zabbix监控nginx

一、实验准备

二、监控nginx

一、实验准备

zabbix-sever（192.168.115.4）

zabbix-agent（192.168.115.5）

添加监控对象

二、监控nginx

安装NGINX在192.168.115.5上安装NGINX，开启status模块

yum -y install epel-release

yum -y install nginx

systemctl start nginx

nginx -V #查看模块

编写nginx的配置文件vim /etc/nginx/nginx.conf

server或者location下插入
location / {
}
location /status {                   #定义运行状态页面名称，页面为statusstub_status on;              #开启模块access_log off;              #不开启访问日志记录allow 192.168.115.0/24;      #允许此网段的主机访问此网页deny all;                    #其余网段主机不允许访问}

重启：systemctl restart nginx

验证此模块：curl 192.168.115.151/status

编写脚本、设置key并验证

vim /etc/zabbix/nginx.sh

#!/bin/bash
#定义Nginx status页面
ngx_status="192.168.115.5/status"#判断status页面是否存活
ngx_status_code() {http_code=`curl -o /dev/null -s -w %{http_code} ${ngx_status}`if [ ${http_code} == "200" ];thenreturn 1elseecho "Nginx status is not running."fi
}#获取当前活动的客户端连接数
active() {ngx_status_code || curl -s ${ngx_status} | grep "Active" | awk '{print $NF}'
}#获取接收客户端连接的总数量
accepts() {ngx_status_code || curl -s ${ngx_status} | awk NR==3 | awk '{print $1}'
}#获取已处理的连接总数量
handled() {ngx_status_code || curl -s ${ngx_status} | awk NR==3 | awk '{print $2}'
}#获取客户端请求总数量
requests() {ngx_status_code || curl -s ${ngx_status} | awk NR==3 | awk '{print $3}'
}#获取正在读取请求标头的当前连接数量
reading() {ngx_status_code || curl -s ${ngx_status} | grep "Reading" | awk '{print $2}'
}#获取正在将响应写回到客户端的当前连接数量
writing() {ngx_status_code || curl -s ${ngx_status} | grep "Writing" | awk '{print $2}'
}#获取当前正在等待响应的客户端连接数量
waiting() {ngx_status_code || curl -s ${ngx_status} | grep "Waiting" | awk '{print $2}'
}#使用位置变量控制脚本输出
case $1 inactive)active;;accepts)accepts;;handled)handled;;requests)requests;;reading)reading;;writing)writing;;waiting)waiting;;*)echo "Unknown options"
esac

配置Zabbix Agent

vim /etc/zabbix/zabbix_agentd.conf

将333行UnsafeUserParameters=0解开注释并改成UnsafeUserParameters=1

在底端添加创建自定义监控项

UserParameter=nginx.active,bash /etc/zabbix/nginx.sh active
UserParameter=nginx.accepts,bash /etc/zabbix/nginx.sh accepts
UserParameter=nginx.handled,bash /etc/zabbix/nginx.sh handled
UserParameter=nginx.requests,bash /etc/zabbix/nginx.sh requests
UserParameter=nginx.reading,bash /etc/zabbix/nginx.sh reading
UserParameter=nginx.writing,bash /etc/zabbix/nginx.sh writing
UserParameter=nginx.waiting,bash /etc/zabbix/nginx.sh waiting
