Router traffic graph is not correct in grafana

1

Hi ,

i have been monitoring the router traffic in centreon monitoring system and grafana. I noticed that centreon graph is accurate but in grafana i dont see the exact graph which means “current and avg value is wrong” the correct value is 255.4M , but in grafana i see as 2.35gbps. How to show the accurate value in grafana?

Below is the centreon graph:-

I fixed the issues. Now the graph looks fine.

thank you

Was it the unit(bit/s) that was wrong?

Nope.

I just add math function math/10 -> . it gives me the correct result in megabit/Sec

Hi @daniellee,

I cros checked the traffic value again in router.

For example:-

In router - Value is 234.85M
But in grafana:- value is 244.75M

In grafana i do see the value is slightly increased. how can i fix it ?

Which bytes per second unit did you choose? There are two: Data(IEC) and Data(Metric). If you chose Data(IEC) then it is not megabit/s - it is mebibyte/s.

Hi Danielle,

Thanks for your time. i am using the unit -> . data rate -> bits/sec

Actually grafana is working fine. The reason why i see the different value in centreon and grafana is that. The script execution time is different. But i am using the same script in both sides to collect metrics. i compare the value in grafana against with script value, its same. Hence i assumed that value is correct in grafana.
