I've created a Graph Template on Cacti which sums Memory Free, Memory Buffers and Cache Memory from a graph into a new one.
To do so, I've used a CDEF function with custom string:
My graph template:
When I want to use this template, I'll have to add a new graph using Graph Management and to select the corresponding value for a, b, and c as so:
Is there any way to use my graph template on the fly for my hosts without having to select for each graph:
For server A, Memory Buffers is server A - mem_buffers, Memory, for server B etc...
When I go to Device > hosts > Associated Graph Templates > Add Graph Template, Cacti doesn't allow me to fill Supplemental Graph Template Data: I get the following error when submitting the graph's creation:
"Notice: Undefined index: local_data_id in /usr/local/web/htdocs/cacti-0.8.8a/graphs_new.php on line 206

Thank you in advance for your help,
