10G interface graph problem over 800Mbps

[Lutz]

Hello,

I looked at the discussion about wrong graphs because data above 800Mbps.
Now I have the following strange phenomenon at my cacti.

On one server we have installed 2 versions off consolidation.
1. normal consolidation
2. no consolidation (5min graph for the whole year)

The two graphs from the same interface show me different output over 800Mbps border.

1. normal consolidation: graph is not interrupted over 800M
2. no consolidation: graph is interrupted over 800M

Normaly there should be both graphs interrupted, because both have the max value of 100000000 ?!

Regards
Lutz

pictures ? debug messages ? rrdtools command with parameters ?

Attached are 2 graphs of the same interface.
What debug/rrdtools commands are related to this? I'm not the cacti expert...


Thanks

If rrd MAX is the issue, the data is lost.
Try setting MAX value for all data sources of those rrd files to "U" using "rrdtool tune". New values should be fine, then
R.

Thanks Gandalf,
it works now fine.

There is one question open:
We have 2 cacti-server, 1x Ver 0.8.7b and 1x Ver 0.8.7e
I checked all rrd's of 10G interfaces for max value.

Ver 0.8.7b
max = 1.0000000000e+10

Ver 0.8.7e
max = 4.2949672950e+09

Why are they different?

Note: my solved problem was unique to interfaces with no consolidation

On rrd file creation, Cacti (by default, unless someone/some template changed it) will take the ifSpeed and use that for the rrdfile MAX. The fact they're different over time, suggests your defaults have been altered.
