[rrd-users] gigabit interfaces

[Michael Smith]

We are relatively new to using rrd and I wanted to get an
opinion/clarification on a configuration.  We have a generic interface 
configuration that consists of

<filename>,
"-b$boot_time",
"-s300",
'DS:InOctets:COUNTER:600:U:U',
'DS:OutOctets:COUNTER:600:U:U',
'RRA:AVERAGE:0.5:1:105408',
'RRA:AVERAGE:0.5:6:700',
'RRA:AVERAGE:0.5:24:775',
'RRA:AVERAGE:0.5:288:797',
'RRA:MAX:0.5:6:700',
'RRA:MAX:0.5:24:775',
'RRA:MAX:0.5:288:797'

Here is the delimma.  Some of the interfaces are Gigabit links.  With the
default step of 300 seconds, these interfaces can wrap more than once.
Mathmatically speaking, they can wrap once every 34 seconds if fully 
loaded.

So, if we reduced the step to 30 seconds, im guessing we have to 
increase the number of samples kept by a factor of 10 as well.
Is that correct?  Has anyone else dealt with this before (high volume
counters constantly wrapping) and what was your solution?
