Using Calculated Items in Templates?

[netmon]

Dear all,

Is it possible to use Calculated Items in Templates? (Version 1.8.10)

I try to calculate free RAM in percent for two SNMP Items.

Used Memory: KEY_NAME_OF_OIDA
Avail Memory: KEY_NAME_OF_OIDB
Template Name: TEMPL_NAME

Formula:
last({TEMPL_NAME:KEY_OF_OIDA})/last({TEMPL_NAME:KEY_OF_OIDB})*100

Something seems to be wrong. I do not get a value with the above formula.
If I replace TEMPL_NAME with any NAME_OF_HOST (for which I build the template) it works.
Therefore it seems, that I cannot build Calculated Items through Templates.

Do I need to create this kind of Items PER HOST?!

Any Idea? :/

Hi,

I use calculated items in templates and they are working.

For example, this is what I use for "Used memory" :

last(vm.memory.size[total])-last(vm.memory.size[free])

I think that your syntax is wrong.
Could you try :

last(KEY_OF_OIDA)/last(KEY_OF_OIDB)*100

Hope this helps
JBo

Thank you JBo, you are right!

I use {TEMPL_NAME:KEY_OF_OIDA.last(0)} inside Graphs for my SNMP Items and thought this would be similar for Calculated Items. Wrong!

Simply using last(KEY_OF_OIDA) is fine... :-)

What can be Wrong...


last(vm.memory.size[total])-(last(vm.memory.size[free])+last(vm.memory.size[cached])

What can be Wrong...


last(vm.memory.size[total])-(last(vm.memory.size[free])+last(vm.memory.size[cached])

It worked !

last(vm.memory.size[total])-last(vm.memory.size[free])-last(vm.memory.size[cached])
