[collectd] Collectd generated rrd shows nothing

   I have a basic installation of collected(5.0) on Ubuntu and have enabled
some plugins like load / cpu / log etc. I see collectd generating rrd
files. But when I try to query the rrd (via rrdtool fetch for the last 10
hours), I only get NaN results.

  I looked at the /var/log/collectd and did not see any errors.

 My config looks like:

#Hostname "localhost"
FQDNLookup true
BaseDir "/var/lib/collectd"
PluginDir "/usr/lib/collectd"
TypesDB "/usr/share/collectd/types.db"
Interval 300
#Timeout 2
#ReadThreads 5

#LoadPlugin logfile

# --------------------------
# active plugins start
# --------------------------
LoadPlugin syslog
<Plugin syslog>
LogLevel info
LoadPlugin cpu
LoadPlugin df
<Plugin df>
   Device "/dev/xvda1"
   MountPoint "/"
   FSType "ext4"
   IgnoreSelected false
   ReportByDevice false
   ReportReserved false
   ReportInodes false
LoadPlugin load
LoadPlugin memory
LoadPlugin rrdtool
<Plugin rrdtool>
   DataDir "/var/lib/collectd/rrd"
   CacheTimeout 120
   CacheFlush 900
   WritesPerSecond 30
   RandomTimeout 0

# The following settings are rather advanced
# and should usually not be touched:
   #StepSize 10
   #HeartBeat 20
   RRARows 1200
   RRATimespan 158112000
   XFF 0.1

How do I debug it?
