[mrtg] Polling interval

Native mode MRTG can have 'Interval:1' to specify a 1-minute interval.  The
default for MRTG is 5minutes.


If you use RRDtool as your logformat, then you can have an interval as low
as 1sec with 'Interval: 00:01' (provided you have MRTG 2.16 or later) but of
course you have to complete your polling cycle in the time interval so don't
make it too short.


Note that, although you might be collecting the data more frequently, you
will need to find some way to display it yourself as the normal MRTG will
only generate 'daily','weekly','monthly','yearly' graphs, which corresponds
to about 1pixel per 5min.  The routers2 frontend for MRTG/RRD will also
generate 6hr graphs (for people with a 1min interval).  Smaller interval
swill require you to make your own arrangements.

Is it possible to change the polling interval lower then 15 minutes?
