Max Schubert, Derrick Bennett, Jonathan Ginés, Andrew W. Hay, John A. Strand · 2008
Nagios is an Open Source network, hardware, and application monitoring program. It is designed to inform system administrators of problems on their networks before their clients, end-users or managers do. Nagios is a SysAdmin's best friend. Nagios is installed on over 300,000 machines worldwide, and truly is a global product: approximately 25.6% of users are in the U.S., and 30% in EMEA. Nagios can monitor everything from network bandwidth to the temperature and humidity in a server room. SysAdmins are able to use Nagios for such a variety of purposes through custom software "plug ins" and third party hardware. SysAdmins customize these plug ins instructing Nagios to monitor the servers, applications, or devices that are most critical to their network infrastructure. These plug ins also allow SysAdmins to integrate Nagios with other monitoring devices and applications like Snort and Wireshark.
