Hello Everyone, I came across one problem but so far i couldn't find good solution for my problem. Here is the problem..... I'm looking for a good open-source bandwidth measuring tool so that can measure throughput very well. I tried MRTG but it only measure bandwidth usage but it is difficult to see the allocated bandwidth unless you add in the configuration file. I really want to see if Service Provider truly allocated the agreed bandwidth for my site. We have VPN, so i want to know what bandwidth is allocated without asking the service provider. Thanks in advance. Regards
