ZABBIX 3.4 监控Nginx 状态(七）

一、环境准备

1、在nginx的配置文件中，添加status配置
        location /nginx_status {
               stub_status on;
               access_log off;
               allow 127.0.0.1;
               allow 172.17.19.19;   //zabbix服务器的IP地址，一般是内网地址 
               deny all;
       }

     //在虚拟主机 server {} 中加入上面配置，也可以单独定义一个专门用于监控的虚拟主机。
     //deny all , 拒绝除 allow 中的主机之外所有主机访问此 URL ，实现过程中如果遇到 403 ，有可能是你把自己测试的机器拒绝了

2、访问设置好的nginx-status链接，如图所示：

3、nginx Status 详细说明：

Activeconnections:对后端发起的活动连接数；

server accepts 66：nginx 总共处理了66个连接；

handled：成功创建了66次握手；

requests：总共处理了66请求。

Reading：nginx读取客户端的header数；

Writing: nginx 返回给客户端的header数；

Waiting: nginx 请求处理完成，正在等待下一请求指令的连接。

  在访问效率很高，请求很快被处理完毕的情况下，Waiting 数比较多是正常的。如果 reading + writing 数较多，则说明并发访问量很大，正在处理过程中

二、监控脚本编写

1、编写脚本，放于 /etc/zabbix/zabbix_agentd.d/目录下

#!/bin/bash
#Script to fetch nginx statuses for monitoring systems
#Author Tony 
    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

       赋予脚本执行权限：

[root@Node1 zabbix_agentd.d]# chmod a+x nginx_status.sh  //赋予执行权限
[root@Node1 zabbix_agentd.d]# ll nginx_status.sh
-rwxr-xr-x 1 root root 1157 Jan 18 15:45 nginx_status.sh

2、添加zabbix配置文件，放于 /etc/zabbix/zabbix_agentd.d/目录下（agent的配置文件 /etc/zabbix/zabbix_agentd.conf 中定义了其他key的包含目录）创建配置文件nginx_status.conf

[root@Node1 zabbix_agentd.d]# cat nginx_status.conf
UserParameter=nginx.status[*],/etc/zabbix/zabbix_agentd.d/nginx_status.sh $1

3、确保配置Agent配置文件开启自定义参数UnsafeUserParameters=1

[root@Node1 zabbix_agentd.d]# !grep
grep -n '^[a-Z]' /etc/zabbix/zabbix_agentd.conf
13:PidFile=/var/run/zabbix/zabbix_agentd.pid
32:LogFile=/var/log/zabbix/zabbix_agentd.log
43:LogFileSize=0
57:DebugLevel=3
97:Server=172.17.21.208
138:ServerActive=172.17.21.208
149:Hostname=Node1.contoso.com
267:Include=/etc/zabbix/zabbix_agentd.d/*.conf
286:UnsafeUserParameters=1    //1代表允许，0代表关闭

4、重启zabbix-agent服务

[root@Node1 ~]# systemctl restart zabbix-agent.service 

 5、在zabbix servere服务器上测试,是否能正常获取数据

[root@Node3 zabbix3.4.5]# zabbix_get -s 172.17.21.206 -p 10050 -k nginx.status[ping]   
1
[root@Node3 zabbix3.4.5]# zabbix_get -s 172.17.21.206 -p 10050 -k nginx.status[accepts]
306
[root@Node3 zabbix3.4.5]# zabbix_get -s 172.17.21.206 -p 10050 -k nginx.status[handled]
307
[root@Node3 zabbix3.4.5]# zabbix_get -s 172.17.21.206 -p 10050 -k nginx.status[requests]
311
[root@Node3 zabbix3.4.5]#

三、WEB界面配置

1、创建模板：Configuration-->Templates-->Greate template，创建模板名称：Template App NGINX，单击Add即可

2、给模板依次添加相应Item、Trigger、Graphs,如下图所示

3、关联模板，Configuration-->Hosts-->Node1--Templates，选择模板,点击Updtae即可

4、查看Nginx状态：Monitoring-->Graphs-->Host(Node1)-->Grahp(nginx status connections与nginx status server)

   备注：若相关数据比较小的话，可以使用ab进行简单压测，然后再看数值变化

[root@Node1 zabbix_agentd.d]# ab -n 10000 -c 1000 http://Node1.contoso.com/ 

 附模板：Template_Nginx_Status.xml
