Hi all 
I'm trying to create a graph that would represent all the ICMP availability for all ICMP capable-devices and machines within an IP range.
The problem :
- I can only add items from hosts that are actually stored in the Zabbix's database
So, does it means I have to include all existing ICMP capable-devices and machine, before being able to graph their ICMP/Ping availabilty
(I think I must missing something, because the discovery rules references hosts with simple checks, even if they're not in the database, so it would be great to use those simple checks)
