Analysis of the machine / server using php

Navigation
5

I am creating a system report, I honestly did not know that PHP did this, I searched and found it did, but I did not find a 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 ..

  • Address information - > Server IP, Hostname
  • System - > Last boot, active at what time, active and idle processes, CPU temperature and 'SYS'
  • Memory Usage - > How much of the total, how much is being used

    • If there is an article, or guidance to get it, thank you.

    There is an interesting project in 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 at 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:

  • Unpack the source code that can be downloaded here to the root of the server.

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

    cp phpsysinfo.ini.new phpsysinfo.ini

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

    • Verify that include_path entry contains .

    • Since phpSysInfo requires access to many files in /proc among others, it is important to have safe_mode disabled:

      To do this in the file php.ini , change the line from safe_mode to: 

      safe_mode = Off

    Finally, ensure that the PHP extension is installed with the name php-xml , being the same thing needed for a correct operation of phpSysInfo.

    • If changes have been made to the php.ini file, just reboot the server and you can start the fun.

    Note: To locate the php.ini file 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 innumerable potentialities of this project:

    And much much more ...

    Data format

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

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

    • IP: $_SERVER['SERVER_ADDR']

    • Host Name: $_SERVER['SERVER_NAME']

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

    • Active and inactive processes: shellexec('ps -eF') process 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

    Editing based on @GuilhermeNascimento's comment:

    "For lm-sensors to work, the server must have it installed and usually SHARED servers can not be installed on their own (perhaps the server may or may not have been installed)."
