+Linfo – Shows Linux Server Health Status in Real-Time
+============================================================
+
+
+Linfo is a free and open source, cross-platform server statistics UI/library which displays a great deal of system information. It is extensible, easy-to-use (via composer) PHP5 library to get extensive system statistics programmatically from your PHP application. It’s a Ncurses CLI view of Web UI, which works in Linux, Windows, *BSD, Darwin/Mac OSX, Solaris, and Minix.
+
+It displays system info including [CPU type/speed][2]; architecture, mount point usage, hard/optical/flash drives, hardware devices, network devices and stats, uptime/date booted, hostname, memory usage (RAM and swap, if possible), temperatures/voltages/fan speeds and RAID arrays.
+
+#### Requirements:
+
+*   PHP 5.3
+
+*   pcre extension
+
+*   Linux – /proc and /sys mounted and readable by PHP and Tested with the 2.6.x/3.x kernels
+
+### How to Install Linfo Server Stats UI/library in Linux
+
+First, create a Linfo directory in your Apache or Nginx web root directory, then clone and move repository files into `/var/www/html/linfo` using the [rsync command][3] as shown below:
+
+```
+$ sudo mkdir -p /var/www/html/linfo 
+$ git clone git://github.com/jrgp/linfo.git 
+$ sudo rsync -av linfo/ /var/www/html/linfo/
+```
+
+Then rename sample.config.inc.php to config.inc.php. This is the Linfo config file, you can define your own values in it:
+
+```
+$ sudo mv sample.config.inc.php config.inc.php 
+```
+
+Now open the URL `http://SERVER_IP/linfo` in web browser to see the Web UI as shown in the screenshots below.
+
+This screenshot shows the Linfo Web UI displaying core system info, hardware components, RAM stats, network devices, drives and file system mount points.

+Linux Server Health Information
+
+You can add the line below in the config file `config.inc.php` to yield useful error messages for troubleshooting purposes:
+
+```
+$settings['show_errors'] = true;
+```
+
+### Running Linfo in Ncurses Mode
+
+Linfo has a simple ncurses-based interface, which rely on php’s ncurses extension.
+
+```
+# yum install php-pecl-ncurses                    [On CentOS/RHEL]
+# dnf install php-pecl-ncurses                    [On Fedora]
+$ sudo apt-get install php5-dev libncurses5-dev   [On Debian/Ubuntu] 
+```
+
+Now compile the php extension as follows
+
+```
+$ wget http://pecl.php.net/get/ncurses-1.0.2.tgz
+$ tar xzvf ncurses-1.0.2.tgz
+$ cd ncurses-1.0.2
+$ phpize # generate configure script
+$ ./configure
+$ make
+$ sudo make install
+```
+
+Next, if you successfully compiled and installed the php extension, run the commands below.
+
+```
+$ sudo echo extension=ncurses.so > /etc/php5/cli/conf.d/ncurses.ini
+```
+
+Verify the ncurses.
+
+```
+$ php -m | grep ncurses
+```
+
+Now run the Linfo.
+
+```
+$ cd /var/www/html/linfo/
+$ ./linfo-curses
+```

+
+Linux Server Information
+
+The following features yet to be added in Linfo:
+
+1.  Support for more Unix operating systems (such as Hurd, IRIX, AIX, HP UX, etc)
+
+2.  Support for less known operating systems: Haiku/BeOS
+
+3.  Extra superfluous features/extensions
+
+4.  Support for [htop-like][1] features in ncurses mode
+
+For more information, visit Linfo Github repository: [https://github.com/jrgp/linfo][6]
+
+That’s all! From now on, you can view a Linux system’s information from within a web browser using Linfo. Try it out and share with us your thoughts in the comments. Additionally, have you come across any similar useful tools/libraries? If yes, then give us some info about them as well.
