InterMapper provides a graphical view of a network and tests the routers, servers, workstations, and other equipment attached to that network using pings, SNMP, and various server probes. Its on-screen maps can be printed to document the network configuration. InterMapper also monitors the utilization and traffic and error rates on WAN and LAN links within the network. When InterMapper detects a problem, it sends notifications to one or more responsible individuals. Finally, InterMapper has a built-in web server that allows the network manager to view the network health from a standard web browser. What's new in this version: InterMapper can now use an LDAP, Active Directory, Open Directory, or Radius server to authenticate users. Updated probes (Xserve RAID; Cisco IP SLA); VLAN information in Interfaces window; shared polling feature; autolayout of devices
