munin graphs ftp bandwidth incorrectly ???

[boatdesign]

My munin bandwidth graph is set to graph bits per second. For httpd traffic, it graphs accurately (in sync with what my datacenter graphs on their rtg graphs at the router.) However I notice when I do an ftp transfer at 3 mbps the munin graph spikes and shows ~30 mbps. This seems repeatable and if I stop the ftp transfer the graph returns to normal httpd traffic level which is around 3 to 5 mbps. If I resume the 3 mbps ftp transfer the graph spikes up to around 27 to 30 mbps again. Everything is bits per second here; the ftp account is a cpanel account main ftp account.
Any ideas?

Munin Issues

Hello,


After looking at your problem, it most likely has to do with the way it is seeing the disconnections. However, we would need to take a closer look, and in order to do that efficiently you would need to submit a ticket. There is a link at the bottom of this post. That would help us get you all fixed up as quick as possible.

Thank you,
