calculated items

[mma]

Hello,

First, I'm a French student so... sorry for my (bad) English...

I want to calculate a very easy think : the used space in memory in a Windows.
I tried vm.memory.size[total]-vm.memory.size[free] and many others syntaxes but it doesn't work... With last() too...

If some can help me, I didn't find documentation on the syntax, just this page :
http://www.zabbix.com/documentation/...l/config/items

I always have :
20486:20100406:120013.652 Format error or unsupported operator. Exp: [vm.memory.size[total]]
20486:20100406:120013.652 Format error or unsupported operator. Exp: [vm.memory.size[total]]
20486:20100406:120013.652 Item [CYRES037:vm.memoryUsed] error: Format error or unsupported operator. Exp: [vm.memory.size[total]]

bye !

Hi,


You wil find the documentation for calculated items here:
http://www.zabbix.com/documentation/...lculated_items

In your case, I think proper syntax would be:

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