Overview

• Monitoring of network services (SMTP, POP3, HTTP, ICMP (ping)^[4]
• Limited monitoring of host resources (processor load, disk usage) on a majority of network operating systems, including Microsoft Windows and Linux through agent-based testing
• Plugin design that allows users to easily develop their own service checks depending on needs, by using PHP (or other languages or scripts wrapped in PHP)
• Some ability to define network host hierarchy using "master" nodes allowing link failures to suspend monitoring^[5]
• Event-based system allowing failure notifications to be sent in customised email (suitable for email-to-SMS) or to utilise third-party notification scripts via a plug-in
• Ability to define event handlers to be run during service or host events for proactive problem resolution
• Automatic data retention cleanups
• Full web-interface for management and monitoring
• Ability to "publish" views and graphs within third-party web pages
