cacti graph problem

[hamoud5]

Dear,

i face problem in graph that plot a 50 GIG Ethernet in Cisco router which connected to 50 GIG Ethernet in Juniper router, the graph is plotting normally while the traffic is less than 30 GIG, but when the graph exceed 30 GIG the graph stop plotting, and i refer back to Cisco support and they inform me that there is no problem in the Router and the problem in Cacti, i try to investigate in the problem but i can't found any solution, the graph is attached below and i use polling interval every five minutes, so kindly if any one can help to find solution for this problem.

thanks,

Yes, this is the only graph, as this is the only 50 GIG Ethernet i have.

That looks like a limitation of 32-bit integer.
(2^32 * 8) / (1000^3) = 34.36

But somehow odd.
From what you mentioned in the below topic,
- http://forums.cacti.net/viewtopic.php?p=221934#p221934
normally these traffic values will be divided by 300(sec) because that is "rate" in 5 minutes.
So its limitation should be 114 megabits.

Did you select "GAUGE" incorrectly for 'Data Source Type' in your data template of traffic?

// Sorry my English

[hamoud5]

I already use SNMP v2c and 64-bit counters, and the data source type is counter not GAUGE

Hmm,
does your RRD file correspond with the data template?
% rrdtool info xxxx.rrd

[hamoud5]

yes, the RRD file correspond with the data template

What is "max" value in your RRD?
