Strange behavior in graphs on Cacti upgrade

[minmei]

Upgraded to 0.8.7d in March. No issues.

Upgraded to 0.8.7e a week ago. System is polling just fine. But I have a large gap (March to November) of data in each and every graph.

Looking at RRD's with a dump shows NANs in the affected area. But all graphs were fine a week ago, before the upgrade. With all data.

Any thoughts on what could be wrong?

TIA,

Chad

Please show us some screenshots of different timespans and the related rrdtool graph statement (get that by pressing the wrench icon) next to the graph

That's fine. And now an rrdtool info output of the related rrd file, please

Is it possible to post a gzipped rrdtool dump of that very rrd file to either my email address or by pm?
R.

[minmei]

Here's the gzip...

[gandalf]

Thanks, but please be patient. My todo stack is quite full
R.

[minmei]

Nevermind - sometimes one makes the most stupid mistakes and doesn't realize it until way too late.

Ended up with two sets of rrd files. Trying the python merge program to fix...

[gandalf]

Thanks for the follow-up. I indeed did not find time, yet. Great, that you found a way
