I don't know, but I found your emails in my spam folder.

Look at the varnish-counters manual for better understanding.
SMA.*.c_bytes is the counter for all bytes allocated by your malloc

I'm not sure to understand your assumptions, but basically what you
give for storage (eg 6GB) is what you get for storage and storage
It doesn't include the rest of your Varnish memory footprint.

I don't know, shell scripting on top of varnishtop?
