Hi all, I'm suddenly getting a situation where rrdtool is picking up a low-resolution RRA instead of the one it used to use - I can't spot anything that has changed since it last worked, so I'm a little confused.
I'm using 1.0.41 - the same problem started in 1.0.40, and I've just upgraded because the entry 'fix borderline problem with rrd_fetch selecting the wrong rra under certain conditions' in the changelog seemed relevant! I'm using ganglia (http://ganglia.sourceforge.net/) to populate my RRDs, and have RRAs for hour/day/week/month/year/decade - see an example output from rrdtool info below. When plotting the monthly graphs, it should be using 240 datapoints; however, it's suddenly switched to just thirty - see sample output from rrdtool fetch below. And this is consistent across every graph I'm plotting. Ah - it gets more entertaining; it all works again now. And I definitely didn't change anything! The window of bad behaviour was maybe an hour (and I'm not normally looking at these graphs at this time of day/week!) Is it possible there's another bug along the lines of the one fixed in the changelog entry mentioned above? Is there anything I can do to help narrow down the problem? Thanks for any help!
