phpfpm status状态说明

说明：
phpfpm跟nginx一样有个status状态监控页。可能通过status状态监控页了解phpfpm的运行状态，如并发数，总进程数等。

具体：
1. 启用php-fpm状态功能

# vim /usr/local/php/etc/php-fpm.conf | grep status_path
pm.status_path = /phpfpm_status  //这个要与第2步nginx上的location上一致，写成这样也是zabbix监控时与nginx的区分开来

 
2. nginx配置
在默认主机里面加上location或者你希望能访问到的主机里面。

server {
    listen  80;
    server_name 127.0.0.1;
    location /phpfpm_status {
                fastcgi_pass   127.0.0.1:9000;
                fastcgi_index  index.php;
                include fastcgi.conf;
    }
}

 
3. 重启nginx，php-fpm

# service nginx restart
# service php-fpm restart

 
4. 打开status页面

# curl http://127.0.0.1/phpfpm_status
pool:                 www
process manager:      static
start time:           30/Jan/2015:13:58:14 +0800
start since:          1186
accepted conn:        6955
listen queue:         0
max listen queue:     1
listen queue len:     0
idle processes:       159
active processes:     1
total processes:      160
max active processes: 13
max children reached: 0
slow requests:        7

 
5. php-fpm status详解

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

 
6. php-fpm其他参数
php-fpm状态页比较个性化的一个地方是它可以带参数，可以带参数json、xml、html并且前面三个参数可以分别和full做一个组合。

6.1 json

# curl http://127.0.0.1/phpfpm_status?json
{"pool":"www","process manager":"static","start time":1422597494,"start since":3033,"accepted conn":38690,"listen queue":0,"max listen queue":1,"listen queue len":0,"idle processes":159,"active processes":1,"total processes":160,"max active processes":13,"max children reached":0,"slow requests":9}

 
6.2 xml

# curl http://127.0.0.1/phpfpm_status?xml

6.5 full详解

pid – 进程PID，可以单独kill这个进程. You can use this PID to kill a long running process.
state – 当前进程的状态 (Idle, Running, …)
start time – 进程启动的日期
start since – 当前进程运行时长
requests – 当前进程处理了多少个请求
request duration – 请求时长（微妙）
request method – 请求方法 (GET, POST, …)
request URI – 请求URI
content length – 请求内容长度 (仅用于 POST)
user – 用户 (PHP_AUTH_USER) (or ‘-’ 如果没设置)
script – PHP脚本 (or ‘-’ if not set)
last request cpu – 最后一个请求CPU使用率。
last request memorythe – 上一个请求使用的内存

 
7. 完成
php-fpm状态页很实用，使用zabbix或者nagios监控可以考虑使用xml或者默认方式。用web的话，推荐使用html，表格会比较清晰。
