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.
