Misleading graph

[artumirichard]

Hi all

Newbie cacti user here confused about this graph



It makes no sense to me that a 1 minute average and a 5 minute average and a 15 minute average should ever look like this. Because they are supposed to be averages.

Can anyone shed light on what is going on here?

[artumirichard]

Perhaps I ought to be more specific.

My reading of this graph shows that the 15 minute average is always nearly higher than the five minute average which in turn is almost always higher than the one minute average.

That implies that my system is almost always experiencing a reducing load, even when the graph is showing the load increasing.

That bit around 15:00 is just bizarre.

This is a default cacti install on my local desktop for testing purposes. If I can't rely on this graph being correct it throws the whole thing into doubt.

[artumirichard]

OK. It's because it's a stacked graph which is inappropriate for this kind of data.

Correct. We will change this with next version.
