[rrd-users] RRD generate lines step sized on future??

[Daniel Hilst]

When I ran "rrdtool fetch somefile.rrd AVERAGE -s -15m"

The last line is aways STEPSIZE on future and nan.. so if my step is 2 
minutes, and the output of fetch is

1346781480: nan
1346781600: nan
1346781720: nan
1346781840: 1.0000000000e+00
1346781960: 1.0000000000e+00
1346782080: nan


^ This epoch is 2 minutes on future.

I'm facing problems with collectd and nagios integration when I change 
step from 10 to something greater than 20 secs.. I think that this 
"future step" is causing collectd-nagios to misbehave. Is there a way to 
configure this rrd's behavior??

I'm thinking here, why would I have an step on future, if it do not 
happen yet... is a kind of optimization??


Thanks in advance!
Hilst
