Add two items in one trigger

[diegocito]

Hi all,

I would like to have a trigger with the % of free disk (monitored by snmp).
I have the items : disk_capacity & disk_used.
That's why I would like to add a trigger with the following expression :
{DNS_server:disk_used.max(60)}*100/{DNS_server:disk_capacity.max(60)}>0.9
But this don't work, It threats the first, and then the second expression, but not all in one (I have two graphs, not one for example)...
Is it possible to do this???

Thanks
Diegocito

Up please, I really need this.

Or doesn't exists a snmp oid which gives directly the free capacity of the hd??? (but I don't find it)

Thanks

What is your problem? Use this expression if unsure about operator precedence:

({DNS_server:disk_used.max(60)}*100)/({DNS_server:disk_capacity.max(60)}>0.9)
