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
