<P class=MsoNormal><FONT face=Arial color=navy size=2><SPAN
style="FONT-SIZE: 10pt; COLOR: navy; FONT-FAMILY: Arial">If you can see the date
and time on the .rrd files changing regularly, then this confirms that MRTG is
running, and updating the RRD files. Therefore, the problem is that nulls
are being stored.<o:p></o:p></SPAN></FONT></P>

<P class=MsoNormal><FONT face=Arial color=navy size=2><SPAN
style="FONT-SIZE: 10pt; COLOR: navy; FONT-FAMILY: Arial">1) The data really is
null. Maybe the device being monitored is down or unreachable, or your
community string is wrong. Check the output of MRTG when run interactively
to look for error messages.<o:p></o:p></SPAN></FONT></P>
<P class=MsoNormal><FONT face=Arial color=navy size=2><SPAN
style="FONT-SIZE: 10pt; COLOR: navy; FONT-FAMILY: Arial">2) The data is out of
bounds. If you have MaxBytes or AbsMax set to a too-low value, then
retrieved data may be seen as too large and so a null is
stored.<o:p></o:p></SPAN></FONT></P>
<P class=MsoNormal><FONT face=Arial color=navy size=2><SPAN
style="FONT-SIZE: 10pt; COLOR: navy; FONT-FAMILY: Arial">3) When you do an
rrdtool dump, look at the beginning for the PDP Status. See what ‘value’
and ‘unknown_sec’ are, these show the last values
retrieved.<o:p></o:p></SPAN></FONT></P>
