# 1.修改php配置文件
[root@web01 ~]# vim /etc/php-fpm.d/www.conf
pm.status_path = /php_status

# 2.修改nginx配置文件
[root@web01 conf.d]# vim webapp.conf
server{
			listen 80;
			server_name _;
			location / {
			root /code/webapp;
			index index.html;
}
location /status {
			stub_status on;
}
location ~ ^/(php_status)$ {
			include fastcgi_params;
			fastcgi_pass 127.0.0.1:9000;
			fastcgi_param SCRIPT_FILENAME
			$document_root$fastcgi_script_name;
}
}
# 3.重启nginx和php
[root@web01 conf.d]# systemctl restart nginx php-fpm

pool: www

#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。

监控JAVA进程JVM

在Zabbix中，JMX监控数据的获取由专门的代理程序来实现,即Zabbix-Java-Gateway来负责数据的采 集，Zabbix-Java-Gateway和JMX的Java程序之间通信获取数据

JMX在Zabbix中的运行流程

1.Zabbix-Server找Zabbix-Java-Gateway获取Java数据
2.Zabbix-Java-Gateway找Java程序(zabbix-agent)获取数据
3.Java程序返回数据给Zabbix-Java-Gateway
4.Zabbix-Java-Gateway返回数据给Zabbix-Server
5.Zabbix-Server进行数据展示
