[rrd-users] MRTG to RRDtool Migration

[jon.hartman at verizon.com]

I'd like to migrate from MRTG to RRDtool, in particular to take advantage
of the 1 minute polling cycles. I have a couple of questions though:
 
1) Why does MRTG use PNG's and it's successor GIF's? I thought the open
source movement was trying to steer clear of any patented formats.
2) If I use RRDtool as the back-end and MRTG as the front-end, can I still
set the polling interval as low as every minute? If not, why not?
3) Why is MRTG limited to once per 5 minutes? Is it due to the logfile
storage math?
 
Thanks in advance for any assistance provided. I'm currently reading over
the docs available and trying my best to soak it all in. ;)

Thanks in advance,

-Jon Hartman
