Linux下Zabbix监控之Nginx监控添加

nginx_status配置

• conf配置开启nginx status监控

#由于使用的是vhost虚拟主机，故新建一个conf文件
server {
    listen  80;
    server name localhost;

    location /ngx_status {
        stub_status on;
        access_log off;
        allow 127.0.0.1;
        deny all;
    }

• 重启nginx

systemctl restart nginx.service

• 测试status

curl http://127.0.0.1/ngx_status
Active connections: 1
server accepts handled requests request_time
 22884 22884 11890 71698
Reading: 0 Writing: 1 Waiting: 0

• 数据介绍

Active connections：1    #活跃的连接数量 
server accepts handled requests request_time  #总共处理了22884个请求，成功建立22884次握手，总共处理11890个请求；request_time指的就是从接受用户请求的第一个字节到发送完响应数据的时间，即包括接收请求数据时间、程序响应时间、输出响应数据时间。
            22884    22884     11890     71698
reading  #读取客户端的连接数
writing  #响应数据到客户端的数量
waiting  #开启 keep-alive 的情况下,这个值等于active-(reading+writing),意思就是Nginx已经处理完正在等候下一次请求指令的驻留连接

zabbix-agent添加nginx监控

• zabbix-agent上nginx数据获取脚本

#!/bin/bash
HOST="127.0.0.1"
PORT="80"
KEYWORD="ngx_status"
URL="http://$HOST:$PORT/$KEYWORD/"
 
#参数是否正确
if [ $# -ne "1" ];then
    echo "arg error!"
fi

#获取数据
case $1 in
    active)
        result=`/usr/bin/curl $URL 2>/dev/null| grep 'Active' | awk '{print $NF}'`
        echo $result
        ;;      
    reading)
        result=`/usr/bin/curl $URL 2>/dev/null| grep 'Reading' | awk '{print $2}'`
        echo $result
        ;;      
    writing)
        result=`/usr/bin/curl $URL 2>/dev/null| grep 'Writing' | awk '{print $4}'`
        echo $result
        ;;      
    waiting)
        result=`/usr/bin/curl $URL 2>/dev/null| grep 'Waiting' | awk '{print $6}'`
        echo $result
        ;;      
    accepts)
        result=`/usr/bin/curl $URL 2>/dev/null| awk NR==3 | awk '{print $1}'`
        echo $result
        ;;      
    handled)
        result=`/usr/bin/curl $URL 2>/dev/null| awk NR==3 | awk '{print $2}'`
        echo $result
        ;;      
    requests)
        result=`/usr/bin/curl $URL 2>/dev/null| awk NR==3 | awk '{print $3}'`
        echo $result
        ;;      
    ping)
        result=`/sbin/pidof nginx | wc -l`
        echo $result
        ;;
    request_time)
        result=`/usr/bin/curl $URL 2> /dev/null|awk NR==3|awk '{print $4}'`
        echo $result
        ;;
    *)  
    echo "Usage:$0(ping|active|reading|writing|waiting|accepts|handled|requests|request_time)"  
    ;;
esac

• userparameter_nginx.conf配置

vim /etc/zabbix/zabbix_agentd.d/userparameter_nginx.conf
UserParameter=nginx.status[*],/etc/zabbix/scripts/ngx_status.sh $1

• 重启zabbix-agent服务

systemctl restart zabbix-agent.service
