Sum of items

[volotoviu]

Hello, i have host group of four servers.
Templates with items where agent type ssh like (key ssh.run[Собака,{HOST.IP},22,<encoding>])
Result item would be number like (grep -c 'dog' /tmp/dog.log)
This Templates add on all hosts
Now i need sum result items from all hosts. How i can do it? Calculation agent work only inside host, dependent or aggrigate not working too.

Example what i want:
item name - cdog
host1:cdog=2
host2:cdog=1
host3:cdog=5
host4:cdog=1

reslt=9

Thanks

ty, i will try

[volotoviu]

I create new host, add him into host group AGG. In this group also host1-4.
create dependent item in templates.
Then try create aggregate func, got error

I think my problem with Host group, only aggragate host includes in this host group

its works,
1. need dependet items
2. only host who need aggregate add into host group
thanks all
