I have looked on some specific interface and found out that it's all different, bellow is the comparison of the same traffic:

See? current Inbound traffic on Cacti is 5.91GB vs Observium 4.67GB (last)

Thanks

Dear Team,

I just install Observium and as I observed the graph traffic statistic seem not accurate compared to my Cacti graph monitoring system then I ask my Network Engineer to check which one is accurate traffic between Observium and Cacti, as the result after checking real traffic on my router device, Observium seems not accurate.

Note: Graph statistic value is different is around 1GB, this is a huge number.

Can anyone explain why or anyone experiences like me?

My real Out traffic should be around 5.78GB instead

Thanks so much.

Here is the two of it:

See it clear? and believe me it's the same interface on cisco router, I also double check on other interfaces it's not accurate as well.

Thanks so much for help

Actually, given the steepness of that uptime graph, this is almost certainly what is taking place.

Add 'snmp ifindex persist' to your routers config, then rediscover. Your Cacti will most likely need to be manually corrected (well, it was all manual the last time I looked at Cacti anyway, which is why we're here!)

It's not the same interface. One is showing ~5Gbps of inbound traffic and the other is showing it as outbound traffic.

Is it possible that your cisco router was rebooted recently? Does your router config have 'snmp ifindex persist'? Without that, your interfaces will magically move around with every reboot and both your Observium AND Cacti graphs will be wrong...

Anyways is traffic still fine when it goes over 8GB, right? I mean no problem with graph 64bits for Observium?

Becuase it looks strange after traffic goes over 8GB per I noticed (like decrease ).

Thanks, let me keep monitor it more till tomorrow,.

Your Cacti graph is 24 hours, your Observium graph is 6 hours. Try using the same time period as a comparison :)

Protip: If you think you've discovered a showstopping bug in a decade-old piece of software in its primary reason for existence, you've probably made a user error somewhere. :D

32bit counters wrap at the ~100Mb mark, not 8Gb.

You can see if a specific interface is collecting 32bit or 64bit values from the device settings, port page. _______________________________________________ observium mailing list observium@observium.org http://postman.memetic.org/cgi-bin/mailman/listinfo/observium
