For many years now, I have been using Cacti as the old school network monitoring system. This is a classical network monitoring system which you install, configure and forget as I runs without much maintenance.
Then someone asked me the network utilization graph for one of the MPLS links (20Mbps) which is currently peaking at 10Mb. In this graph, we have the Y-axis (left side) set at 10M max at this moment. I was asked if I can fixed the axis at 20Mb to give indication to the viewer that we still have enough traffic capacity for this MPLS link
