=== Configuration details ===
You can mostly follow the guide at:
http://observium.org/wiki/Installation

with the following notes:
- Installation directory is %%WWWDIR%%
- The following lines should be added to /etc/crontab:

33	*/6	*	*	*	www	cd %%WWWDIR%% && %%PHP%% discovery.php -h all
*/5	*	*	*	*	www	cd %%WWWDIR%% && %%PHP%% discovery.php -h new
*/5	*	*	*	*	www	cd %%WWWDIR%% && %%PHP%% poller.php -h all
*/5	*	*	*	*	www	cd %%WWWDIR%% && %%PYTHON%% poller-wrapper.py 2

Notes:

- With newer MySQL databases you may need to disable strict mode for
  Observium to function:

	SET GLOBAL sql_mode = '';

- Apache needs mod_rewrite enabled; uncomment the line below in httpd.conf as needed.

    LoadModule rewrite_module libexec/apache24/mod_rewrite.so

- A minimal install can be created with the following steps and configuration file:

0: make sure apache and mysql are up and running.

1: create the database and a dbaccount with the following (my)SQL commands:

    CREATE DATABASE observium DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;
    GRANT ALL PRIVILEGES ON observium.* TO 'observium'@'localhost' IDENTIFIED BY 'notSecure';
    SET GLOBAL sql_mode = '';

2: create a minimal config file at:

	 %%WWWDIR%%/config.php

    containing:

<?php
$config['db_host'] = 'localhost';
$config['db_user'] = 'observium';
$config['db_pass'] = 'notSecure';
$config['db_name'] = 'observium';

3:  populate the admin user and initialize the database (as 'www' user):

sudo -u www %%WWWDIR%%/discovery.php -u
sudo -u www %%WWWDIR%%/adduser.php admin SomeInsecureAdminPassword 10

4:   and verify that collection is working:

sudo -u www %%WWWDIR%%/discovery.php -h all -d
sudo -u www %%WWWDIR%%/poller.php -h all -d

5: Install the above crontabs.

6: log in with a web browser; using the username 'admin' and the 
   password 'SomeInsecureAdminPassword'.

   Hosts can be added from the webinterface or from the commandline.
