[rrd-users] Understanding Questions

[Markus.Forrer at coop.ch]

Morning :)

Only to be sure that I am right or totaly wrong with my understanding of
RRD:

The following example:

I want to monitor a 1 Gigabit Link. For this I set the intervall to 30s.

I create the following rrd on friday.

./rrdtool create ../test/bdfalk_8004.rrd --step 30
	DS:input:COUNTER:600:U:U 
	DS:output:COUNTER:600:U:U 
	RRA:AVERAGE:0.5:1:6000 
	RRA:AVERAGE:0.5:60:700 
	RRA:AVERAGE:0.5:240:775 
	RRA:AVERAGE:0.5:720:797 
	RRA:MAX:0.5:1:6000 
	RRA:MAX:0.5:60:700 
	RRA:MAX:0.5:240:775 
	RRA:MAX:0.5:720:797

I think thats wrong!!

I wanna make the following graphs linke MRTG:

last day with AVERAGE and MAX of 30s Interval
last week with AVERAGE and MAX of 30min Interval
last month with AVERAGE and MAX of 2h Interval
last year with AVERAGE and MAX of 1d Interval

I suggest that I have to correct the rrd to the following for example for
AVERAGE

./rrdtool create ../test/bdfalk_8004.rrd --step 30
	DS:input:COUNTER:600:U:U 
	DS:output:COUNTER:600:U:U 
	RRA:AVERAGE:0.5:1:6000        #1 Sample every 30 sek for 2d and 2h
	RRA:AVERAGE:0.5:60:700        #60 Samples for the 30min Interval for
12,5d
	RRA:AVERAGE:0.5:240:775      #240 Samples for the 2h Interval for
50d
	RRA:AVERAGE:0.5:2880:797    #2880 Samples for the 1d Interval for
732days

Am I right??

How can I correct the last rra?? RTFM??

I wish all of you a good week.
