Device Main Window Each device on t he MegaVisi on map has a main window that di splays the front pa nel of that device. From thi s panel you can quickly monit or the device’s operat ions in real time. LEDs on the port image buttons indicate activity, collisions, and flow control for each port on the device.
Control Wi ndows The Device Ma in Window provides access to a set of C ontrol Windows, through which the Network Manager can perform remote control operat ions on the managed devices, change the device parameters.
Graphics Support You can graphi cally view counters data as s peedometer, li ne, or bar gra phs. These alt ernate views o f data make it easie r to an alyze and compare s tatistic s at a gl ance. A tilin g optio n allows you to neatly lin e up s everal graphi c windows on the screen.
Speedometers This type of display shows the insta ntaneous value of a selected counter in a speedometer- like window. The window contains a moving indicator, the counter category, and the current value.
Line Graphs The line gra ph feature provides a wide variet y of options for moni toring and compari ng data. In its sim ple st form , one graph for each counter is displayed in separate windows showing current act ivity.
in a new window. Figure 11b. M ultiple Line Graphs. For some s tatistic- to-grap h conve rsions, y ou will ne ed to use the mu ltiply coefficients to properly scal e graph lines , especiall y when you use two counter ca tegories, where values might have large differences.
