php-fpm的status可以查看汇总信息和详细信息
nginx.conf 配置文件
server {
listen 80;
server_name localhost;
index index.php index.html;
root /home/tinywan/zabbix;
location / {
try_files $uri $uri/ /index.php?$args;
}
location ~ \.php$ {
fastcgi_pass unix:/var/run/php7.0.9-fpm.sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
location /nginx_status {
stub_status on;
access_log off;
allow 127.0.0.1;
##allow 192.168.249.0/24;
deny all;
}
location ~ /php_fpm-status$ {
allow 127.0.0.1;
#deny all;
fastcgi_param SCRIPT_FILENAME $fastcgi_script_name;
include fastcgi_params;
fastcgi_pass unix:/var/run/php7.0.9-fpm.sock;
}
}
启用php-fpm状态功能
tinywan@tinywan:/opt/php-7.0.9$ cat /opt/php-7.0.9/etc/php-fpm.d/www.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。
vim /opt/php-7.0.9/etc/php-fpm.d/www.conf pm.status_path = /php_fpm-status #去掉了前面的;注释符，并更名为php_fpm-status
修改完php-fpm.conf后，使用service php-fpm reload重新加载配置文件
tinywan@tinywan:/opt/php-7.0.9$ sudo /opt/php-7.0.9/sbin/php-fpm tinywan@tinywan:/opt/php-7.0.9$ ps -aux | grep php-fpm root 2769 4.1 0.1 212532 14676 ? Ss 09:50 0:00 php-fpm: master process (/opt/php-7.0.9/etc/php-fpm.conf) tinywan 2770 3.2 0.1 212532 11084 ? S 09:50 0:00 php-fpm: pool www tinywan 2771 5.9 0.1 212532 11084 ? S 09:50 0:00 php-fpm: pool www tinywan 2773 0.0 0.0 15984 944 pts/21 S+ 09:50 0:00 grep --color=auto php-fpm
使用curl指令查看php-fpm的status
tinywan@tinywan:/usr/local/nginx$ curl localhost/php_fpm-status pool: www process manager: dynamic start time: 13/May/2017:09:50:43 +0800 start since: 986 accepted conn: 2 listen queue: 0 max listen queue: 0 listen queue len: 0 idle processes: 1 active processes: 1 total processes: 2 max active processes: 1 max children reached: 0 slow requests: 0
php-fpm的status可以查看汇总信息和详细信息，详细信息比汇总信息要多出每一个php-fpm进程的相关信息，同时支持多种格式输出，如xml、html和json，默认情况下分别使用如果指令即可：
json格式
tinywan@tinywan:~$ curl localhost/php_fpm-status?json
{"pool":"www","process manager":"dynamic","start time":1494640243,
"start since":1609,"accepted conn":13,"listen queue":0,"max listen queue":0,
"listen queue len":0,"idle processes":1,"active processes":1,"total processes":2,
"max active processes":1,"max children reached":0,"slow requests":0}
xml格式
tinywan@tinywan:~$ curl localhost/php_fpm-status?xml <?xml version="1.0" ?> <status> <pool>www</pool> <process-manager>dynamic</process-manager> <start-time>1494640243</start-time> <start-since>1692</start-since> <accepted-conn>15</accepted-conn> <listen-queue>0</listen-queue> <max-listen-queue>0</max-listen-queue> <listen-queue-len>0</listen-queue-len> <idle-processes>1</idle-processes> <active-processes>1</active-processes> <total-processes>2</total-processes> <max-active-processes>1</max-active-processes> <max-children-reached>0</max-children-reached> <slow-requests>0</slow-requests> </status>
所有格式：
Examples for summary status page: http://127.0.0.1/php_fpm-status http://127.0.0.1/php_fpm-status?json http://127.0.0.1/php_fpm-status?html http://127.0.0.1/php_fpm-status?xml Example for detailed status page: http://127.0.0.1/php_fpm-status?full http://127.0.0.1/php_fpm-status?json&full http://127.0.0.1/php_fpm-status?html&full http://127.0.0.1/php_fpm-status?xml&full

php-fpm status的含义
| 字段 | 含义 |
|---|---|
| pool | php-fpm pool的名称，大多数情况下为www |
| process manager | 进程管理方式，现今大多都为dynamic，不要使用static |
| start time | php-fpm上次启动的时间 |
| start since | php-fpm已运行了多少秒 |
| accepted conn | pool接收到的请求数 |
| listen queue | 处于等待状态中的连接数，如果不为0，需要增加php-fpm进程数 |
| max listen queue | 从php-fpm启动到现在处于等待连接的最大数量 |
| listen queue len | 处于等待连接队列的套接字大小 |
| idle processes | 处于空闲状态的进程数 |
| active processes | 处于活动状态的进程数 |
| total processess | 进程总数 |
| max active process | 从php-fpm启动到现在最多有几个进程处于活动状态 |
| max children reached | 当pm试图启动更多的children进程时，却达到了进程数的限制，达到一次记录一次，如果不为0，需要增加php-fpm pool进程的最大数 |
| slow requests | 当启用了php-fpm slow-log功能时，如果出现php-fpm慢请求这个计数器会增加，一般不当的Mysql查询会触发这个值 |
