Benefits¶

• Monitoring of network services (SMTP, POP3, HTTP, NNTP, ICMP, SNMP, FTP, SSH)
• Monitoring of host resources (processor load, disk usage, system logs) on a majority of network operating systems, including Microsoft Windows with the NSClient++ plugin or Check MK.
• Monitoring of anything else like probes (temperature, alarms,etc.) which have the ability to send collected data via a network to specifically written plugins
• Monitoring via remotely run scripts via Nagios Remote Plugin Executor
• Remote monitoring supported through SSH or SSL encrypted tunnels.
• A simple plugin design that allows users to easily develop their own service checks depending on needs, by using their tools of choice (shell scripts, C++, Perl, Ruby, Python, PHP, C#, etc.)
• Available data graphing plugins
• Parallelized service checks
• The ability to define network host hierarchies using ‘parent’ hosts, allowing the detection of and distinction between hosts that are down or unreachable
• Contact notifications when service or host problems occur and get resolved (via e-mail, pager, SMS, or any user-defined method through plugin system)
• The ability to define event handlers to be run during service or host events for proactive problem resolution
• Automatic log file rotation
• Support for implementing redundant monitoring hosts
• An optional web-interface for viewing current network status, notifications, problem history, log files, etc.
• Data storage via text files rather than database
