Thanks for your quick answer !
I'm sorry to ask this question but where could I find the vmstat-larrd.pl file ?
Sincerly,

Thomas

Oh,
my mistake. You are using hobbit and I use the "old BB".
Hobbit has a "build in" LA/RRD-engine and because of that you don't have the vmstat-larrd.pl script.
Sorry but I'm not able to give you an advice on how to handle this...
