Naemon

Naemon is an open source system and network monitoring application. It monitors the hosts and services you specify, alerts you when problems occur and notifies you when they are resolved.

Naemon is based on Nagios 4.0.2 and aims to be a drop-in replacement for Nagios.

Features

• Monitoring of network services (SMTP, POP3, HTTP, NNTP, PING, etc.)
• Monitoring of host resources (processor load, disk usage, etc.)
• Simple plugin design that allows users to easily develop their own service checks
• Parallelized service checks
• Thruk monitoring web interface to edit settings and view current network status, problem history, log files, SLA reports, dashboards, business processes, etc.
• Ability to define a network host hierarchy using “parent” hosts, allowing detection of and distinction between hosts that are down and those that are unreachable
• Contact notifications when service or host problems occur and are resolved (via email, pager, or a user-defined method)
• Ability to define event handlers to be run during service or host events for proactive problem resolution
• Automatic log file rotation
