Network administrators want to know what happens on their network. This is both from a machine and software perspective as well as from a user perspective. This is monitoring the network. The idea is to watch what happens so that the network can keep functioning during business or critical times.
Intranet software sits on a server. It monitors all data traffic between the Internet and the intranet. Moreover, it can monitor all traffic on the intranet itself. It works by examining every Internet Protocol (IP) packet moving in and moving out of the intranet. It examines both the IP header and the data itself. The IP header keeps track of the address, source, and destination. The data can be documents, spreadsheets, e-mail, and so on.
What should monitoring software provide the network administrator? It should provide information about who is logged on, who is sending e-mail, and who is signing in late or signing out early. It should record key strokes if necessary.
In the next few sections we will look at some top intranet monitoring software tools. These tools help IT administrators monitor the computer operations within an intranet.
