启用php-fpm状态详解

2017-02-23 13:44 405 查看
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

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;
}
}
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

4. 打开status页面

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

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。
