phpfpm使用自带的status优化步骤-php教程-PHP中文网

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

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

2. nginx配置

<code>server {
    listen  *:<span>80</span> default_server;
    server_name _;
    location ~ ^/(status|ping)$
    {
        <span><strong>include</strong></span> fastcgi_params;
        fastcgi_pass <span>127.0</span><span>.0</span><span>.1</span>:<span>9000</span>;
        fastcgi_param SCRIPT_FILENAME <span>$fastcgi_script_name</span>;
    }
}</code>

3. 重启nginx/php-fpm

<code>service nginx restart
service php<span>-fpm</span> restart</code>

登录后复制

4. 打开status页面

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

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<strong>队列</strong>，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

<code># curl http://<span>127.0</span><span>.0</span><span>.1</span>/status?json
{"<span>pool</span>":<span><span>"www"</span></span>,"<span>process manager</span>":<span><span>"dynamic"</span></span>,"<span>start time</span>":<span><span>1400078415</span></span>,"<span>start since</span>":<span><span>59624</span></span>,"<span>accepted conn</span>":<span><span>27</span></span>,"<span>listen queue</span>":<span><span>0</span></span>,"<span>max listen queue</span>":<span><span>8</span></span>,"<span>listen queue len</span>":<span><span>0</span></span>,"<span>idle processes</span>":<span><span>2</span></span>,"<span>active processes</span>":<span><span>1</span></span>,"<span>total processes</span>":<span><span>3</span></span>,"<span>max active processes</span>":<span><span>5</span></span>,"<span>max children reached</span>":<span><span>0</span></span>,"<span>slow requests</span>":<span><span>2145</span></span>}</code>

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）
