Some Smokeping doubts

Hi all,

I’m using Smokeping ( and I have some
doubs that maybe you can answer:

- Why Smokeping needs to be connected to internet even when I have
only one Target to a host in my LAN ?

- What is exactly the Standard deviation calculated at the bottom
right of the graphs? Can it be interpreted as Jitter? Or is there another
way to know the jitter?

- Why sometimes when I add a new host, for the first minute I get
a list of errors saying that the RDD file doesn’t exist? This happens
commonly? Is there any way to solve this problem?

Many thanks,
