I have MRTG running on 3 of our servers, each at a different site. They
are all running the same application which uses a sustained amount of
bandwidth over a few hours, usually around 5-10 Mb/s. The application
allows us to limit the bandwidth.
On 2 of the sites, the MRTG bandwidth graphs are very close to the
bandwidth limit we have set up. On the 3rd site however, it is showing
~1/3 more bandwidth than we have the limit set to (ie, if the limit is
5 Mb/s, we're seeing 7Mb/s.
Does anyone have any ideas about this? Are there any tools I can use to
test the bandwidth use? How about something that can reliably generate
traffic at a given limit?
