When you display statistics from an Intel® hub or switch device viewer, cumulative figures (counters) since the last reset are arranged in a table. You can also display real-time statistics as a graph or bar chart. Each type has advantages and disadvantages.
Table display
- Tables are the only way to display status (non-statistical) information such as a list of MAC addresses.
- Tables aren't good for displaying what's going on right now with statistics. Most table numbers are totals since the last time the device or device counters were reset, whenever that was. If a table shows 800,000 collisions, you have no idea when they happened.
Graph display
- Graphs clearly display changes in statistics since the last poll interval what's happening now.
- Graphs also offer short-term perspective, because they display recent levels (up to 100 or more data points, depending on the width of the graph window) since you opened the graph.
- Graphs can be unwieldy. Because each graph can display only six variables, a single table could bring up three or more graphs.
Chart (bar chart) display
- Charts clearly display what's happening now, like graphs.
- Charts, unlike graphs, show only what's happening now. There's only one data point per variable, and no perspective on what statistics were like 10 or 20 seconds ago.
- Charts can display a large number of table variables in the same window.
