Hi Thomas,

That sounds like a good idea! On the API side, I would probably make it a

I agree with you, as more informations are needed, more columns will be
added.

I'm not sure if the meta table Setting is the best place to put this stats.
I can't see some I/O informations as database settings. IMHO, this could
'pollute' the table with not necessarily related informations. What you
think about in create a separated meta table database_statistics and put
all related informations in key-value format?

Fred
