Calculating the maximum load of a processor core.

[Andrey.Gavenko]

Hello everyone!

I'm using zabbix 7.2.
The network device has several processors. My goal is to calculate the maximum and average load between the cores.
Using LLD, I form an array with the key cpmCPUTotal1minRev.[].
After that, in the template, an element cpmCPUmax1minRev of the "calculated" type is created with the formula:
max(last_foreach(/MyTemplate/cpmCPUTotal1minRev.[*])).

But as a result, I get an error:
Cannot evaluate expression: no input data for function at "max(last_foreach(/MyTemplate/cpmCPUTotal1minRev.[*]))"

What am I doing wrong? How can I solve this problem?

Thank you!

Hello everyone!

If anyone finds it interesting or useful, here is the right way:
formula: max(last_foreach(/{HOST.HOST}/cpmCPUTotal1minRev.[*]))

Thank you!
