Scan the machine/server using php

Question

I am creating a system report, I honestly did not know that PHP did this, I researched and I found that I did, but I found no useful explanation, I just found PHP SYS INFO as a reference.

When I say machine I mean = server/pc/machine where the system is running

My points of doubt, follow this listing..

1. Address Information -> Server IP, Host Name
2. System -> Last boot, active for how long, active and inactive processes, CPU and SYS temperature'
3. Use of Memory -> How much of the total is used

if there is any article, or guidance to get this thank you.

Answer 1

There is an interesting project on Github that allows us to get a "universe" of information about the system:

phpsysinfo

A great advantage is the support we get because the project is tested in numerous platforms:

• Linux 2.6.x
• Freebsd 7.x
• Openbsd 2.8+
• Netbsd
• Dragonfly
• IBM AIX
• HP-UX
• Darwin/OSX
• Win 2000 / Win 2003 / Win XP / Win Vista / Win 7 / Win 8 / Win 8.1
• > PHP 5.2 or later With PCRE, XML, XSL, Mbstring and Simplexml Extension.

Installation

The installation process is relatively simple but lacks two points of attention described below along with the installation notes:

1. Unzip the source code that can be discharged here to the server root.

2. In the folder there is a configuration file called phpsysinfo.ini.new, if the installation being done is a new installation, you should copy this file to phpsysinfo.ini and edit it:

   cp phpsysinfo.ini.new phpsysinfo.ini
   

3. Perform the following checks on file php.ini server:

   • Check whether the input include_path contains .

   • Because phpsysinfo requires access to many files on /proc among others, it is important to have the safe_mode deactivated:

     For this purpose in the archive php.ini, change the line of safe_mode for:

     safe_mode = Off
     

   Finally, ensure that the PHP extension with the name is installed php-xml, the same is necessary for the proper functioning of phpsysinfo.

If file changes have been made php.ini, just restart the server and ready, the fun can begin.

Note: To locate the file php.ini on the server, from the command line we can use the following command:

find / -name php.ini -print

Demonstration

There is a multi-language online demonstration that demonstrates the numerous potentialities of this project:

http://phpsysinfo.sourceforge.net/phpsysinfo/index.php?disp=dynamic

^{And much more...}

Data format

Data can also be extracted through the API in the format that fits what we want to do:

• XML ^{see example}

  /phpsysinfo/xml.php?plugin=complete
  

• JSON ^{see example}

  /phpsysinfo/xml.php?plugin=complete&json
  

• JSONP ^{see example}

  /phpsysinfo/xml.php?plugin=complete&jsonp&callback=getData

Considering that your PHP server is Linux (hardly has PHP installation on Windows), how to get the information you want:

• IP: $_SERVER['SERVER_ADDR']

• Host name: $_SERVER['SERVER_NAME']

• Latest boot: shell_exec('uptime') or read the file /proc/uptime containing 2 values. 1st is Uptime in seconds

• Active and inactive processes: shellexec('ps -eF') process the output according to your needs.

• Temperature

  $temp    = exec('lm_sensors | grep \'°\'');
  $tempr   = explode('+', $temp);
  $tempval = preg_replace("/[^0-9,.]/", "", $tempr[1]);
  

• Memory being used: memory_get_usage(true) (for your PHP script)

• Total memory being used on the server: parse the output of the command free (contrib. @Guilhermenascimento)

• Total memory: read the file /proc/meminfo

Edited based on @Guilhermenascimento’s comment:

"for lm-Sensors to work, the server must have installed it and usually SHARED servers cannot install on their own (maybe the server has installed or not installed)."
