Now that we have the Zabbix server and agent either compiled and installed or installed from the distribution packages, and both daemons are running, you probably have a feeling that something's missing. We have only configured some low-level behavior, so where's the meat?

That's what the frontend is for. While, in theory, Zabbix can have multiple frontends, the only one with full functionality so far is the Zabbix web frontend, which is written in PHP. We have to set it up to configure Zabbix and get to those nice graphs everybody likes.
