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
