Hi to everybody,
I'm trying to use rrdtool (1.3) to graph some trends (mainly for disks,
but also cpu and ram).
I've followed what others have done (i.e. copied every example that I
found) with LSLSLOPE and LSINT, and I thought I got it right.
Graphs seemed to prove I got it right. Thanks to all the people who
Then this weird thing started happening: as I added more data sources,
some predicted dates (reaching 75% o full capacity) looked very odd
(meanining: the date -when reaching the limit- would not correspond to
I started changing the end date of the graph and noticed that the base
parameter for the prediction (LSLSLOPE and LSLINT) changed too, which is
something I did not expect to happen. I thought that since those values
are based on real data (i.e. collected data), they would not change if I
extended the graph time in the future (since they are based on data in
the past, and they don't change).
What's wrong? What am I missing?
Thank you very much.
