[rrd-users] Start time with rrdtool create

[Glenn MacGregor]

Let me add to my last post.

rrdtool create test.rrd --step 300 --start 1182758400
DS:sr:GAUGE:600:U:U RRA:AVERAGE:0.5:1:1200
 
rrdtool dump test.rrd > test.xml

You will notice the last entry in the only rra is the start time. This
is not what I would expect.

Thanks

 Glenn

Gelnn,

use rrdtool info or rrdtool dump to see what is in the rrd file ...
rrdxport is for reports ...
