Zabbix企业级监控之监控Nginx

Nginx hailen 862℃

1.如何监控Nginx?

需要添加http_stub_status_module 模块

2.安装Nginx需要的模块

(1)安装依赖包

yum -y install vim gcc wget pcre-devel openssl-devel gcc-c++ pcre-dev  zlib-devel 

(2)安装nginx

wget http://101.96.10.63/nginx.org/download/nginx-1.12.1.tar.gz

解压

tar -zxvf nginx-1.12.1.tar.gz

添加nginx组并添加nginx用户

useradd -M -s /sbin/nologin nginx

(3)编译安装

cd nginx-1.12.1
./configure --prefix=/etc/nginx --user=nginx --group=nginx --with-http_stub_status_module
make && make install

(4)vim nginx.conf

在server {} 添加nginx统计模块

#nginx状态监控
        location /nginx_status {
              stub_status on;
              access_log off;
              allow all;        }

(5)重启nginx

3.重启agent

systemctl restart zabbix-agent

4.添加nginx模板

vim /etc/zabbix/zabbix_agentd.d/userparameter_nginx.conf
UserParameter=nginx_status[*],/bin/bash /etc/zabbix/shell/monitor_nginx.sh "$1"

5.编写shell脚本

vim /etc/zabbix/shell/monitor_nginx.sh

#!/bin/bash

nginx_port=81
nginx_ip=127.0.0.1
curl_addres="http://$nginx_ip:$nginx_port/nginx_status"
nginx_active() {
    curl -s $curl_addres|grep "Active"|awk '{print $3}'
}

nginx_reading() {
   curl -s $curl_addres |grep "Reading"| awk '{print $2}'
}
nginx_writing() {
   curl -s $curl_addres |grep "Writing"|awk '{print $4}'
}

nginx_waiting() {
   curl -s $curl_addres |grep "Waiting"|awk '{print $6}'
}

nginx_accept() {
   curl -s $curl_addres |awk 'NR==3{print $1}'
}
nginx_handled() {
   curl -s $curl_addres |awk 'NR==3{print $2}'
}

nginx_requests() {
   curl -s $curl_addres |awk 'NR==3{print $3}'
}

case $1 in 
    nginx_active)
        nginx_active;
    ;;
    nginx_reading)
        nginx_reading;
    ;;
    nginx_writing)
        nginx_writing;
    ;;
    nginx_waiting)
        nginx_waiting;
    ;;
    nginx_accept)
        nginx_accept;
    ;;
    nginx_handled)
        nginx_handled;
    ;;
    nginx_requests)
        nginx_requests;
    ;;
    *)
esac
