推荐:python 命令行参数

本篇将介绍python中sys, getopt模块处理命令行参数 如果想对python脚本传参数,python中对应的argc, argv(c语言的命令行参数)是什么呢? 需要模块:sys 参数个数

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 = /status nginx.conf 中配置: location = /status {

include

fastcgi_params;

fastcgi_param

SCRIPT_FILENAME $document_root$fastcgi_script_name;

fastcgi_index

index.php;

fastcgi_pass

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: ;

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: ;

java 命令行运行时参数包含&字符的问题: 当你通过命令行运行程序时可能参数中包含&字符,jvm就会将&截取中断后面参数。解决方法:通过编译后的字符替换&字符(如
