I did so many (very interresting) upgrades last year, I can't remember since wich version I have the problem
I think since 0.8.7.0.I have a Cacti test plateform and a prod plateform (It means I don't test every plugins I see for fun on prod...)
Today, on 0.8.7.a, someone noticed that
- when I create a graph with 2 datas sources (number of sessions of 2 cluster Firewalls for instance)
- I graph the 2 "MAX" value (it's tactical
) in the Graph Item (CF Type)- the graph is 1 Area + 1 stack.
As a result:
- All-data-sources (ALL_DATA_SOURCES_NODUPS) is correct for MAX ( Max of (dataSource1 + dataSource2) ).
but
for AVG, MIN and LAST, the All-data-sources only consider 1 data source (the one defined in the line). In fact, I don't really understand what is calculated...
It's the same problem if I graph LAST or AVG (and MIN I imagine).
It works fine if I graph MAX, AVG (invisible) and LAST (invisible) but it's a hudge definition that I can't apply on all my existing aggregated graphs.
And however, I'm not so newbie, there's 2 years I use Cacti
Here is the graph debug:

And a graph result example.
Did i I miss something on a version ? Is it normal ?
As I had pb with Thold, perhaps I broke something...
Many thank's in advance.
