Compare Traffic with 24h before traffic

[viniciusmbo]

Hello,

I´m using Zabbix 3.0.

I´m trying to create a graph that compares current traffic with 24h before traffic using time_shift parameter but it is not working.

I created a calculated item:

last("ifHCInOctets[Eth-Trunk0.1753]",86400)/last("ifHCInOctets[Eth-Trunk0.1753]")

But this formula only returns 1.

Thank you in advance.

When you created the Caclulated item, what "Type of information" did you select? Did you switch it from "Numeric (unsigned)" to "Numeric (float)"? When doing division, that might make a difference.

I tried both options, but with the same results, Always 1.

If I create a calculated item with two diferent items it Works and the results are not Always 1.

this code, for example works.

last("ifHCInOctets[Eth-Trunk0.1753]")/last("ifHCOutOctets[Eth-Trunk0.1753]")
