Network Management with Nagios

摘要

When I started with the John Deere Agricultural Marketing Center, we had 12 sites around the US and Canada. These locations had a mixture of equipment, older servers and desktops providing all functions from domain services to printing. That presented a problem to us functioning as a centralized IT organization. How could we manage and monitor the servers and WAN lines in these diverse sites? About two years ago, we decided to move the user data from the center of our network out to the edges. But how could we monitor all the equipment from multiple manufacturers across all the sites? To give you an idea of the equipment we were monitoring, each of our main sites had a Maxtor 4100 network-attached storage (NAS) server along with a Compaq 1600 serving as a print server and domain controller. Some of the small sites had Dell GX1 desktops serving as local print servers. At our main site, a Compaq TaskSmart N2400 was our main file server.
