Chapter 4: Nagios Basics | Linux Journal |
 | | Nagios is in a position to reproduce such dependencies and to precisely inform the administrator of the failure of an important network component, instead of flooding the administrator with irrelevant error messages concerning services that cannot be reached. |
| | On the one hand Nagios allows a much finer distinction than just "ok" or "not ok"; on the other hand the distinction between (soft state) and (hard state) means that the administrator does not have to deal with short-term disruptions that have long since disappeared by the time the administrator has received the information. |
| | Nagios: System and Network Monitoring (No Starch Press, May 2006, http://www.nostarch.com/nagios.htm), written for Nagios 2.0 but backwards compatible with earlier versions of the software, will help sys admins maximize their use of the various Nagios features and take full advantage of its ability to keep systems running. |
