Download Nagios Core 4.4.0

The Nagios Core program allows you to monitor different parts of the network and services on your servers. The program can monitor smtp, pop3, http, and nntp services, among others, and resources such as processor load and disk usage. If something happens that you want to be kept informed about, you can receive notifications by mail or on your pager.
