问题
I have setup a mrtg setup with rrdtool. Now I'm planning to get incoming outgoing usage data from these RRD files and failing to find a correct way to do it. Can anyone show we how to get those usage data from rrd files. Then I can maintain a db to keep those usage data and calculate the cost etc.
Thank you!
回答1:
you can use rrdtool graph ... PRINT:xxx
or rather rrdtool xport ...
to get data out of the rrd file. If you want to get to the actual data, use rrdtool fetch
.
you can find tons of additional info on http://rrdtool.org
