The NaN issue..

[ct2k7]

Hi,

I'm facing the NaN issue on all graphs in my Cacti instance.

I've followed the NaN troubleshooting here: http://docs.cacti.net/manual:088:4_help ... #debugging to no avail.

My current log looks like so:

No errors or any warnings.

File ownership is set to the cactiuser.

Any ideas?

What happens when you try to manually perform the rrdtool updates, using the "cactiuser"?
