Template: using Items in Formula (adressing issue)

[Bernd Hohmann]

I have a Template "TPL Network Interface" with an Item "ITM Inbound bps" like

Name: ITM Inbound bps
Key: net.if.in[{$IF.NAME}]

I stuffed this item into a graph and everything looks fine.

Now I like to create another item which calculates the average for "ITM Inbound bps" over the last {$IF.AVERAGE} seconds to use it in a trigger and in a graph.

The item for this reads:

Host: TPL Network Interface
Name: ITM Average Inbound
Type: Calculated
Key: ifavgin
Formula: avg("TPL Network Interface:ITM Inbound bps",{$IF.AVERAGE})

But no data is returned from this item.

What is the correct adressing in the namespace of a template?

Use the item key in the formula, not the host:name syntax.

Use the item key in the formula, not the host:name syntax.

Doesnt work either

I created template with two items:

1) "Inbound" with key net.if.in[{$IF.NAME},bytes]
2) "Avg. Inbound" with formula avg("net.if.in[{$IF.NAME}]",{$IF.AVERAGE})


When I use this template on host "donald", the "Avg. Inbound" item complains with Cannot evaluate function [avg({$IF.AVERAGE})]: item [donald:net.if.in[{$IF.NAME}]] not found

I can put the ",bytes" into the formula so the key matches 100%, but this doesn't change the message much.

I guess the problem is, that the macro {$IF.NAME} isn't resolved here. What to do?
