phpfpm使用自带的status优化步骤

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

2. nginx配置

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

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

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}

• 6.2 xml

# curl http://127.0.0.1/status?xml
status>
