Zabbix【部署 03】zabbix-agent2安装配置使用（zabbix-agent2监控docker实例分享)

1.安装agent2

bash 复制代码

# 1.选择合适的安装库
rpm -Uvh https://repo.zabbix.com/zabbix/5.0/rhel/7/x86_64/zabbix-release-5.0-1.el7.noarch.rpm
yum clean all
# 2.安装zabbix-agent2
yum install -y zabbix-agent2
# 3.启动并设置开启启动
systemctl restart zabbix-agent2
systemctl enable zabbix-agent2

2.配置

2.1 docker配置

bash 复制代码

# 如果不进行docker配置 zabbix_get 无法获取数据
# zaabix_server 更无法获取数据
[root@tcloud zabbix]# zabbix_get -s 127.0.0.1 -k docker.info
ZBX_NOTSUPPORTED: Unsupported item key.

# 1.查看docker 分组下的所有用户
grep 'docker' /etc/group

# 2.创建用户组
groupadd docker

# 3.将zabbix添加到用户组
usermod -aG docker zabbix

# 4.重启docker服务【重启命令根据实际情况执行】
systemctl restart docker

2.2 agent2配置

● See Zabbix template operation for basic instructions.

bash 复制代码

# 1.修改配置文件
vim zabbix_agent2.conf
	# 服务端IP地址【根据实际情况配置】
	Server=127.0.0.1
	# 如果部署了agent需要修改agent2的端口号
	ListenPort=20050
	# 主动注册指向服务端【根据实际情况配置】
	ServerActive=127.0.0.1
	# 启用Docker插件
	Plugins.Docker.Endpoint=unix:///run/docker.sock

● Setup and configure zabbix-agent2 compiled with the Docker monitoring plugin. ● Test availability: zabbix_get -s docker-host -k docker.info

bash 复制代码

# 2.重启 agent2 服务
systemctl restart zabbix-agent2

[root@tcloud zabbix]# zabbix_get -s 127.0.0.1 -k docker.info

3.使用

使用Template App Docker模板，具体配置不再赘述。

4.小小的总结

本文介绍了使用Zabbix-Agent2监控Docker的配置流程。首先通过yum安装Zabbix-Agent2并设置开机自启。然后进行关键配置：

1)将zabbix用户加入docker组以获取权限；
2)修改agent2配置文件，启用Docker插件并指定sock路径。配置完成后，使用zabbix_get命令测试成功获取docker.info信息，验证配置生效。

最后只需在Zabbix服务端应用Docker模板即可实现监控。整个流程解决了ZBX_NOTSUPPORTED错误问题，为Docker容器监控提供了完整的解决方案。
