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 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 $fastcgi_script_name; } } server { listen *:80 default_server; server_name _; location ~ ^/(status|ping)$ { 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 # 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 # 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} # 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 <?xml version="1.0" ?> <status> <pool>www</pool> <process-manager>dynamic</process-manager> <start-time>1400078415</start-time> <start-since>59640</start-since> <accepted-conn>36</accepted-conn> <listen-queue>0</listen-queue> <max-listen-queue>8</max-listen-queue> <listen-queue-len>0</listen-queue-len> <idle-processes>2</idle-processes> <active-processes>1</active-processes> <total-processes>3</total-processes> <max-active-processes>5</max-active-processes> <max-children-reached>0</max-children-reached> <slow-requests>2145</slow-requests> # curl http://127.0.0.1/status?xml <?xml version="1.0" ?> <status> <pool>www</pool> <process-manager>dynamic</process-manager> <start-time>1400078415</start-time> <start-since>59640</start-since> <accepted-conn>36</accepted-conn> <listen-queue>0</listen-queue> <max-listen-queue>8</max-listen-queue> <listen-queue-len>0</listen-queue-len> <idle-processes>2</idle-processes> <active-processes>1</active-processes> <total-processes>3</total-processes> <max-active-processes>5</max-active-processes> <max-children-reached>0</max-children-reached> <slow-requests>2145</slow-requests> 6.3 html # curl http://127.0.0.1/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>dynamic</td></tr> <tr><th>start time</th><td>14/May/2014:22:40:15 +0800</td></tr> <tr><th>start since</th><td>59662</td></tr> <tr><th>accepted conn</th><td>8</td></tr> <tr><th>listen queue</th><td>0</td></tr> <tr><th>max listen queue</th><td>8</td></tr> <tr><th>listen queue len</th><td>0</td></tr> <tr><th>idle processes</th><td>2</td></tr> <tr><th>active processes</th><td>1</td></tr> <tr><th>total processes</th><td>3</td></tr> <tr><th>max active processes</th><td>5</td></tr> <tr><th>max children reached</th><td>0</td></tr> <tr><th>slow requests</th><td>2147</td></tr> </table> </body></html> # curl http://127.0.0.1/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>dynamic</td></tr> <tr><th>start time</th><td>14/May/2014:22:40:15 +0800</td></tr> <tr><th>start since</th><td>59662</td></tr> <tr><th>accepted conn</th><td>8</td></tr> <tr><th>listen queue</th><td>0</td></tr> <tr><th>max listen queue</th><td>8</td></tr> <tr><th>listen queue len</th><td>0</td></tr> <tr><th>idle processes</th><td>2</td></tr> <tr><th>active processes</th><td>1</td></tr> <tr><th>total processes</th><td>3</td></tr> <tr><th>max active processes</th><td>5</td></tr> <tr><th>max children reached</th><td>0</td></tr> <tr><th>slow requests</th><td>2147</td></tr> </table> </body></html> 6.4 full # curl http://127.0.0.1/status?full pool: www process manager: dynamic start time: 14/May/2014:22:40:15 +0800 start since: 59695 accepted conn: 1 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: 2148 ************************ pid: 29050 state: Idle start time: 15/May/2014:15:09:32 +0800 start since: 338 requests: 62 request duration: 1025585 request method: GET request URI: /index.php content length: 0 user: -

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。
