说明：
phpfpm跟nginx一样有个status状态监控页。可能通过status状态监控页了解phpfpm的运行状态，如并发数，总进程数等。
具体：
1. 启用php-fpm状态功能
# vim /usr/local/php/etc/php-fpm.conf | grep status_path pm.status_path = /phpfpm_status //这个要与第2步nginx上的location上一致，写成这样也是zabbix监控时与nginx的区分开来
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;
server_name 127.0.0.1;
location /phpfpm_status {
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
include fastcgi.conf;
}
}
3. 重启nginx，php-fpm
# service nginx restart # service php-fpm restart
4. 打开status页面
# curl http://127.0.0.1/phpfpm_status pool: www process manager: static start time: 30/Jan/2015:13:58:14 +0800 start since: 1186 accepted conn: 6955 listen queue: 0 max listen queue: 1 listen queue len: 0 idle processes: 159 active processes: 1 total processes: 160 max active processes: 13 max children reached: 0 slow requests: 7
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/phpfpm_status?json
{"pool":"www","process manager":"static","start time":1422597494,"start since":3033,"accepted conn":38690,"listen queue":0,"max listen queue":1,"listen queue len":0,"idle processes":159,"active processes":1,"total processes":160,"max active processes":13,"max children reached":0,"slow requests":9}
6.2 xml
# curl http://127.0.0.1/phpfpm_status?xml <?xml version="1.0" ?> <status> <pool>www</pool> <process-manager>static</process-manager> <start-time>1422597494</start-time> <start-since>3087</start-since> <accepted-conn>40297</accepted-conn> <listen-queue>0</listen-queue> <max-listen-queue>1</max-listen-queue> <listen-queue-len>0</listen-queue-len> <idle-processes>159</idle-processes> <active-processes>1</active-processes> <total-processes>160</total-processes> <max-active-processes>13</max-active-processes> <max-children-reached>0</max-children-reached> <slow-requests>9</slow-requests>
6.3 html
# curl http://127.0.0.1/phpfpm_status?html <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head><title>PHP-FPM Status Page</title></head> <body> <table> <tr><th>pool</th><td>www</td></tr> <tr><th>process manager</th><td>static</td></tr> <tr><th>start time</th><td>30/Jan/2015:13:58:14 +0800</td></tr> <tr><th>start since</th><td>3156</td></tr> <tr><th>accepted conn</th><td>41985</td></tr> <tr><th>listen queue</th><td>0</td></tr> <tr><th>max listen queue</th><td>1</td></tr> <tr><th>listen queue len</th><td>0</td></tr> <tr><th>idle processes</th><td>159</td></tr> <tr><th>active processes</th><td>1</td></tr> <tr><th>total processes</th><td>160</td></tr> <tr><th>max active processes</th><td>13</td></tr> <tr><th>max children reached</th><td>0</td></tr> <tr><th>slow requests</th><td>9</td></tr> </table> </body></html>

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状态页很实用，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。
