Traffic Graph Incorrect?

[Crispy Beef]

Hi All,

I've recently setup Cacti on my Gentoo Linux box, previously I just used MRTG. I've got it running nicely but with one issue, the traffic graph seems to think that after transferring a large file at 1.1MB/s (8.8Mb/s) that the maximum is 438.66k. I know the file transferred correctly so this leads me to believe that either SNMP is reporting incorrect values - which I doubt - or my data source is incorrect in Cacti.

I've messed around with the SNMP - Interface Statistics data sources, used both 64bit and normal 32bit counters to no avail. I've deleted the .rrd file inbetween so it's had a fresh start and things don't get mixed up.

The max size setting is way above the maximum bandwidth possible fir the ethernet card and connection so I've ruled that out...

Any pointers would be most appreciated.

Cheers.

Please post a screenshot of that period in time from your graph. How big was your file? Transfer lasted longer than 5 minutes? And please visit ths graph at Graph Management, switch to DEBUG and post the rrdtool graph statement

Hi,

Thanks for the reply. I've now managed to sort the problem, it would seem that to data was incorrect due to messing around just after installation, I had changed some templates and data sources without deleting the RRA files holding the data.

I've now deleted the files and started fresh and all seems to be working well.
