# 1.nginx七种status详解 #

*  Active：活跃的连接数量
 *  accepts：总共处理了多少个连接
 *  handled：成功创建多少次握手
 *  requests：总共处理了多少个请求
 *  Reading：读取客户端的链接数
 *  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.

# 2.在zabbix-02上部署nginx。 #

## 2.1使用yum源安装（重点不是nginx安装） ##

[root@zabbix-02 ~]# yum install nginx -y（先装epel源）
    [root@zabbix-02 ~]# cat /etc/nginx/nginx.conf
    worker_processes  1;
    events {
        worker_connections  1024;
    }
    http {
        include       mime.types;
        default_type  application/octet-stream;
        sendfile        on;
        keepalive_timeout  65;
        server {
            listen       80;
            server_name  www.liang.com;
            location /nginx_status {
       ###开启状态模块
                    stub_status on;###
            }
            location / {
                root   /var/www/html;
                index  index.html index.htm;
            }
        }
    }

## 2.2测试 ##

[root@zabbix-02 ~]# tail -1 /etc/hosts
    10.0.0.8 www.liang.com
    [root@zabbix-02 ~]# curl http://www.liang.com/nginx_status
    Active connections: 1 
    server accepts handled requests
     167 167 173 
    Reading: 0 Writing: 1 Waiting: 0

# 3.编写脚本，授权 #

## 3.1脚本内容 ##

[root@zabbix-02 ~]# cat /server/scritp/nging_monitiring.sh 
    #!/bin/bash
    Host=www.liang.com
    Port=80
    Cache_status="/server/scritp/status.txt"
    Status_message="/server/scritp/status_test.txt"
    curl http://${Host}:${Port}/nginx_status > ${Status_message} 2>/dev/null
    if [ ! -f "$Cache_status" ];then
            cat "$Status_message" > $Cache_status  2>/dev/null
    fi
    Status_time=`stat -c %Y $Cache_status`
    Date=`date +%s`
    if [ `expr $Date - $Status_time` -gt 60 ];then
            > $Cache_status
            cat $Status_message > $Cache_status 2>/dev/null
    fi
    nginx_active(){
            grep -i "active" $Cache_status|awk '{print $NF}'
    }
    
    nginx_reading(){
            grep -i "Reading" $Cache_status|awk '{print $2}'
    }
    nginx_writing(){
            grep -i "Writing" $Cache_status|awk '{print $4}'
    }
    nginx_waiting(){
            grep -i "Waiting" $Cache_status|awk '{print $NF}'
    }
    nginx_accepts(){
            awk 'NR==3{print $1}' $Cache_status
    }
    nginx_handled(){
            awk 'NR==3{print $2}' $Cache_status
    }
    nginx_requests(){
            awk 'NR==3{print $3}' $Cache_status
    }
    $1

## 3.2对脚本及文件授权 ##

[root@zabbix-02 ~]# chown -R zabbix:zabbix /server/

# 4.自定义key #

[root@zabbix-02 ~]# cat -n /etc/zabbix/zabbix_agentd.d/nginx_monitoring.conf 
         1  UserParameter=nginx_monitoring[*],bash  /server/scritp/nging_monitiring.sh $1
    [root@zabbix-02 ~]# systemctl restart zabbix-agent

# 5.zabbix-server测试 #

[root@zabbix ~]# for i in requests handled accepts waiting writing reading active ;do zabbix_get -s 10.0.0.8 -k nginx_monitoring[nginx_${i}];done
