Zabbix监控Nginx

在添加监控之前，必须要强调的是，Nginx必须支持stub_status状态的访问，不然一切都是空谈！！！

首先zabbix监控nginx 是根据nginx的Stub Status模块,抓取Status模块所提供的数据。
如果想启用Stub Status模块，在编译nginx的时候要加上参数 
--with-http_stub_status_module例如：
./configure --user=www --group=www --prefix=/usr/local/nginx --with-http_stub_status_module--with-http_ssl_module

在Nginx配置档中添加：
     location /nginx_status {
                stub_status on;
                access_log   off;
                }

一、创建监控Nginx的key

• nginx_status_key

vim /usr/local/zabbix/etc/zabbix_agentd.conf.d/nginx_status_key

UserParameter=nginx.accepts,/usr/local/zabbix/shell/nginx_status.sh accepts 
UserParameter=nginx.handled,/usr/local/zabbix/shell/nginx_status.sh handled 
UserParameter=nginx.requests,/usr/local/zabbix/shell/nginx_status.sh requests 
UserParameter=nginx.connections.active,/usr/local/zabbix/shell/nginx_status.sh active 
UserParameter=nginx.connections.reading,/usr/local/zabbix/shell/nginx_status.sh reading 
UserParameter=nginx.connections.writing,/usr/local/zabbix/shell/nginx_status.sh writing 
UserParameter=nginx.connections.waiting,/usr/local/zabbix/shell/nginx_status.sh waiting

二、创建监控Nginx的脚本(记得加执行权限)

• nginx_status.sh

vim /usr/local/zabbix/shell/nginx_status.sh

#!/bin/bash 
# Script to fetch nginx statuses for tribily monitoring systems 
# License: GPLv4 
# Set Variables 
BKUP_DATE=`/bin/date +%Y%m%d` 
LOG="/usr/local/zabbix/logs/nginx_status.log"HOST="192.168.0.217"        #HOST非常重要，确保CURL能访问到这个IP地址的Status
PORT="80"# Functions to return nginx stats 
functionactive {    /usr/bin/curl "http://$HOST:$PORT/nginx_status"2>/dev/null| grep 'Active' | awk '{print $NF}'    }     
functionreading {    /usr/bin/curl "http://$HOST:$PORT/nginx_status"2>/dev/null| grep 'Reading' | awk '{print $2}'    }     
functionwriting {    /usr/bin/curl "http://$HOST:$PORT/nginx_status"2>/dev/null| grep 'Writing' | awk '{print $4}'    }     
functionwaiting {    /usr/bin/curl "http://$HOST:$PORT/nginx_status"2>/dev/null| grep 'Waiting' | awk '{print $6}'    }     
functionaccepts {    /usr/bin/curl "http://$HOST:$PORT/nginx_status"2>/dev/null| awk NR==3 | awk '{print $1}'    }     
functionhandled {    /usr/bin/curl "http://$HOST:$PORT/nginx_status"2>/dev/null| awk NR==3 | awk '{print $2}'    }       
functionrequests {    /usr/bin/curl "http://$HOST:$PORT/nginx_status"2>/dev/null| awk NR==3 | awk '{print $3}'    } 
# Run the requested function$1

三、在Zabbix Web界面中创建Templates App Nginx模版
(1)、先创建三个item，这个store value要求是每秒变化的

• nginx.accepts
• nginx.handled
• nginx.requests

我在这边做一个示例：
模版中添加一个nginx.accepts的item

Name                nginx.accepts  
Type                Zabbix agent
Key                 nginx.accepts
Typeof information Numeric (unsigned)
Data Type           Decimal
Units               空
Store value         Detal (speed per second)
Show  value         As is

(2)、而后四个item Store value是不变的

• nginx.connections.active
• nginx.connections.reading
• nginx.connections.writing
• nginx.connections.waiting

Name                nginx.connections.active
Type                Zabbix agent
Key                 nginx.accepts
Typeof information Numeric (unsigned)
Data Type           Decimal
Units               空
Store value         As is
Show  value         As is

创建完大概是这个样子，相信新手也能做出来！！！

四、现在点击要Tempates的Graphs，分别创建两个Graphs

监控Nginx(nginx.accepts、nginx.handled、nginx.requests)
监控Nginx(nginx.connections.active、nginx.connections.reading、nginx.connections.writing、nginx.connections.waiting)

图像1：暂且取名为 Nginx_Interactive

图像2：暂且取名为 Nginx_Connection

五、Hosts-Templates-将刚才创建的Templates App Nginx链接到主机上面
完成之后大概是这个样子

六、在Screen中创建监控Nginx的Screen，将前面创建的两个图像添加进去

七、这时候在Zabbix Web页面中查看Nginx状态就OK~~~
