4 | 5 |

6 | 7 | Simple Nagios Dashboard is a simple php based Nagios Dashboard. It is intended for a wall mounted monitor. It displays all host and service warnings. 8 | 9 | It requires that the Nagios status.dat file is available as JSON, it includes a module for that. 10 | 11 | Setup is very simple, only PHP 5 is required. No database or whatsoever. 12 | 13 | ### Installation 14 | 15 | - Extract code on Nagios Server 16 | - Edit `$statusFile` in `json.php` to point to the location of your nagios status.dat file 17 | - Install cronjob to generate JSON file: 18 | 19 | 20 | # /etc/cron.d/nagios-json 21 | * * * * * root /usr/bin/php5 /var/www/json.php > /var/www/nagios.json.tmp; cp /var/www/nagios.json.tmp /var/www/nagios.json 22 | 23 | 24 | - Extract code on webserver 25 | - Edit `config.php` and fill in your specific names and locations 26 | - ??? 27 | - Visit page in web browser and PROFIT!!! 28 | 29 | 30 | ### Credits 31 | 32 | - [PHP Nagios JSON by Christian Lizell](https://github.com/lizell/php-nagios-json) - GPLv3 33 | - [Job van der Voort](https://github.com/JobV), Design 34 | - Twitter Bootstrap 3 35 | -------------------------------------------------------------------------------- /index.php: -------------------------------------------------------------------------------- 1 | . 14 | require_once("./functions.php"); 15 | ?> 16 | 17 | 18 | 19 | 20 | <?php print($title .
