Or 3971k if kilo = 1024...

The Y-axis is still showing 1.1k/2.2k/3.3k/4.4k on the left, as the 
scale references. This target is a 95th percentile 30-day usage trend, 
so it's normally very slow to change, but has shifted up to 3981k by now 
(with the same axis).  I think one of this customer's servers has been 
rooted or otherwise hacked, as they're sending us (we're their ISP) 
about 7.2Mbps to give to the Internet on a Sunday afternoon.  I'm 
expecting (and hoping) the level to shoot up a lot in about 6-12 hours, 
so that'll help shift the numbers around a bit.

This is MRTG 2.9.17 on Red Hat 8.something, if that helps.

In addition, a similar target on this same port is showing a "proper" 
scale of 1.1M/2.2M/3.3M/4.4M:


Target[hstn-01.et.14.14.3]: `/usr/local/bin/burst 
MaxBytes[hstn-01.et.14.14.3]: 750000
AbsMax[hstn-01.et.14.14.3]: 12500000
Title[hstn-01.et.14.14.3]: Burst
PageTop[hstn-01.et.14.14.3]: <H1>Burst Level for XXX XXX</H1>

ThreshProgOKI[hstn-01.et.14.14.3]: /usr/local/bin/speedclearin
ThreshDesc[hstn-01.et.14.14.3]: XXX XXX


(FYI, I have two similar targets because i used to collect these targets 
manually, but now collect them automatically.  Because they're 30-day 
trends, I have to keep the old one in service for at least 45 days.)
