Nagios, open source host/server/network monitoring software

在多伺服器部署的網路環境,MIS想要一手掌控全局,需要使用網路及伺服器監控的套裝軟體,雖然有不少商業軟體提供整合良好的功能,但考慮價格及客製化擴充需求,Open Source solutions是許多企業最終的選擇,在提供整合監控功能的開源軟體中,Nagios算是頗受好評的一套軟體。

Nagios® is an Open Source host, service and network monitoring program. Where can you get it? Right here. Can you get support for it? Yes! Get more answers to some of your basic
questions about Nagios here.

Overview

Nagios is a host and service monitor designed to inform you of network problems before your clients, end-users or managers do. It has been designed to run under the Linux operating system, but works fine under most *NIX variants as well. The monitoring daemon runs intermittent checks on hosts and services you specify using external "plugins" which return status information to Nagios. When problems are encountered, the daemon can send notifications out to administrative contacts in a variety of different ways (email, instant message, SMS, etc.). Current status information, historical logs, and reports can all be accessed via a web browser.

Features

Nagios has a lot of features, making it a very powerful monitoring tool. Some of the major features are listed below:

  • Monitoring of network services (SMTP, POP3, HTTP, NNTP, PING, etc.)
  • Monitoring of host resources (processor load, disk and memory usage, running processes, log files, etc.)
  • Monitoring of environmental factors such as temperature
  • Simple plugin design that allows users to easily develop their own host and service checks
  • Ability to define network host hierarchy, allowing detection of and distinction between hosts that are down and those that are unreachable
  • Contact notifications when service or host problems occur and get resolved (via email, pager, or other user-defined method)
  • Optional escalation of host and service notifications to different contact groups
  • Ability to define event handlers to be run during service or host events for proactive problem resolution
  • Support for implementing redundant and distributed monitoring servers
  • External command interface that allows on-the-fly modifications to be made to the monitoring and notification behavior through the use of event handlers, the web interface, and third-party applications
  • Retention of host and service status across program restarts
  • Scheduled downtime for suppressing host and service notifications during periods of planned outages
  • Ability to acknowledge problems via the web interface
  • Web interface for viewing current network status, notification and problem history, log file, etc.
  • Simple authorization scheme that allows you restrict what users can see and do from the web interface
