Chapter 19. Network Troubleshooting > Monitoring the Network

Monitoring the Network

Another aspect of keeping your network healthy is monitoring network traffic and looking at the various processes and events related to network protocols. This means you actually have to be able to view the communication processes that actually take place on your network as data moves from servers to clients (and vice versa). Network monitoring is the process of viewing and analyzing network traffic, and network monitoring software packages are used to capture network data frames and examine them. A software package that can analyze protocol information in a data frame is often referred to as a protocol sniffer.

Caution

Protocol sniffers and network monitoring software can be a big help in managing a large network. The problem with these types of software packages, however, is that they can also be used to actually steal and read information on a network, such as usernames and passwords. Protocol sniffers are often used by hackers to gain information about networks they wish to steal information from. We will talk more about hacking/cracking in Chapter 20, “A Network Security Primer.”
