How to limit max RRD Graph Size on Throughput to 100mbit?
I get these ridiculous spikes on my RRD graphs of 400mbit or more, but the physical layer is only 100mbit. I've tried the removespikes.pl script but to no success.
Is there a way to cap one of the graphs at 100mbit?
So I found a ticket where they increase the max for 10GBE: https://redmine.pfsense.org/issues/2979
The magic file appears to be https://redmine.pfsense.org/projects/pfsense/repository/entry/etc/inc/rrd.inc#L270, though the value 2500000000 doesn't make much sense (it's not a power of two).
My best guess is that 210GBE is three orders of magnitude more than 2100Base-T, so I should maybe try reducing 2500000000 to 2500000 and see what happens.
That didn't work… sigh. damn. Argh.
