Hello,

I've just installed a new smokeping 2.4.2 instance and have several
slaves set all using the fping probe to ping each other. I have verified
that the RRDs are updating properly by looking at the RRDs and putting
the smokeping daemon in debug mode to verify the receipt of data on the
master.

When I view the smokeping web frontend all graphs display NaN for all
data points. Smokeping has been running for a couple hours now and
updating the RRDs for this time.

I have a few other 2.3.x smokeping installations that are working
properly so I don't believe I have missed any necessary steps in the set
up process.

Sample Debug Output:

To me it seems that the smokeping.cgi script isn't generating the graphs
properly. Apache is being run as the same user that owns the RRDs. This
user has access to all smokeping components.

Any idea what I might be missing?
