I have just published my first book with Packt Publishing, the Nagios Core Administration Cookbook. It’s available as both an ebook and a paperback.
It’s in cookbook style, with some 360 pages of material in eleven chapters on making Nagios Core work as the centerpiece of network monitoring for busy systems administrators, including discussions on SNMP monitoring, passive checks, distributed and redundant monitoring, intelligent notification based on network structure and function, integrating with other tools like MRTG and RRDtool, and a few of the more essential extensions to the monitoring system.
The target audience is systems administrators who might know enough about
Nagios Core to set it up to send PING requests to a few hosts and to email
them, or perhaps check a few sites are working with
check_http, but that
haven’t really done much else with the system and are looking for some recipes
for expanding and refining its monitoring behavior to suit their network. For
those less familiar with Nagios Core the first couple of chapters recap the
very basics of hosts, services, and commands. The website includes
a pretty thorough overview of the contents, if this sounds like something in
which you might be interested.
