Was your disk full at some point, perchance?
When this happens rrdtool creates unusable empty rrd files which don't work.
The housekeeping script should remove these, or you can remove them yourself manually.

Hi,
I’ve been trying to get my graphs to work but I’m still getting NaN on ‘some’ of my them. I have a Cisco c891fw router and interfaces g2 and g3 graph fine but the other interfaces g0, g3, g4, g5 do not graph and I get a NaN but keep in mind that I do see their traffic transfer rates. I do not get a ‘draw error’, just a blank graph. I’m running the following:
Ubuntu 15.10
Observium CD 0.15.6.6430
NET-SNMP version: 5.7.3
RRDtool 1.4.3
I have updated to the latest RRDtool version 1.5.5 but then I get the draw errors. Is there anything you can provide to help.
Thanks,
ejw
