zabbix监控docker容器

1、环境说明

由于最近zabbix进行过一次迁移,所以zabbix-server系列采用docker方式安装,参考zabbix官网:https://github.com/zabbix/zabbix-docker。为适应本地环境和需求,docker-compose.yml文件有改动,具体内容如下:

docker-compose.yml文件

version: '3.5'
services:
 zabbix-server:

2、zabbix添加自定义监控

(1)zabbix_server.conf配置

#脚本路径
AlertScriptsPath=/usr/lib/zabbix/alertscripts ExternalScripts=/usr/lib/zabbix/externalscripts

(2)zabbix_agent.conf配置

##允许使用用户自定义参数
UnsafeUserParameters=1
##导入该文件下的配置
Include=/etc/zabbix/zabbix_agentd.d/*.conf

(3)自定义监控脚本

/usr/lib/zabbix/externalscripts/docker_discovery.py,搜集正在运行的容器的名称

#!/usr/bin/env python
# -*- coding: utf-8 -*
import os
import simplejson as json
t=os.popen("""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=(',',':')))
View Code

安装python3 所需要的包

pip3 install simplejson

docker_discovery.py执行结果

python3 docker_discovery.py
{
    "data":[
        {
            "{#CONTAINERNAME}":"nginx"
        },
        {
            "{#CONTAINERNAME}":"fortune"
        }
    ]
}
View Code

/usr/lib/zabbix/externalscripts/docker_monitor.py,输入容器名称以及监控项,输出数据

#!/usr/bin/env python
import docker
import sys
import subprocess
import os

def check_container_stats(container_name,collect_item):
    
    if collect_item == "ping":
        cmd = 'docker inspect --format="{{.State.Running}}" %s' % container_name
        result = os.popen(cmd).read().replace("\n","")
        if result == "true":
            return 1
        else:
            return 0

    #:docker_client = docker_client.containers.get(container_name)
    container_collect=docker_client.containers.get(container_name).stats(stream=True)
    old_result=eval(next(container_collect))
    new_result=eval(next(container_collect))
    print(new_result)
    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')
    container_name=sys.argv[1]
    collect_item=sys.argv[2]
    print(check_container_stats(container_name,collect_item)

安装python3依赖的包

pip3 install docker

docker_monitor.py执行结果

python3 docker_monitor.py nginx mem_percent
0.49
View Code

(4)脚本赋执行权限

chmod +x docker_discovery.py
chmod +x docker_monitor.py

(5)自定义监控配置文件

/etc/zabbix/zabbix_agentd.d/docker_discovery.conf 
UserParameter=docker_discovery,/usr/bin/python3 /usr/lib/zabbix/externalscripts/docker_discovery.py
UserParameter=docker_status[*],/usr/bin/python3 /usr/lib/zabbix/externalscripts/docker_monitor.py $1 $2

 (6)导入模板

模板导入成功后,查看监控项是否可用,注意客户端版本是否和文章一致,这里的zabbix所有版本均为4.2,若有问题可留言讨论。

3、问题整理

由于原本客户端python是2.7版本,在执行docker_monitor.py时有如下报错,后来知道是python版本问题,升级python3以后执行成功。

# python docker_monitor.py
Traceback (most recent call last): File "docker_monitor.py", line 36, in
<module> docker_client = docker.DockerClient(base_url='unix://var/run/docker.sock') AttributeError: 'module' object has no attribute 'DockerClient'

(1)python2升级步骤

#安装python3.6
yum -y install epel-release
yum install https://centos7.iuscommunity.org/ius-release.rpm ##安装centos7的ius源
yum install python36u -y ln -s /usr/bin/python3.6 /bin/python3 #安装pip3 yum install python36u-pip -y ln -s /usr/bin/pip3.6 /bin/pip3 pip3 install --upgrade pip ##有些情况安装完python3之后就不需要再安装pip3

(2)升级python3后,simplejson和docker-py需要重装

pip3 install simplejson
#docker-py最新版改名为docker
pip3 install docker

(3)zabbix-serve端测试时报错

zabbix_get -s 10.8.0.22 -p 10050 -k  docker_status[reids,cpu_percent]

从错误可以看出是权限问题,解决办法:

#查看docker.sock用户权限
ls /var/run/docker.sock -lh
srw-rw---- 1 root docker 0 9月   2 17:04 /var/run/docker.sock
#将zabbix用户加入docker所在组
gpasswd -a zabbix docker

zabbix_get测试连接

 zabbix_get -s 10.8.0.22 -p 10050 -k  docker_status[redis,mem_percent]
0.3

以上所有内容均为亲自测试成功后才写的,那些踩的最深的坑都已经都修改,大可放心使用。
