caclulated item of two hosts

[zabbixx]

Hello is tehere a posibility to create one item and calculate there items from other hosts?

last("connUnitPortStatCountTxElements.1") + last("connUnitPortStatCountRxElements.1") + last("connUnitPortStatCountTxElements.2") + last("connUnitPortStatCountRxElements.2") +
last("connUnitPortStatCountTxElements.15") + last("connUnitPortStatCountRxElements.15") + last("connUnitPortStatCountTxElements.16") + last("connUnitPortStatCountRxElements.16") +

this will not works in HOST1

last("HOSTS2:connUnitPortStatCountTxElements.1") + last("HOSTS2:connUnitPortStatCountRxElements.1")

I think you created the Formula correctly.
Just wait for a little bit longer time.
It's not calculating right after creating - but after some "Update intervals"

Also, be careful with correct host name - in your example I saw two different names: HOST1 and HOSTS2
