Hello,
I've build an application to monitor my heating system.
I keep in a log file the values I give to rrdtool by the update function.
When I proceed a fectch on a certain amount of time, the values doesn't
match the values I've stored in the log file.
Here is an extract:

I hope it will be readable, of course I can deliver a pdf if needed.
The values given to update is "d conso Wh/min" in monitor.log
The values fetched from rrd file is also "d conso Wh/min"
When reading the first to line it seems like I have a 100 factor but later
it doesn't match.
The DEF is a COUNTER and I made an AVERAGE every minute.
I can also provide rrd file, and code extract from my python script.
An idea ?
Thanks
