Internode Nodemap is a network visualization tool. Using SNMP, it gathers a periodic snapshot of the current state of the network. Then, under instructions from its config file, it plots a series of "maps" of the network over the top of GIF images in the Web server's document root, using color and HTML CSS to indicate potential performance or reliability problems. The maps are hierarchical "drill-down" views of the network. The top-level map is a summary which can be clicked on to reveal specific details; these more specific maps can also have additional maps nested within.
MCS MyRoute helps diagnose connectivity problems with detailed network routing discovery and analysis, providing visibility to poor-performing networks and devices. It includes a Java applet that enables remote users to easily test connections from the MyRoute server. Essential diagnostic tools including traceroute, ping, reverse DNS, and whois are combined into a single graphical interface that analyzes Internet connections, reporting quick and essential data points for finding connectivity problems. An IP location database identifies the geographical location of IP addresses and Web servers, showing the path of an Internet connection on a global map.
TNV (The Network Visualizer or Time-based Network Visualizer) depicts network traffic by visualizing packets and links between local and remote hosts. It is intended for network traffic analysis to facilitate learning what constitutes 'normal' activity on a network, investigating packet details and security events, or for network troubleshooting. It can open saved libpcap (from tcpdump, windump, ethereal, etc.) formatted files or capture live packets on the wire, and export data in libpcap format or save the data to a MySQL database to enable the examination of trends over time.
trend is a general-purpose, efficient trend graph for "live" data. Data is read in ASCII format from a file or continuously from a FIFO, and is played in real-time into a multi-pass trend (much like a CRT oscilloscope or a strip chart). trend can be used as a rapid analysis tool for progressive or time-based data series together with trivial scripting.
