[mrtg] MRTG not graphing data

I am running MRTG to log error hits on our T1's here - or at least that
is what I am trying to do.


The log file shows the most recent SNMP get value on the top line, but
(other than the timestamps), the other lines are all showing zero's.


Relevant snippet from the cfg file:


Target[plym-8xds1_1]: ifInErrors.1&ifOutErrors.1:altaris at plym-8xds1

SetEnv[plym-8xds1_1]: MRTG_INT_IP="" MRTG_INT_DESCR="T1 1/1 Errors"

MaxBytes[plym-8xds1_1]: 100

Title[plym-8xds1_1]: Plymouth 8xds1 line 1 error counts

PageTop[plym-8xds1_1]: <H1>plym-8xds1 error counts</H1>


   <TR><TD>System:</TD>     <TD>plym-8xds1</TD></TR>

   <TR><TD>Maintainer:</TD> <TD>Ron Gage</TD></TR>

   <TR><TD>Description:</TD><TD>T1 1/1  </TD></TR>

   <TR><TD>ifType:</TD>     <TD>ppp (23)</TD></TR>

   <TR><TD>ifName:</TD>     <TD>t1 1/1</TD></TR>

   <TR><TD>Max Speed:</TD>  <TD>10 errors</TD></TR>



I can do an SNMPGET and/or SNMPWALK from the same server and can see the
values there.


The graphs being generated from MRTG show absolutely no data whatsoever
(flatline), even though separate monitoring is showing some of these
counters increasing on occasion.
