启用php-fpm状态详解

更新：2022-05-23 08:41:54编辑：Story归类：技术分享人气：148

php-fpm和nginx一样内建了一个状态页，对于想了解php-fpm的状态以及监控php-fpm非常有帮助。为了后续的zabbix监控，我们需要先了解php-fpm状态页是怎么回事。

1. 启用php-fpm状态功能

# cat  /usr/local/php-5.5.10/etc/php-fpm.conf | grep status_path
pm.status_path = /status

1 2	# cat /usr/local/php-5.5.10/etc/php-fpm.conf \| grep status_path pm . status_path = / status

默认情况下为/status，当然也可以改成其他的，例如/ttlsa_status等等。

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 default_server;
    server_name _;
    location ~ ^/(status|ping)$
    {
        include fastcgi_params;
        fastcgi_pass 127.0.0.1:9000;
        fastcgi_param SCRIPT_FILENAME $fastcgi_script_name;
    }
}

server {

listen * : 80 default_server ;

server _name _ ;

location ~ ^ / ( status | ping ) $

{

include fastcgi_params ;

fastcgi _pass 127.0.0.1 : 9000 ;

fastcgi_param SCRIPT _FILENAME $ fastcgi_script_name ;

}

3. 重启nginx/php-fpm
请依照你的环境重启你的nginx和php-fpm

# service nginx restart
# service php-fpm restart

1 2	# service nginx restart # service php-fpm restart

4. 打开status页面

# curl http://www.ttlsa.com/status
pool:                 www
process manager:      dynamic
start time:           14/May/2014:22:40:15 +0800
start since:          58508
accepted conn:        33
listen queue:         0
max listen queue:     8
listen queue len:     0
idle processes:       2
active processes:     1
total processes:      3
max active processes: 5
max children reached: 0
slow requests:        2091

# curl http://www.ttlsa.com/status

pool : www

process manager : dynamic

start time : 14 / May / 2014 : 22 : 40 : 15 + 0800

start since : 58508

accepted conn : 33

listen queue : 0

max listen queue : 8

listen queue len : 0

idle processes : 2

active processes : 1

total processes : 3

max active processes : 5

max children reached : 0

slow requests : 2091

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/status?json
{"pool":"www","process manager":"dynamic","start time":1400078415,"start since":59624,"accepted conn":27,"listen queue":0,"max listen queue":8,"listen queue len":0,"idle processes":2,"active processes":1,"total processes":3,"max active processes":5,"max children reached":0,"slow requests":2145}

# curl http://127.0.0.1/status?json

{ "pool" : "www" , "process manager" : "dynamic" , "start time" : 1400078415 , "start since" : 59624 , "accepted conn" : 27 , "listen queue" : 0 , "max listen queue" : 8 , "listen queue len" : 0 , "idle processes" : 2 , "active processes" : 1 , "total processes" : 3 , "max active processes" : 5 , "max children reached" : 0 , "slow requests" : 2145 }

6.2 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状态页非常使用，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。
