Well that's not necessarily wrong, it depends what you want to do with
the logging output.  I always prefer syslog (actually I use syslog-ng)
but it's just because that's what I'm familiar with.  OTOH if you told
smokeping to write to a log file that it doesn't have permission to
write to, then that might be a problem.  You might reasonably expect a
message somewhere telling you that it was a problem, but you'd be more
than a little foolish to bet money on it. :)

You mean that smokeping is actually updating the .rrd files now?!

Looks good.

Right.  There's no reason that the numeric user id on your machine should
be the same as that on mine for the smokeping user.  The simplest way to
look at that information is to list /etc/passwd.  Type

man 5 passwd

for more infomation about that file.
