启用php-fpm状态详解

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 12 # cat  /usr/local/php-5.5.10/etc/php-fpm.conf | grep status_pathpm.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 $fastcgi_script_name;     } } 12345678910 server {    listen  *:80 default_server;    server_name _;    location ~ ^/(status|ping)$    {        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 12 # 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 123456789101112131415 # curl http://www.ttlsa.com/statuspool:                 wwwprocess manager:      dynamicstart time:           14/May/2014:22:40:15 +0800start since:          58508accepted conn:        33listen queue:         0max listen queue:     8listen queue len:     0idle processes:       2active processes:     1total processes:      3max active processes: 5max children reached: 0slow 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} 12 # 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。
