举一反三-zabbix监控nginx

news2024/11/13 14:32:48

监控nginx需要修改nginx配置文件，添加如下：

location /nginx_status {
stub_status;
allow 127.0.0.1;
allow 192.168.1.71;
deny all;
}

这里边192.168.1.71是这台服务器的IP。

保存退出，重启nginx服务。

编写nginx监控脚本，下面是一个范例：

#!/bin/bash
nginx_status_fun(){
NGINX_PORT=$1
NGINX_COMMAND=$2
nginx_active(){
   /usr/bin/curl "http://127.0.0.1:"$NGINX_PORT"/nginx_status/" 2> /dev/null| grep 'Active' | awk '{print $NF}'
   }
nginx_reading(){
   /usr/bin/curl "http://127.0.0.1:"$NGINX_PORT"/nginx_status/" 2> /dev/null | grep 'Reading' | awk '{print $2}'
   }
nginx_writing(){
   /usr/bin/curl "http://127.0.0.1:"$NGINX_PORT"/nginx_status/" 2> /dev/null | grep 'Writing' | awk '{print $4}'
   }
nginx_waiting(){
   /usr/bin/curl "http://127.0.0.1:"$NGINX_PORT"/nginx_status/" 2> /dev/null | grep 'Waiting' | awk '{print $6}'
   }
nginx_accepts(){
   /usr/bin/curl "http://127.0.0.1:"$NGINX_PORT"/nginx_status/" 2> /dev/null | awk NR==3 | awk '{print $1}'
   }
nginx_handled(){
   /usr/bin/curl "http://127.0.0.1:"$NGINX_PORT"/nginx_status/" 2> /dev/null | awk NR==3 | awk '{print $2}'
   }
nginx_requests(){
   /usr/bin/curl "http://127.0.0.1:"$NGINX_PORT"/nginx_status/" 2> /dev/null | awk NR==3 | awk '{print $3}'
       }
case $NGINX_COMMAND in
   active)
           nginx_active;
           ;;
       reading)
           nginx_reading;
       ;;
writing)
nginx_writing;
   ;;
waiting)
       nginx_waiting;
       ;;
       accepts)
           nginx_accepts;
           ;;
       handled)
           nginx_handled;
           ;;
       requests)
           nginx_requests;
           ;;
   *)
           echo "0"
           ;;
esac
}
main (){
   case $1 in
       nginx_status)
           nginx_status_fun $2 $3;
           ;;
       *)
           echo $"Usage: $0 {nginx_status key}"
   esac
}
main $1 $2 $3
