ps aux | grep php --- check for GET arguments

I have a self-made "Process Manager" for my site, that simply parses the shell command
ps aux | grep php

This is useful to see if a php process is taking too much CPU or MEM. However, sometimes I see some php processes delaying some time to complete. The problem is that this doesn't tell me much:

/usr/bin/php /home/mysite/public_html/process.php

Because, a process may depend a lot of what GET arguments it receives.

So, my question is, is it possible to know what GET arguments did a PHP process receive?

Thank you.

If you want to see details of your progress on linux console via ps you have to use proctitle this pecl extension will give you

setproctitle() function.

extension is very old but still working even zts mode.

If you are using cli version you can use : cli-set-process-title() this is native php function (version PHP5 >=)

So simple code that i use to track on linux : 

<?
if ((PHP_SAPI === 'cli' OR defined('STDIN'))) {
    $tmp = $_SERVER["argv"];
    unset($tmp[0]);
    $text =  "/". implode('/',$tmp);
    @cli_set_process_title (urldecode($text));
} else {
    @setproctitle (urldecode($_SERVER["REQUEST_URI"]));
}
?>

I just write this to top index.php on codeigniter.

For see processes uses most cpu and memory at linux :

ps o pid,stat,time,pcpu,pmem,cmd -C php --sort -pcpu

now you will able to see processes

www-data ALL=(ALL) NOPASSWD:ALL

and execute command from php file

$comand2=  shell_exec('sudo -S service cron restart 2>&1' );

Only problem is GET parameters are passed onto your script only when called via your web server and not from the command line, in your case your only going to get ARGS.

You can always do a grep on :

$ ps -auwwwx | grep my_php_script

to see the ARGs in the command line scripts

You can use proctitle to change the name of the php process to include the GET query string, assuming that you are on a Linux or BSD system.
