[rrd-users] Questions of new user

[Pavel Rubtsov]

Hi All!

Im new user of rrdtool, i have many questions (and i search for web, but some thin questions is still no ansver...; and sorry for my english... :)

1. How rrdtool does updating in time interval?

After creating of database and strict by step?
Or it countdown timer after last adding data?

Example:

i have --step 300
i update *.rrd base at 16:00:00 (h:m:s)
i update *.rrd base at 16:02:00
NOW next step begin in 16:00 or in 16:07?


2. Example:

i have --step 300
If i will update often, then 300 sec (for example every 10 seconds) what will be? Which data is stored?

3. I create rrd with:
--step 60

DS:test:GAUGE:120:0:100
RRA:MIN:0.5:1:30

i update every 60 sec with values:
10, then 20, then 30, etc.
But when i create graph i see NOT Minimum value, its looks like averaged... why?

i have rrdtool-1.2.15-cygwin-1.5.20.zip
