[rrd-users] help with update

[Ricardo Kleemann]

Hi Simon,

Actually I've been accumulating data for about 1 day now.

I must have not provided the correct create command then, as you
mentioned regarding step declaration.

Do I just need to add --step 300 there?

How long did you do updates for ? You won't see any values in the 
database until you've completed a consolidated period AND you have at

least (in this case) 50% of that period covered by data. If you are 
entering data every 5 minutes, it may take 2 or 3 updates before data

appears.

Also, is it a typo/copy&paste error, because I don't see a step 
declaration in that rrd tool create command ?
