Download Nagios 3.0a4

With the program Nagios you can monitor different parts of your network and services on your servers. Among other things, it can check for smtp, pop3, http and nntp services, and host resources such as processor load and disk usage. When something happens that you want to be kept informed about, you can set different notifications that can then be delivered by mail or pager. The program can easily be expanded to your own liking by using the existing plugin structure. For more information, we refer you to this page and a bunch of screenshots are up this page to watch. The developers have released the fourth alpha version of Nagios 3.0 with the following changes:
