php-status监控流程

1.开启php的状态页功能

#基于php-fpm进程做的实验

yum install php-fpm -y

修改配置文件，开启php，status功能即可，打开如下参数即可
要求你访问php状态页面的入口就是/status_php

[root@web-7 ~]#grep 'status_'  /etc/php-fpm.d/www.conf 
pm.status_path = /status_php

php-fpm，nginx转发过去的

设置nginx转发

[root@web-7 /etc/nginx/conf.d]#cat status.conf 
server{

listen 80;
server_name localhost;
location /nginx_status {
stub_status on;
access_log off;
}


location /php_status {
    fastcgi_pass 127.0.0.1:9000;
    fastcgi_index index.php;
    fastcgi_param SCRIPT_FILENAME html$fastcgi_script_name;
    include fastcgi_params;

}


}

重启nginx，和php-fpm俩进程

[root@web-7 ~]#systemctl restart php-fpm.service nginx.service

访问测试php_status

字段解释

[root@web-7 /etc/nginx/conf.d]#curl 127.0.0.1/php_status
pool:                 www
process manager:      dynamic
start time:           04/Jul/2022:17:27:43 +0800
start since:          158
accepted conn:        2
listen queue:         0
max listen queue:     0
listen queue len:     128
idle processes:       4
active processes:     1
total processes:      5
max active processes: 1
max children reached: 0
slow requests:        0
[root@web-7 /etc/nginx/conf.d]#


pool – fpm池子名称，大多数为www
process manager – 进程管理方式,值：static, dynamic or ondemand. dynamic
start time – 启动日期,如果reload了php-fpm，时间会更新
start since – 运行时长
accepted conn – 当前池子接受的请求数
listen queue – 请求等待队列，如果这个值不为0，那么要增加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启动开始算）
max children reached - 大道进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太小了，请改大一点。
slow requests – 启用了php-fpm slow-log，缓慢请求的数量

自定义的key php_status[采集的关键字]

UserParameter=php_status[*],/etc/zabbix/zabbix_agentd.d/php_status.sh  $1

写脚本简单的监控php-fpm状态值的脚本

#!/bin/bash
# 这是一个简单的监控php-fpm状态值的脚本

改权限

[root@web-7 /etc/zabbix/zabbix_agentd.d]#chmod +x php_status.sh 
[root@web-7 /etc/zabbix/zabbix_agentd.d]#chown -R zabbix.zabbix ./*
[root@web-7 /etc/zabbix/zabbix_agentd.d]#ll
total 20
-rw-r--r-- 1 zabbix zabbix   87 Jul  4 13:44 nginx_status.conf
-rwxr-xr-x 1 zabbix zabbix 1706 Jul  4 13:51 nginx_status.sh
-rwxr-xr-x 1 zabbix zabbix 1095 Jul  4 17:33 php_status.sh
-rw-r--r-- 1 zabbix zabbix   52 Jun 29 19:06 tcp_status.conf
-rw-r--r-- 1 zabbix zabbix 1531 Jul 29  2019 userparameter_mysql.conf

3. 重启agent
[root@web-7 /etc/zabbix/zabbix_agentd.d]#systemctl restart zabbix-agent.service 

4.手动zabbix_get测数据
[root@zabbix-server-71 ~]#zabbix_get -s 10.0.0.7 -k php_status[total_processes]
