Nagios: System & Network Monitoring
Nagios: System and Network Monitoring shows how to configure
and use Nagios, an open source system and network monitoring
tool. Nagios makes it possible to continuously monitor
network services (SMTP, POP3, HTTP, NNTP, PING, etc.), host
resources (processor load, disk and memory usage, running
processes, log files, etc.), and
environmental factors (such
as temperature). When Nagios detects a problem, it
communicates the information to the sys admin via email,
pager, SMS, or other user-defined method; current status
information, historical logs, and reports can also be
accessed via a web browser. Nagios System and Network
Monitoring covers the Nagios core, all standard Nagios
plug-ins and selected third-party plug-ins, and shows
readers how to write their own plug-ins. The book covers
Nagios 2.0 and is backwards compatible with earlier
versions.
