It shouldn't, unless your system is set up to use external DNS
resolvers, external mail servers for alerts, etc. With your system
disconnected from the Internet, try pinging/resolving/etc every host
name in your config files. I bet there's something in there that
won't work.<br>

Standard Deviation is the std.dev. of the collected RTT samples.
Obviously this is related to jitter in terms of describing "how much
from the mean do the samples go". However, "jitter" is an
imprecise and undefined term (there are several slightly different
ways of defining and measuring jitter, so you'd have to pick a
definition first), so what it means in relation to your specific
project is unanswerable.<br>

Smokeping doesn't poll every host every single second. Polling
goes into a queue, and is executed on a schedule defined internally
by Smokeping based on your "step" and "pings" settings. Until the
host's turn comes up in the queue and its polling is complete, the
RRD files aren't created. This is normal. Smokeping isn't, and is
not intended to be, a real-time, low-level monitoring solution.
It's intended to give you a sample-based/delayed view of what's been
going on historically.<br>
