监控案例实战 -- Zabbix 监控 Nginx 当前的活动连接数

前言

本环境是基于 Centos 7.8 系统构建 Zabbix 学习环境
安装 Zabbix-4.4.10 具体参考：Zabbix-4.4.10 环境部署

一、zabbix-agent 配置

部署 nginx

# 部署 nginx
[root@linux-rhel-7 ~]# yum install nginx -y

修改 nginx 配置文件

[root@linux-rhel-7 ~]# vim /etc/nginx/nginx.conf
... ...

        location /status {
                stub_status on;
                access_log off;
                allow 192.168.5.0/24;
                deny all;
                }

... ...

[root@linux-rhel-7 ~]# systemctl restart nginx

编写监控脚本

[root@linux-rhel-7 ~]# vim /scripts/check_nginx.sh
#!/bin/bash
HOST=192.168.5.12
PORT="80"
# 检测 nginx 进程是否存在


function ping {
/sbin/pidof nginx | wc -l
}
# 检测 nginx 性能
function active {
/usr/bin/curl -s http://$HOST/status | awk '/Active/ {print $3}'
}
function reading {
/usr/bin/curl -s http://$HOST/status | awk '/Reading/ {print $2}'
}
function writing {
/usr/bin/curl -s http://$HOST/status | awk '/Writing/ {print $4}'
}
function waiting {
/usr/bin/curl -s http://$HOST/status | awk '/Waiting/ {print $6}'
}
function accepts {
/usr/bin/curl -s http://$HOST/status | awk 'NR==3 {print $1}'
}
function handled {
/usr/bin/curl -s http://$HOST/status | awk 'NR==3 {print $2}'
}
function requests {
/usr/bin/curl -s http://$HOST/status | awk 'NR==3 {print $3}'
}

修改 zabbix-server 配置文件

[root@linux-rhel-7 ~]# vim /etc/zabbix/zabbix_agentd.d/UserParameter_nginx.conf
UserParameter=nginx.status[*], /scripts/check_nginx.sh $1

[root@linux-rhel-7 ~]# systemctl restart zabbix-agent.service

二、zabbix-server 配置

浏览器登录：http://192.168.5.11/zabbix

导入nginx监控模板



选择导入的模板

三、采集数据

多次高并发访问 nginx
