Zabbix monitors Nginx

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！！！

<code>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 
<span>--</span><span>with</span><span>-http_stub_status_module</span>例如：
<span>.</span>/configure <span>--</span>user<span>=</span>www <span>--</span><span>group</span><span>=</span>www <span>--</span>prefix<span>=</span>/usr/<span>local</span>/nginx <span>--</span><span>with</span><span>-http_stub_status_module</span><span>--</span><span>with</span><span>-http_ssl_module</span></code>

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

一、创建监控Nginx的key

• nginx_status_key

<code>vim /usr/local/zabbix/etc/zabbix_agentd<span>.conf</span><span>.d</span>/nginx_status_key

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

---

二、创建监控Nginx的脚本(记得加执行权限)

• nginx_status.sh

<code>vim /usr/local/zabbix/shell/nginx_status.sh

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

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

<code>我在这边做一个示例：
模版中添加一个nginx.accepts的item

Name                nginx.accepts  
<span>Type</span>                Zabbix agent
Key                 nginx.accepts
<span>Type</span><span>of</span> information Numeric (<span>unsigned</span>)
Data <span>Type</span>           Decimal
<span>Units</span>               空
Store value         Detal (speed per second)
Show  value         As <span>is</span></code>

(2)、而后四个item Store value是不变的

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

<code>Name                nginx.connections.active
<span>Type</span>                Zabbix agent
Key                 nginx.accepts
<span>Type</span><span>of</span> information Numeric (<span>unsigned</span>)
Data <span>Type</span>           Decimal
<span>Units</span>               空
Store value         As <span>is</span>
Show  value         As <span>is</span></code>

---

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

<code>监控Nginx(nginx<span>.accepts</span>、nginx<span>.handled</span>、nginx<span>.requests</span>)
监控Nginx(nginx<span>.connections</span><span>.active</span>、nginx<span>.connections</span><span>.reading</span>、nginx<span>.connections</span><span>.writing</span>、nginx<span>.connections</span><span>.waiting</span>)</code>

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~~~
