Hello, I am using Nagios to monitor the bandwidth usage of a couple of switches/routers via the check_local_mrtgtraf command. The graphs I handle via pnp4nagios. The problem I encounter is the following: if the monitored bandwidth is at one point expressed in KB/s and then I bring a lot of traffic through the router the, unit is changed into MB/s. The graphed values seem not to take into consideration the change of the measurement unit meaning that the 50KB/s seems to be at the same height as the 50MB/s value in the graph. Can anyone please help? Thank you!
