What Is Nagios Core? 什麼是Nagios Core?

Nagios Core is an Open Source system and network monitoring application.  It watches hosts and services that you specify, alerting you when things go bad and when they get better.

Nagios Core was originally designed to run under Linux, although it should work under most other unices as well.

Nagios Core 是一個開源的系統和網絡監控應用。它監控你指定的主機和服務，當有事情變壞或變好的時候給你發出通知。Nagios被設計運行在Linux系統下面，通常它在多數類UNIX操作系統下也能工作得很好。
