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=
##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=(',',':')))
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"
}
]
}
/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
（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 $ $
（6）导入模板
<?xml version="1.0" encoding="UTF-8"?>

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。
