I have tried the SNMP plugin a few minutes ago and here is what I get when running it from the command line: ./check_snmp_int.pl -H 192.168.2.1 -C public -n GigabitEthernet0/24 -k -w 200,400 -c 0,600 GigabitEthernet0/24:UP No usable data on file (1 rows) :(1 UP): UNKNOWN The interface name I took it from listing all available interfaces on the switch. Any ideas, please? Thanks!

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!
