Good day!

I found a problem and need your help to solve it.

I work with Zabbix 6.4.17., made changes to the VMware Hypervisor template.

To track changes in the pool size, I added a calculated item to this template:

Key:  vmware.hv.datastore.multipathSum[\{$VMWARE.URL},\{$VMWARE.HV.UUID}]

Aggregation: sum(min_foreach(//vmware.hv.datastore.multipath[\{$VMWARE.URL},\{$VMWARE.HV.UUID},*],1m))

During preparation, I was guided by the documentation https://www.zabbix.com/documentation/current/en/manual/vm_monitoring/vmware_keys#vmware.hv.datastore.multipath

and the Behavior depending on availability table at https://www.zabbix.com/documentation/current/en/manual/appendix/functions/aggregate/foreach

Conclusion: I discovered that the formulas do not work as expected in the Behavior table depending on availability.

Problems:

With Aggregarion sum(min_foreach(//vmware.hv.datastore.multipath[\{$VMWARE.URL},\{$VMWARE.HV.UUID},*],1m))

we get floating values ​​although the item metric values ​​are constant.  

With Aggregation sum(last_foreach(//vmware.hv.datastore.multipath[\{$VMWARE.URL},\{$VMWARE.HV.UUID},*]))

there are unsupported metrics, but suddenly they are used by sum too as opposed to documentation  https://www.zabbix.com/documentation/current/en/manual/appendix/functions/aggregate/foreach

Attach screenshots below.
