Zabbix 监控 Nginx

Zabbix监控Nginx

首先，大家如果看到有什么不懂的地方，欢迎吐槽！！！
我会在当天或者第二天及时回复，并且改进~~

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=nginx --group=nginx --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_keyUserParameter=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StatusPORT="80" # Functions to return nginx stats 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}'     } # 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itemName                nginx.accepts  Type                Zabbix agentKey                 nginx.acceptsType of information Numeric (unsigned)Data Type           DecimalUnits               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.activeType                Zabbix agentKey                 nginx.acceptsType of information Numeric (unsigned)Data Type           DecimalUnits               空Store value         As isShow  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~~~
