zabbix部署网络拓扑图
zabbix部署网络拓扑 环境说明
操作系统:Centos7
安装zabbix-release
node1:10.193.116.98 安装zabbix-server模块
node2:10.193.116.97 安装zabbix数据库模块
node3:10.193.116.96 安装zabbix-web模块
node4:10.193.116.95 安装zabbix-proxy模块
node5:10.193.116.94 安装zabbix-agent模块
A机房:zabbix-agent直接连接zabbix-server
B机房:zabbix-agent直接连接zabbix-proxy-
通过ansible进行部署

-
将node5添加监控
配置--->主机-->填写主机名称-->选择群组-->填写接口IP-->选择proxy-->添加模板-->更新
主机添加过程 -
查看node5监控数据
监测-->最新数据-->选择主机-->选择应用集
查看node5内存监控数据 -
windows服务器监控（10.193.116.93）
- 网管下载Windows版本的zabbix-agent
地址：https://www.zabbix.com/cn/download_agents#tab:40LTS
下载Windows版本zabbix-agent -
解析安装包至Windows本地C盘
解压至本地C盘 -
安装
cd "C:\zabbix_agents-4.0.7-win-amd64\bin"
zabbix_agentd.exe -i -c "C:\zabbix_agents-4.0.7-win-amd64\conf\zabbix_agentd.conf"
安装
- 网管下载Windows版本的zabbix-agent
-
启动
命令行启动：
zabbix_agentd.exe -s -c "C:\zabbix_agents-4.0.7-win-amd64\conf\zabbix_agentd.conf"
启动命令
或者通过服务管理启动：
zabbix agent 启动管理
-
测试是否获取数据
测试获取angent状态 -
zabbix-web 添加Windows主机，并查看数据
Windows主机状态
Windows host监控数据
2、搭建zabbix服务，监控nginx status
- node5 安装nginx，添加开启nginx状态监控
location /nginx_status {
# Turn on nginx stats
stub_status on;
# I do not need logs for stats
access_log off;
# Security: Only allow access from 192.168.1.100 IP #
allow 127.0.0.1/8;
deny all;
}
- 编写监控脚本
[root@node5 ~]# vim /usr/bin/nginx_status.sh
#!/bin/bash
#
host='127.0.0.1'
port='80'
statusurl='nginx_status'
active(){
curl -s http://${host}:${port}/${statusurl} |awk '/^Active/{print $3}'
}
accepts(){
curl -s http://${host}:${port}/${statusurl} |awk 'NR==3{print $1}'
}
handled(){
curl -s http://${host}:${port}/${statusurl} |awk 'NR==3{print $2}'
}
requests(){
curl -s http://${host}:${port}/${statusurl} |awk 'NR==3{print $3}'
}
reading(){
curl -s http://${host}:${port}/${statusurl} |awk 'NR==4{print $2}'
}
writing(){
curl -s http://${host}:${port}/${statusurl} |awk 'NR==4{print $4}'
}
waiting(){
curl -s http://${host}:${port}/${statusurl} |awk 'NR==4{print $6}'
}

esac
- zabbix-agent 自定义key
[root@node5 ~]# vim /etc/zabbix/zabbix_agentd.d/userparameter_nginx.conf
UserParameter=nginx.statu[*],/usr/bin/nginx_status.sh $1
重启zabbix-agent
[root@node5 ~]# systemctl restart zabbix-agent
-
zabbix-web页面添加nginx_status告警items
nginx_status告警items
配置Nginx_requests来进行说明
首先配置监控项
配置-->模板-->监控项
监控项页面配置
接着进入进程配置页面
设置为每秒更改 -
添加告警
配置-->模板-->触发器
名称：Nginx每秒请求超过100
表达式：
{Centos7-Nginx:nginx.statu[requests].last(#1)}>100
Nginx每秒请求超过100 压测触发告警
安装ab压测工具
[root@node5 ~]# yum -y install httpd-tools
[root@node5 ~]# ab -n 5000 -c 20 http://127.0.0.1/nginx_status
告警触发
采集Nginx_requests数据
