[rrd-users] setting up the steps and heartbeat for database

[Marc Tobien]

Hi

I have a understanding problem how to set up a database for best practice
with rrdtool create name.rrd -step ??? DS:ds-name:heartbeat???   :min:max

The specialty is that I get approximately every 10 to 15 minutes a set of
3-9 dates for the database.

Every set of dates is holding the exact timestamp of measurement.

I do not have the problem to write the dates with update  into the rdd
database , but the unknown entered automatically if dates are not coming in
time or with a bad interval are messing up the average. See my example.
There can be a time different between taking the measurement and getting the
data's of 35 minutes. That is normal. If there is a breakdown of the line,
time can rise up to 900 minutes, that is the buffer of the  Device.

Data's will then be deliver after a reconnect.

 

e.g. set of data's coming in 

at 23:44
