Check the apache logs on the master and see if Apache is able to write the data from the slaves to the RRD's. [My guess is, it can't.]
Apache [or, more accurately, the user who Apache runs as] will have to have write access to the RRD's.
This can also be caused by Apparmour, or SELinux. [If the above doesn't fix it, then try running these in permissive mode.]

| Hi I use smokeping since a year with a master and a slave configuration, and everything was working fine until today... I decided to add a FPing6 probes on my config file, with 2 targets, but after few hours the slave's graphs are still empty (the ones from the master are doing great). I run smokeping from slave with debug, everything looks fine : [...] FPing6: Executing /usr/bin/fping6 -C 20 -q -B1 -r1 -i10 2001:bc8:328c:fff::42 ipv6.google.com FPing6: Got fping output: '2001:bc8:328c:fff::42 : 31.65 31.73 31.70 31.60 31.59 31.74 31.47 31.49 31.59 31.47 32.18 31.61 31.61 31.70 33.20 31.67 31.66 31.59 31.61 31.79' FPing6: Got fping output: 'ipv6.google.com : 11.30 11.40 11.29 11.38 11.08 11.19 11.99 11.34 11.26 11.33 11.95 11.37 11.24 11.31 11.28 11.23 11.40 11.39 11.29 11.18' [...] Sent data to Server.
