NAME

nagios − host/service/network monitoring program

SYNOPSIS

nagios [-h | -v] <main config file>

DESCRIPTION

This manual page documents briefly the nagios, command. This manual page was written for the Debian GNU/Linux distribution because the original program does not have a manual page.

nagios Nagios is a host/service/network monitoring program. It has the following features:

Monitoring of network services (via TCP port, SMTP, POP3, HTTP, NNTP, PING, etc.)

Plugin interface to allow for user-developed service checks

Contact notifications when problems occur and get resolved (via email, pager, or user-defined method)

Ability to define event handlers to be run during service or host events (for proactive problem resolution)

Web output (current status, notifications, problem history, log file, etc.)

Nagios was written in C and is designed to be easy to understand and modify to fit your own needs.

On Debian systems it should be automatically started at boot time, and can be controlled manually by the /etc/init.d/nagios script.

OPTIONS

−d

−s

Starts Nagios, prints out service check scheduling information and immediately shuts down before starting to monitor anything. Note: Do NOT use this option while Nagios is running!

−v

Verify information in the configuration files. Nagios will *not* start monitoring any hosts when this option is supplied.

Note:

In order to start monitoring, you must supply the main configuration file as the only command line option.

FILES

/etc/nagios/nagios.cfg − main configuration file
/etc/nagios/hosts.cfg − monitoring configuration file
