Hi Leo,

yes that's exactly what I thought of.
The idea was inspired by post coming up sometimes in the community about empty graphs. Mostly just a guessing about the reason gives the solution more or less quickly/slow. Maybe the real error messages leads quicker to the issue.

Regards,
Bernhard

Hi,

I didn't look at your patch in depth 'til now. But the integration of the errors from RRDtool looks good. Thanks for taking my suggestion in the discussion. I wasn't able to look at this since then, but it seems to be my solution I've tried some time ago on my system.
Could you test it with some errors of rrdgraph()?

Regards,
Bernhard
