    zabbix calculated item

    Hi,

    I have recently set up an item for monitoring for memory.
    The formula is:

    last("vm.memory.size[total]")-last("vm.memory.size[available]")

    The problem is when the agent was stopped (host was shut down), this item is still calculating from the last value from the last check, while the other items (vm.memory.size[total] and vm.memory.size[available]) were halted.
    It seems that the calculated item used the last value for the calculation but not the latest value (which should be unavailable).

    Is there a workaround on this?

    Thanks.
