Maximum value incorrect on additive graphs

[ashke]

Re bump.

[bleearg]

I found this post while investigating a similar issue with graphs that have multiple sources, all totaled up. Looking at my graph debug output, I see that some cdefs are referencing the MIN function, but I don't have MIN defined in any of the graphs:

Code: Select all

DEF:c="/opt/web/virtual/cacti/rra/edge01_traffic_in_2204.rrd":traffic_in:AVERAGE \
DEF:d="/opt/web/virtual/cacti/rra/edge01_traffic_in_2204.rrd":traffic_in:LAST \
DEF:e="/opt/web/virtual/cacti/rra/edge01_traffic_in_2204.rrd":traffic_in:MIN \
DEF:f="/opt/web/virtual/cacti/rra/edge01_traffic_in_2204.rrd":traffic_in:MAX \

I've got AVERAGE for my first AREA and subsequent STACKS, then CURRENT, AVERAGE, and MAX defined for my GPRINTs. Is it possible that these two problems are related?

Still looking for help on this.

I am also seeing this issue on graph's that have Data Sources from multiple devices.

As you can see in the image the 'current' and 'average' totals are correct but the 'Maximum' totals are not

As a poster mentioned above I also get the MIN Def's in there but these are not being used anywhere.

Code: Select all

RRDTool Says:

OK

[gandalf]

Unfortunalety, this is a known bug, assigned to me. To avoid breaking existing graphs, the workaround is quite tricky and may still require some thinking
Reinhard

[manaf]

has anybody solve this bug!

[gandalf]

Yes, me. Will be part of 087c.
Reinhard

[manaf]

Yes, me. Will be part of 087c.
Reinhard

gandalf,, when the 087c will be released??

[gandalf]

There's a BETA1 out there. But the bug fix was posted afterwards. To verify, please check out latest SVN; for testing purpose only
