Please help on creating calculated prototype Item

[danielc]

Hello,

I am trying to create a calculated "Used space on datastore {#DATASTORE} (%)" of esxi nodes for graphs on multi nodes in zabbix.

I created the calculated prototype Item like this:

Name: Used space on datastore {#DATASTORE} (%)

Type calculated

Key: vmware.datastore.size[{$VMWARE.URL},{#DATASTORE},pfree]

Formula : ((("vmware.datastore.size[{$VMWARE.URL},{#DATASTORE},total]")-("vmware.datastore.size[{$VMWARE.URL},{#DATASTORE},free]"))/("vmware.datastore.size[{$VMWARE.URL},{#DATASTORE},total]"))*100

Then I saved this item and press "Create Enabled", but it is not creating the items.

I am not sure if there is anything wrong of the formula,

Would you please help me ? Thanks

Daniel
