smartmontools

Self-Monitoring, Analysis, and Reporting Technology
needs a MTA; if one isn't installed you'll get exim/sendmail? on debian and postfix on ubuntu as a dependency when installing smartmontools.
for health of your disk(s) you'd run sudo smartctl -H /dev/sda

zabbix

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';
flush privileges;
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.

login problem: admin/zabbix and not admin/<blank> as mentioned on the site!!
