[smokeping-users] empty graph for DNS.pm and TCPPing.pm

[Gabriel Filion]

hmm I don't see any indication that probing has any issue in your output.

I'm also not sure what you mean by "BEFORE fix" and "AFTER fix". what
fix do you mean? and does the fix make things work?

otherwise, to pursue things with very general and unguided advice: maybe
the probe is actually able to create rrd files, but then the files are
not accessible to the web interface? check out their permissions to be
sure they let your web interface access them.
