[smokeping-users] empty graphs

I scanned your earlier messages, but didn't do more than a quick scan - thus it's possible I've missed something.

I'm assuming you're running a current debian version and are using a debian packaged smokeping. [2.6.11 *is* pretty old (late 2014), but I don't think that's the source of your problem - but it makes me wonder about how current your debian install is. Which, is again, unlikely to be the source of your issue - but it's something to consider for the longer term - security and OS updates...]

So, nothing changed that was a proximal cause of the problem? Like a debian upgrade? It just spontaneously broke?

GG> The rrd files seem to be getting updated properly, 

How sure are you that the RRD's are updated? This is the first place I'd start looking.
Running in debug mode often helps.

smokeping --debug

Watch the output.

Enpty graphs is a common symptom of RRD's not getting the data - and that's usually a permissions issue. But the PNG's will get produced.

See the FAQ:

GG> I have had a smokeping running for years(!) on a small local
GG> Linux system - but something broke.

GG> I started getting a BigLoss, and to fix it I had to delete a
GG> target in /etc/.../Targets. (It was down for a long time before I finally fixed it.)

GG> Then it seems to run again (after restart), but I get no graphs;
GG> but instead empty boxes for each target where a graph should be. I
GG> did a remove and re-install, no effect.

GG> Seems like the uninstall does not remove everything since it
GG> still had all of my Targets on the new startup.

GG> I am not sure how to debug or remedy this, any hints or ideas?
