)
    try:
        response = urllib2.urlopen(request)
    except Exception as e:
        logging.error(e)
        return {'pending_queue_sum': 110, 'pending_queue_lists': '110', 'mq_sum': 0}  # 当服务不可用时，返回预警数字，用于预警。
    activemq_info = response.read()
    activemq_info_json = json.loads(activemq_info)
    activemq_queues = activemq_info_json['value']
    for i in activemq_queues:
        queue_url = 'http://' + ip + ':' + port + \
            '/api/jolokia/read/' + i['objectName']
        queue_request = urllib2.Request(url=queue_url, headers=headers)
        try:
            queue_response = urllib2.urlopen(queue_request)
        except Exception as e:
            logging.error(e)
            return {'pending_queue_sum': 110, 'pending_queue_lists': '110', 'mq_sum': 0}
        queue_info = queue_response.read()
        info_dict = json.loads(queue_info)
        mq_sum += info_dict['value']['EnqueueCount']
        if int(info_dict['value']['QueueSize']
               ) > 0:  # 取值 QueueSize ，就是未消费的消息数量
            pending_queue_sum += info_dict['value']['QueueSize']
            pending_queue_lists += info_dict['value']['Name']
            pending_queue_lists += ' and '
            logging.info(
                "消息队列--{}--有阻塞消息--{} 条".format(
                    info_dict['value']['Name'],
                    info_dict['value']['QueueSize']))
    return {'pending_queue_sum': pending_queue_sum, 'pending_queue_lists': pending_queue_lists, 'mq_sum': mq_sum}


if __name__ == '__main__':
    # ActiveMQ 服务器信息
    username = 'admin'
    password = 'admin'
    ip = '127.0.0.1'
    port = '8161'
    userinfo = username + ':' + password
    userinfo_encode = base64.b64encode(userinfo.encode('utf8'))
    # 日志配置,注意下面日志文件的路径是采用相对路径的。
    logging.basicConfig(
        filename="/var/log/activemq_mointer.log",
        filemode="a",
        format="%(asctime)s %(name)s:%(levelname)s:%(message)s",
        datefmt="%d-%M-%Y %H:%M:%S",
        level=logging.DEBUG)
    if len(sys.argv) == 2:
        mointer_argv = sys.argv[1]
        if mointer_argv in ('pending', 'pending_lists', 'queue_sum'):
            mq_re = activemq_mointer(userinfo_encode)
            if mointer_argv == 'pending':
                print(mq_re['pending_queue_sum'])
            elif mointer_argv == 'pending_lists':
                print(mq_re['pending_queue_lists'])
            else:
                print(mq_re['mq_sum'])
        else:
            # 错误提示
            print("Please enter the correct parameters pending|pending_lists|queue_sum")
    else:
        # 错误提示
        print("Please enter the correct parameters pending|pending_lists|queue_sum")

使用该脚本注意事项：

1. 传入参数只能一个 ，而且只能是 pending, pending_lists, queue_sum ，分别代表阻塞消息数、阻塞消息队列名称、总的消息数。

2. 脚本有日志记录和异常记录，注意设置 日志文件路径，假设脚本路径位于 /opt/scripts/,我们在该目录下进行执行脚本的话，activemq_mointer.log 日志文件也就会产生在当前目录下。我们可以在路径中通过绝对路径来指定文件夹 形如 /var/log/activemq_mointer.log

3. 该脚本是由 zabbix agent 进行使用 ，所以我们需要设置该 脚本的权限，以及保证该脚本的用户有创建日志文件的权限(或者我们先前创建好对应权限日志文件)

   sudo chown  zabbix:zabbix  mointer_mq_python2.py
   sudo  chmod 744 mointer_mq_python2.py
   sudo  touch /var/log/activemq_mointer.log
   sudo chown  zabbix:zabbix  /var/log/activemq_mointer.log

        except Exception as e:
            logging.error(e)
            return {'pending_queue_sum': 110, 'pending_queue_lists': '110', 'mq_sum': 0}
        info_dict = queue_info.json()
        mq_sum += info_dict['value']['EnqueueCount']
        if int(info_dict['value']['QueueSize']) > 0:  # 取值 QueueSize ，就是未消费的消息数量
            pending_queue_sum += info_dict['value']['QueueSize']

            pending_queue_lists += ' and '
            logging.info(
                "Queues--{}--peding msg --{}".format(
                    info_dict['value']['Name'],
                    info_dict['value']['QueueSize']))
    return {'pending_queue_sum': pending_queue_sum, 'pending_queue_lists': pending_queue_lists, 'mq_sum': mq_sum}

if __name__ == '__main__':
    # ActiveMQ 服务器信息
    username = 'admin'
    password = 'admin'
    ip = '127.0.0.1'
    port = '8161'
    userinfo = username + ':' + password
    userinfo_encode = base64.b64encode(userinfo.encode('utf8'))
    # 日志配置
    logging.basicConfig(
        filename="/var/log/activemq_mointer.log",
        filemode="a",
        format="%(asctime)s %(name)s:%(levelname)s:%(message)s",
        datefmt="%Y-%m-%d %H:%M:%S",
        level=logging.INFO)
    if len(sys.argv) == 2:
        mointer_argv = sys.argv[1]
        if mointer_argv in ('pending', 'pending_lists', 'queue_sum'):
            mq_re = activemq_mointer(userinfo_encode)
            if mointer_argv == 'pending':
                print(mq_re['pending_queue_sum'])
            elif mointer_argv == 'pending_lists':

    else:
        # 错误提示
        print("Please enter the correct parameters pending|pending_lists|queue_sum")

二 、设置 zabbix agent

设置 zabbix agent

# 将监控项配置写入配置文件
sudo echo "UserParameter=activemq.mointer[*],python /opt/scripts/mointer_mq_python2.py \$1 " >> /opt/zabbix-agent/etc/zabbix_agentd.conf
# 重启zabbix agent
sudo systemctl restart  zabbix-agent 

三、导入监控项：

监控模板 xml 文件。(该监控模板包含三个监控项，一个触发器)
