Calculated Item is Unsupported until values are received

[bturnbough]

I have two items:

ifspeed-[{#SNMPINDEX}]
.1.3.6.1.2.1.2.2.1.5.{#SNMPINDEX}

ifinoctets-[{#SNMPINDEX}]
.1.3.6.1.2.1.2.2.1.10.{#SNMPINDEX}

These are located in a discovery template.

Also located in that same discovery template is a calculated item:

100*(last("ifinoctets-[{#SNMPINDEX}]")/last("ifspeed-[{#SNMPINDEX}]"))

When a template is initially applied to a host, the calculated item immediately goes unsupported because it has no data to work with. How do I keep this from happening?

You can't. It happens to me so many times. But once the item gets the data it will automatically change to 'enabled'. Try to tail your zabbix log file to see if something is happening.
