Monitoring on the Mac
Apple has created many system monitors for the Macintosh. Some, as with Windows system monitors, analyze on the computer; but many system monitors manage the network as well as the computer. Most of the network monitors you find are for the Mac OS X, although you can search the Internet and find monitors for earlier Mac operating systems. Many Mac monitors employ PGP.
- InterMapper is one of the most common and popular shareware programs. Made by Dartware, LLC, InterMapper shows you a graphical view of your computer network, including routers, servers, workstations, and so on. InterMapper includes an autodiscovery feature that locates your resources and creates the network map for you. It also uses various built-in network probes, such as ping and SNMP, to help you locate connection problems, track e-mails, and find failed network components (www.intermapper.com).
- AysMon (Are You Serving Monitor) is one system monitor that also analyzes the network.
