# 操作环境 #

Centos 7.2

zabbix 3.2

nginx 1.10

# 操作步骤 #

1.安装配置zabbix-server以及agent参照 [《Centos 7下搭建Zabbix监控软件》][Centos 7_Zabbix]

2.在nginx server中启动nginx status，在nginx.conf配置文件中添加以下内容

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

添加完成后，重启nginx

#systemctl restart nginx

下面来通过curl获取nginx status，并了解其参数值

[root@ovirt-host-227 ~]# curl http://127.0.0.1/nginx_status
    Active connections: 1 
    server accepts handled requests
     10942 10942 10942 
    Reading: 0 Writing: 1 Waiting: 0

active connections – 活跃的连接数量  
server accepts handled requests — 总共处理了10942个连接 , 成功创建10942次握手, 总共处理了10942个请求  
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.

3.在zabbix-agent上编辑nginx\_status.sh脚本，用于zabbix\_agent获取数据

#!/bin/bash
    
    HOST="127.0.0.1"
    PORT="80"
    
    function ping {
        /sbin/pidof nginx | wc -l
    }
    
    function active {
        /usr/bin/curl "http://$HOST:$PORT/nginx_status/" 2>/dev/null| grep 'Active' | awk '{print $NF}'
    }
    function reading {
        /usr/bin/curl "http://$HOST:$PORT/nginx_status/" 2>/dev/null| grep 'Reading' | awk '{print $2}'
    }
    function writing {
        /usr/bin/curl "http://$HOST:$PORT/nginx_status/" 2>/dev/null| grep 'Writing' | awk '{print $4}'
    }
    function waiting {
        /usr/bin/curl "http://$HOST:$PORT/nginx_status/" 2>/dev/null| grep 'Waiting' | awk '{print $6}'
    }
    function accepts {
        /usr/bin/curl "http://$HOST:$PORT/nginx_status/" 2>/dev/null| awk NR==3 | awk '{print $1}'
    }
    function handled {
        /usr/bin/curl "http://$HOST:$PORT/nginx_status/" 2>/dev/null| awk NR==3 | awk '{print $2}'
    }
    function requests {
        /usr/bin/curl "http://$HOST:$PORT/nginx_status/" 2>/dev/null| awk NR==3 | awk '{print $3}'
    }
    $1

编辑完成后，给它授权

#chmod a+x nginx_status.sh

运行该脚本进行测试，如获取requets数值

[root@ovirt-host-227 zabbix_agentd.d]# ./nginx_status.sh requests
    11032

脚本完成后，下面添加UserParameter参数至zabbix-agent配置文件中，添加以下内容

###############NGINX STATUS MONITOR#################
    
    UserParameter=nginx.status[*],/etc/zabbix/zabbix_agentd.d/nginx_status.sh $1

添加完成后，重启zabbix-agent

#systemctl restart zabbix-agent

下面我们在zabbix-server端，通过zabbix\_get来获取zabbix-agent也就是nginx server中的nginx status，如requests数值

[root@centos7-zabbix-193 ~]# zabbix_get -s 10.10.200.227 -p 10050 -k nginx.status[requests]
    11076

可以正确获取数值。

4.在zabbix web console端创建template “NGINX STATUS MONITOR”

![Center][]

创建item

根据zabbix-agent中的nginx\_status.sh的参数，总共要创建active、reading、writing、waiting、accepts、handled、requests这7项item，下面以创建accepts为例，其他创建

方法都是相同的

![Center 1][]

所有项目创建完成后如下：

![Center 2][]

item创建完成后，我们来创建graph，根据参数的不同，创建了两个graphs

![Center 3][]

![Center 4][]

以上就完成的NGINX STATUS MONTIOR Template的创建，下面将该Template添加至zabbix-agent中

![Center 5][]

添加完成后，我们查看该zabbix-agent的graphs中，已经显示了nginx的两个图形

![Center 6][]

下面查看这两个图中的内容

![Center 7][]

![Center 8][]

以上就完成后nginx status监控的所有步骤，下面的为通过上面操作步骤所创建nginx status monitorTTemplate所导出的xml模板，可以直接导入至zabbix-server中进行使用
