企业级Zabbix应用监控实践–PHP-FPM [ 五 ]

实践环境

一、配置文件修改（Nginx+php）

1、PHP-FPM工作模式通常与Nginx结合使用,修改php-fpm.conf

[root@Agent ~]# vim /etc/php-fpm.d/www.conf
pm.status_path = /phpfpm_status

2.修改nginx.conf的配置文件,增加如下location访问PHP-FPM状态信息。

   location ~ ^/(phpfpm_status)$ {
        include fastcgi_params;
        fastcgi_pass    127.0.0.1:9000;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
}

3.访问测试phpfpm_status

[root@Agent ~]# curl http://127.0.0.1/phpfpm_status
pool:                 www
process manager:      dynamic
start time:           05/Jul/2016:15:30:56 +0800
start since:          409
accepted conn:        22
listen queue:         0
max listen queue:     0
listen queue len:     128
idle processes:       4
active processes:     1
total processes:      5
max active processes: 2
max children reached: 0

#PHP-FPM状态解释：
pool #fpm池名称,大多数为www
process manager #进程管理方式dynamic或者static
start time #启动日志,如果reload了fpm，时间会更新
start since #运行时间
accepted conn #当前池接受的请求数
listen queue #请求等待队列,如果这个值不为0,那么需要增加FPM的进程数量
max listen queue #请求等待队列最高的数量
listen queue len #socket等待队列长度
idle processes #空闲进程数量
active processes #活跃进程数量
total processes #总进程数量
max active processes #最大的活跃进程数量（FPM启动开始计算）
max children reached #程最大数量限制的次数，如果这个数量不为0，那说明你的最大进程数量过小,可以适当调整。

4.编写php-fpm的Shell脚本(如果端口不一致,只需要修改脚本端口即可)

[root@Agent ~]# cd /etc/zabbix/scripts
[root@Agent scripts]# vim phpfpm_status.sh
#!/bin/bash

start_since(){

}

}

}

    start_since)

        accepted_conn;

                ;;
          *)
        echo $"USAGE:$0 {start_since|accepted_conn|listen_queue|max_listen_queue|listen_queue_len|idle_processes|active_processes|total_processes|max_active_processes|max_children_reached}"
    esac

5.给脚本添加执行权限

[root@Agent scripts]# chmod +x phpfpm_status.sh

6.监控项的phpfpm_status.conf配置文件如下：

[root@Agent ~]# cat /etc/zabbix/zabbix_agentd.d/phpfpm_status.conf
UserParameter=phpfpm_status[*],/bin/bash /etc/zabbix/scripts/phpfpm_status.sh "$1"

6.重启zabbix-agent

[root@Agent ~]# systemctl restart  zabbix-agent

7.Server使用zabbix_get命令来获取Agent端的值

[root@linux-node1 zabbix_agentd.d]# zabbix_get -s 192.168.90.11 -k phpfpm_status[accepted_conn]
45

8.添加所有监控项, 如下图4-5, 最后记得关联至对应主机

9.查看图形，如下图(图形自定义)
