Software Update: Nagios Core 4.0.7

Version 4.0.7 of Nagios Core has been released. The program allows you to monitor various parts of the network and services on servers. Nagios Core can monitor smtp, pop3, http, and nntp services, among others, and resources such as processor load and disk usage.
