Calculate duration based on item's value

[dougbee]

Hi all,

Running Zabbix 5.4.6. I'm working on something to calculate a device's consumption (a boiler, in this case) based on the duration of an item being within a certain value range. Given the sample data in the attached graph, I know some ranges:

State A is > 300 watts
State B is around 175 watts
State C is around 60 watts

So in this case, I know that in State A, my burner is running and consuming oil. I'd like to create a calculated item based on the total time that the item is > 300 watts - be it for a day, week, month, year, etc.

Any thoughts on how I can do that?

Thanks so much!

I guess you would also need to record the duration for a state. Together with the last(duration) you should be able to calculate the cost.

Tracking the duration of each operating state is a practical approach for estimating actual consumption. Combining runtime data with power thresholds can provide much more accurate calculations over daily or monthly periods. Similar monitoring methods are often used when evaluating equipment performance and maintenance needs for components such as a Suction Oil Filter Element.
