I do rrdtool dump and examine the output, but it should be the same,
so this is ok.

There is an option of how many unknown values to be tolerated in the
rrd. I think you should make the rrd file keep more relaxed. Maybe.
But then my "knowledge" is at its end... Maybe try with a rrd with a
higher precision than your measurements? Try with 300 secs accuracy
instead of 900, take a look at it. If it is no better than 900, delete
it. I'm a "try and error" man...

Thats fine, should work. Looks perfect.
