Module that combines modules?

[TVMike]

I want to combine parameters (modules?  I'm referring to the measured values that come from the modules) to produce a new value.  For illustrative purposes, let's say I want to add memfree and memused to get totalmem.  Then I could put memused and totalmem on a graph.  How can I do this?

Hello TVMike,

You can do it creating a new Custom graph. You can add modules to this graph, for example, with a stack area or stack line to get the totalmem in your example, with both values of memused and memfree.

Cheers.
