[rrd-users] Re: Newbie a bit confused and needs help

[Rick Blundell]

Check out the --start and --end command line arguments you can feed to
the rrdtool command.  The unit is seconds, and positive numbers are in
relation to epoch.  Negative numbers are relative to the current time,
which I find easier to use.

Last Week:
--start=-604800 \
--end=-300 \

Last Month:
--start=-2592000 \
--end=-300 \

Last Hour:
--start=-3594.24 \
--end=-300 \

And so on...


Hope this helps!
