We have ADSL connection shared by 20 computers. I want to monitor bandwitdh usage of each computer or IP. Brand of the ADSL modem is AirTies but I do not know the model (if necessary I can learn). Modem supports SNMP and I know the password of the modem.
I can not install any software to each computer since they are not mine but I can install any software to my computer which can be open 24 hours/day.
I tried MRTG and PRTG but they showed total bandwidth usage. I suppose PRTG is able to do what I want but I do not know how to configure it (maybe OID is required but I did not see any OID in the control panel of the modem)
