AEleen Frisch, author of Essential System Administration wrote an 
excellent series of articles for the O'Reilly & Associates Web site 
last year describing a few of her favorite tools. She says, 
"In general, these tools can make your job easier no matter what 
Unix operating system your computers run." On the list are the Amanda 
backup utility, LDAP, GRUB, and the Nagios monitoring package.  
Frisch's article on Nagios (formerly known as Netsaint) takes an 
in-depth look at Nagios and provides screenshots and annotated 
configuration files detailing key points. You can find out more 
about this useful tool from Frisch's article or from the Nagios 
Web site.
