教你用php-fpm的status查看详细信息

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poolphp-fpm pool的名称，大多数情况下为wwwprocess manager进程管理方式，现今大多都为dynamic，不要使用staticstart timephp-fpm上次启动的时间start sincephp-fpm已运行了多少秒accepted connpool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
