"If you don't feel like going through this kind of config (and the typical maintenance) that surrounds these kind of (great) OpenSource products, try out a service from TruePath Technologies (http://truepathtechnologies.com/)! They use opensource software like Zabbix. Nice part is that they setup, maintain it and you get to use it (the fun part!)"

What are you talking about? - The fun part IS the configuration!
