-		+	* monit for monitoring and triggering; munin for the graphs
-	* ~~on debian/ubuntu use aptitude to install zabbix (zabbix-server-mysql, zabbix-agent, zabbix-frontend-php (~~for ~~the web gui))~~	+	*
-	* however this installed 1.6.4 and ~~not 1.8 which came out in dec 2009~~	+
-	* it needs apache and mysql	+
-	* the installation includes dependencies, creatings a user and group zabbix and a database plus populating it	+
-	* edit /etc/services and add: zabbix_agent 10050/tcp, (new line) zabbix_trap 10051/tcp	+
-	* timeserver can be handy	+
-	* edit /etc/php5/apache2/php.ini -> max_execution_time = 300 and date.timezone = Europe/Amsterdam	+
-	* the frontend is installed in /usr/share/zabbix	+
-	* you can make a /home/zabbix/public_html or /var/www/zabbix directory	+
-	* into this you cp everything from /usr/share/zabbix	+
-	* then you need to edit /etc/apache2/sites-available and /etc/apache2/sites-enabled sothat the webserver knows where to look for the ~~zabbix web interface~~	+
-	* ~~http://www.zabbix.com/wiki/howto/install/debian/zabbix18_on_debian_50~~	+
-		+
-	* create database zabbix character set utf8;	+
-	* grant all privileges on zabbix.* to 'zabbix'@'localhost' identified by 'zabbix';	+

-	* exit;	+

-	* cat mysql.sql \| mysql -u zabbix -p zabbix	+
-	* cat data.sql \| mysql -u<username> -p zabbix	+

-	* have gotten very fed-up with all the problems installing zabbix. if the documentation had been correct and up to date i may have been less feb up. but so many inconsistencies. it gets my thumbes down. back to nagios.	+
