The RRD index page lists all of the interfaces that are currently being monitored using RRDTool.

Clicking on any of the charts will show a detailed view of utilization over the last day, week, month and year. Clicking on a chart in this detail view will show all the charts relating to that interface and time interval (including, errors and packet types).

Note: Before you can view RRD charts, you must first enable RRD collection.
