docker zabbixモニタリングの構築

1、ディレクトリの作成[root@localhost script]# mkdir/usr/local/zabbix/etc/script
2、コンテナ発見スクリプトの編集[root@localhost script]# vim docker_discovery.py#!/usr/bin/env python import osimport simplejson as jsont=os.popen("""sudo docker ps |grep -v 'CONTAINER ID'|awk {'print $NF'} """)container_name = []for container in t.readlines():r = os.path.basename(container.strip())container_name += [{'{#CONTAINERNAME}':r}]print json.dumps({'data':container_name},sort_keys=True,indent=4,separators=(',',':'))
3、インストール環境とテスト自動発見pip install dockerpip install simplejsonchmod 757 docker_discovery.pychown zabbix:zabbix/usr/local/zabbix/etc/script -R

  zabbix  ，  /etc/sudoers,      
    zabbix  ALL=(root)    NOPASSWD:/usr/bin/docker,/usr/bin/python,/usr/local/zabbix/etc/script/docker_discovery.py 

           ：
    vim /usr/local/zabbix/etc/zabbix_agentd.conf
    UserParameter=docker_discovery,sudo /usr/bin/python /usr/local/zabbix/etc/script/docker_discovery.py

  ：
     zabbix_get -s 192.168.199.133 -k docker_discovery 

4、容器監視テストを追加[root@localhost script]# vim docker_monitor.py #!/usr/bin/env pythonimport dockerimport sysimport subprocessimport os

def check_container_stats(container_name,collect_item):
    #docker_client = docker_client.containers.get(container_name)
    container_collect=docker_client.containers.get(container_name).stats(stream=True)
    old_result=eval(container_collect.next())
    new_result=eval(container_collect.next())
    container_collect.close()
    if collect_item == 'cpu_total_usage':
        result=new_result['cpu_stats']['cpu_usage']['total_usage'] - old_result['cpu_stats']['cpu_usage']['total_usage']
    elif collect_item == 'cpu_system_usage':
        result=new_result['cpu_stats']['system_cpu_usage'] - old_result['cpu_stats']['system_cpu_usage']
    elif collect_item == 'cpu_percent':
        cpu_total_usage=new_result['cpu_stats']['cpu_usage']['total_usage'] - old_result['cpu_stats']['cpu_usage']['total_usage']
        cpu_system_uasge=new_result['cpu_stats']['system_cpu_usage'] - old_result['cpu_stats']['system_cpu_usage']
        cpu_num=len(old_result['cpu_stats']['cpu_usage']['percpu_usage'])
        result=round((float(cpu_total_usage)/float(cpu_system_uasge))*cpu_num*100.0,2)
    elif collect_item == 'mem_usage':
        result=new_result['memory_stats']['usage']
    elif collect_item == 'mem_limit':
        result=new_result['memory_stats']['limit']
    elif collect_item == 'network_rx_bytes':
        result=new_result['networks']['eth0']['rx_bytes']
    elif collect_item == 'network_tx_bytes':
        result=new_result['networks']['eth0']['tx_bytes']
    elif collect_item == 'mem_percent':
        mem_usage=new_result['memory_stats']['usage']
        mem_limit=new_result['memory_stats']['limit']
        result=round(float(mem_usage)/float(mem_limit)*100.0,2)
    return result
if __name__ == "__main__":
    docker_client = docker.DockerClient(base_url='unix://var/run/docker.sock', version='1.27')
    container_name=sys.argv[1]
    collect_item=sys.argv[2]
    print check_container_stats(container_name,collect_item)

[root@localhost script]# chmod 757  docker_monitor.py 
         ：vim /usr/local/zabbix/etc/zabbix_agentd.conf
UserParameter=docker_status[*],sudo /usr/bin/python /usr/local/zabbix/etc/script/docker_monitor.py $1 $2

  ：zabbix_get -s 192.168.199.133 -k docker_status[mysql-sonar,cpu_total_usage]

5、web側作成テンプレート5.1、構成-』テンプレート-』作成テンプレート(cpu_percent mem_percent mem_usage mem_limit)Template name:Template Docker Auto Discovery

5.2、    

5.3、         ：      

      ：
Name：collect docker container use resource
Type：Zabbix agent
Key：docker_discovery

   ：
{#CONTAINERNAME}

5.4、       

    Name：container:{#CONTAINERNAME}:cpu_percent
    Type：Zabbix agent
    Key：docker_status[{#CONTAINERNAME},cpu_percent]
    Type：Numeric (float)
    Units：%

    Name：container:{#CONTAINERNAME}:mem_percent
    Type：Zabbix agent
    Key：docker_status[{#CONTAINERNAME},mem_percent]
    Type：Numeric (float)
    Units：% 

    Name：container:{#CONTAINERNAME}:mem_usage
    Type：Zabbix agent
    Key：docker_status[{#CONTAINERNAME},mem_usage]
    Type：  （   ）
    Units： 

    Name：container:{#CONTAINERNAME}:mem_limit
    Type：Zabbix agent
    Key：docker_status[{#CONTAINERNAME},mem_limit]
    Type：  （   ）
    Units：  

5.5、     

5.5、      
Name：container:{#CONTAINERNAME}:cpu      
   ：

6、zabbixクライアントのインストール

        ：
        
#groupadd zabbix
#useradd -g zabbix -m zabbix

#./configure --prefix=/usr/local/zabbix --enable-agent 
#make install

#vi /usr/local/zabbix/etc/zabbix_agentd.conf
