在浏览器里查看Nginx和PHP-FPM的运行状态
查看Nginx状态
location /nginx_status {stub_status on;
access_log off;
allow 127.0.0.1;
deny all;
}
curl http://127.0.0.1/nginx_status
http://nginx.org/en/docs/http/ngx_http_status_module.html
输出样例:
Active connections: 3
server accepts handled requests
17737 17737 49770
Reading: 0 Writing: 1 Waiting: 2
各项解释:
Active connections: 当前 Nginx 正处理的活动连接数.
server accepts handled requests: 总共处理了 17737 个连接, 成功创建 17737 次握手(证明中间没有失败的), 总共处理了 49770 个请求.
Reading: Nginx 读取到客户端的 Header 信息数.
Writing: Nginx 返回给客户端的 Header 信息数.
Waiting: 开启 keep-alive 的情况下, 这个值等于 Active - (Reading + Writing), 意思就是 Nginx 已经处理完正在等候下一次请求指令的驻留连接.
查看PHP-FPM状态
php-fpm.conf 中开启 pm.status_path = /statusnginx.conf 中配置:
location /status {
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_index index.php;
fastcgi_pass 127.0.0.1:9000;
}
访问 http://127.0.0.1/status?full 查看状态信息(我只开了一个PHP-FPM工作进程):
pool: www
process manager: static
start time: 27/Dec/2014:13:29:00 +0800
start since: 2571
accepted conn: 28
listen queue: 0
max listen queue: 0
listen queue len: 128
idle processes: 0
active processes: 1
total processes: 1
max active processes: 1
max children reached: 0
slow requests: 0
************************
pid: 1275
state: Running
start time: 27/Dec/2014:13:29:00 +0800
start since: 2571
requests: 28
request duration: 100
request method: GET
request URI: /status?full
content length: 0
user: -
script: -
last request cpu: 0.00
last request memory: 0
附: 下面是php-fpm.conf里的说明
; The URI to view the FPM status page. If this value is not set, no URI will be
; recognized as a status page. It shows the following informations:
; pool - the name of the pool;
; process manager - static, dynamic or ondemand;
; start time - the date and time FPM has started;
; start since - number of seconds since FPM has started;
; accepted conn - the number of request accepted by the pool;
; listen queue - the number of request in the queue of pending
; connections (see backlog in listen(2));
; max listen queue - the maximum number of requests in the queue
; of pending connections since FPM has started;
; listen queue len - the size of the socket queue of pending connections;
; idle processes - the number of idle processes;
; active processes - the number of active processes;
; total processes - the number of idle + active processes;
; max active processes - the maximum number of active processes since FPM
; has started;
; max children reached - number of times, the process limit has been reached,
; when pm tries to start more children (works only for
; pm ‘dynamic‘ and ‘ondemand‘);
; Value are updated in real time.
; Example output:
; pool: www
; process manager: static
; start time: 01/Jul/2011:17:53:49 +0200
; start since: 62636
; accepted conn: 190460
; listen queue: 0
; max listen queue: 1
; listen queue len: 42
; idle processes: 4
; active processes: 11
; total processes: 15
; max active processes: 12
; max children reached: 0
;
; By default the status page output is formatted as text/plain. Passing either
; ‘html‘, ‘xml‘ or ‘json‘ in the query string will return the corresponding
; output syntax. Example:
; http://www.foo.bar/status
; http://www.foo.bar/status?json
; http://www.foo.bar/status?html
; http://www.foo.bar/status?xml
;
; By default the status page only outputs short status. Passing ‘full‘ in the
; query string will also return status for each pool process.
; Example:
; http://www.foo.bar/status?full
; http://www.foo.bar/status?json&full
; http://www.foo.bar/status?html&full
; http://www.foo.bar/status?xml&full
; The Full status returns for each process:
; pid - the PID of the process;
; state - the state of the process (Idle, Running, ...);
; start time - the date and time the process has started;
; start since - the number of seconds since the process has started;
; requests - the number of requests the process has served;
; request duration - the duration in μs of the requests;
; request method - the request method (GET, POST, ...);
; request URI - the request URI with the query string;
; content length - the content length of the request (only with POST);
; user - the user (PHP_AUTH_USER) (or ‘-‘ if not set);
; script - the main script called (or ‘-‘ if not set);
; last request cpu - the %cpu the last request consumed
; it‘s always 0 if the process is not in Idle state
; because CPU calculation is done when the request
; processing has terminated;
; last request memory - the max amount of memory the last request consumed
; it‘s always 0 if the process is not in Idle state
; because memory calculation is done when the request
; processing has terminated;
; If the process is in Idle state, then informations are related to the
; last request the process has served. Otherwise informations are related to
; the current request being served.
; Example output:
; ************************
; pid: 31330
; state: Running
; start time: 01/Jul/2011:17:53:49 +0200
; start since: 63087
; requests: 12808
; request duration: 1250261
; request method: GET
; request URI: /test_mem.php?N=10000
; content length: 0
; user: -
; script: /home/fat/web/docs/php/test_mem.php
; last request cpu: 0.00
; last request memory: 0
;
; Note: There is a real-time FPM status monitoring sample web page available
; It‘s available in: ${prefix}/share/fpm/status.html
;
; Note: The value must start with a leading slash (/). The value can be
; anything, but it may not be a good idea to use the .php extension or it
; may conflict with a real PHP file.
; Default Value: not set
; pm.status_path = /status
