Strip Charts InterMapper will display strip charts of MIB variables (% utilization, error counts, packet and byte counts, etc.) for different devices. These charts show the history of the device or link. In addition, the chart information may be saved to a log file, for later analysis. This stripchart shows the traffic for two links on our routers. It's easy to create a strip chart. Simply tear off a status window, and click an underlined variable. You can also drag other underlined variables to a strip chart window. The chart data can be saved as a tab-delimited file.
