服务监控：PHP-FPM状态监控

1.配置所有Agent(标准化目录结构)

[root@linux-node1 ~]# vim /etc/zabbix/zabbix_agentd.conf #编辑配置文件引用key
Include=/etc/zabbix/zabbix_agentd.d/*.conf
[root@linux-node1 ~]# mkdir /etc/zabbix/scripts #存放Shell脚本

2.PHP-FPM工作模式通常与Nginx结合使用,修改php-fpm.conf(找到自己的php-fpm.conf存放路径)

[root@linux-node1 ~]# vim /etc/php-fpm.d/www.conf #我php-fpm存放路径
pm.status_path = /phpfpm_status

3.修改nginx.conf的配置文件,通过Nginx访问PHP-FPM状态。

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

4.访问测试phpfpm_status

[root@linux-node4 conf.d]# 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@linux-node1 ~]# cd /etc/zabbix/scripts
[root@linux-node1 scripts]# vim phpfpm_status.sh
#!/bin/bash
PHPFPM_COMMAND=$1
PHPFPM_PORT=80 #根据监听不同端口进行调整
start_since(){
/usr/bin/curl -s "http://127.0.0.1:"$PHPFPM_PORT"/phpfpm_status" |awk '/^start since:/ {print $NF}'
}
accepted_conn(){
/usr/bin/curl -s "http://127.0.0.1:"$PHPFPM_PORT"/phpfpm_status" |awk '/^accepted conn:/ {print $NF}'
}
listen_queue(){
/usr/bin/curl -s "http://127.0.0.1:"$PHPFPM_PORT"/phpfpm_status" |awk '/^listen queue:/ {print $NF}'
}
max_listen_queue(){
/usr/bin/curl -s "http://127.0.0.1:"$PHPFPM_PORT"/phpfpm_status" |awk '/^max listen queue:/ {print $NF}'
}
listen_queue_len(){
/usr/bin/curl -s "http://127.0.0.1:"$PHPFPM_PORT"/phpfpm_status" |awk '/^listen queue len:/ {print $NF}'
}
idle_processes(){
/usr/bin/curl -s "http://127.0.0.1:"$PHPFPM_PORT"/phpfpm_status" |awk '/^idle processes:/ {print $NF}'
}
active_processes(){
/usr/bin/curl -s "http://127.0.0.1:"$PHPFPM_PORT"/phpfpm_status" |awk '/^active processes:/ {print $NF}'
}
total_processes(){
/usr/bin/curl -s "http://127.0.0.1:"$PHPFPM_PORT"/phpfpm_status" |awk '/^total processes:/ {print $NF}'
}
max_active_processes(){
/usr/bin/curl -s "http://127.0.0.1:"$PHPFPM_PORT"/phpfpm_status" |awk '/^max active processes:/ {print $NF}'
}
max_children_reached(){
/usr/bin/curl -s "http://127.0.0.1:"$PHPFPM_PORT"/phpfpm_status" |awk '/^max children reached:/ {print $NF}'
}
slow_requests(){
/usr/bin/curl -s "http://127.0.0.1:"$PHPFPM_PORT"/phpfpm_status" |awk '/^slow requests:/ {print $NF}'
}
case $PHPFPM_COMMAND in

*)
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

给脚本添加执行权限

[root@linux-node1 scripts]# chmod +x phpfpm_status.sh

5.key的phpfpm_status.conf的子配置文件如下：

[root@linux-node1 ~]# 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@linux-node1 ~]# systemctl restart zabbix-agent

7.测试一定使用Zabbix_get来获取值

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

8.展示所有Key(记得将模板关联主机)如图4-5 

9.查看图形，如图4-4(图形自定义)
