Calculated values across an entire group

[xarous]

Is there an easy way to calculate values across an entire group?

e.g. Can I get a value that shows the highest CPU usage for all systems in a host group?

Cheers,

Read those FINE manuals ;-)

Great!

I've tried creating an item with the following key

grpmin["Windows servers", "vm.memory.size[free]", last, 0]

but it keeps just becoming not supported according to the zabbix_server.log.

I created it in a template, and applied the template to a couple of hosts - one within the Windows servers group and one outside it (the Zabbix server)

How should I be using it?

Cheers,

Only active items on enabled hosts are included in the calculations.

The Windows servers host group has >100 servers active with both items monitored.

I change it to run against on of our smaller groups with just 3 hosts in it, all active and monitoring this item, but it still becomes not supported.

Any other ideas?

I'll have a look at turning up the level of logging on the zabbix_server.

I have it working now - I'd forgotten to change the item type to Zabbix Aggregate.
