I have nagiosgraph set up on nagios.   The plotting is working on services 
for local system, but not  on the remote systems' services.

Here is the nagiosgraph debug log for a service "biwofe_CPU".   All values 
are "nan" since yesterday.   I did many tries, at one time it showed only 
one data set plot.  no continuous data were generated and plotted.   I 
removed all files in rrd directory and restarted the nagios service. From 
the log I couldn't tell where could be the problem.   Spent one whole day 
and still couldn't move forward.    Appreciate if someone can help!
