+Zabbix is a network management system created by Alexei Vladishev. It is designed to monitor and track the status of various network services, servers, and other network hardware.  Zabbix uses a client/server model, where one central server collects or receives information about several clients ("clients" being servers or devices you want to monitor).

-Use the virtual machine appliance rather than setting up a physical machine.  Yuck!
+The Zabbix "server" is the central server which collects information about all the other servers (the "clients").  This is usually the ''zabbix'' package in most Linux repositories.  The Zabbix server package installs a web interface, database schema, etc.

-===== Install zabbix-agent =====
+<note>The zabbix-agent for CentOS from andrew farley's repo has some problems I think, take care when upgrading.  You might need to manually remove zabbix stuff from ///var/log/zabbix//, ///usr/share/zabbix// and ///var/spool/mailbox/zabbix//.</note>

+==== Active vs Passive ====
+A Zabbix client can be "passive" or "active."  If you don't know the difference, you want passive.  A passive Zabbix client merely sits and listens, waiting to be periodically queried by the central Zabbix server.  An active client, on the other hand, actively sends status information to the central Zabbix server.
+==== Install zabbix-agent ====
+Installing the agent from apt:
 <code>$ sudo apt-get install zabbix-agent</code>
-===== Configure zabbix-agent =====
+==== Configure zabbix-agent ====
 Edit the agent's config file, paying specific attention to the "Server" line:
-<code>$ sudo vim /etc/zabbix/zabbix_agentd.conf
+<code>$ sudo vim /etc/zabbix/zabbix_agentd.conf</code>
-===== Start zabbix-agent =====
+Set at least these options in the config file:
+<code>Server=172.26.16.249
+DisableActive=1</code>
+==== Start zabbix-agent ====
 <code>$ sudo /etc/init.d/zabbix-agent start</code>
