Hello,

I am trying to monitor the ATM cells both incoming and outgoing on a 34m link
between Nokia DSLAM nodes. My problem is the log only has values for the last
epoc time MRTG was run. All other log values are zero. see the examples below
of  the log file after MRTG has been run a few seconds apart on the config 
file:

First Run
1031801467 870313 199079
1031801467 0 0 0 0
1031799231 0 0 0 0
1031799000 0 0 0 0
1031798700 0 0 0 0
1031798400 0 0 0 0
1031798100 0 0 0 0

Second Run
1031801536 870313 199079
1031801536 0 0 0 0
1031801467 0 0 0 0
1031801400 0 0 0 0
1031801100 0 0 0 0
1031800800 0 0 0 0


The MIB OID is guage and only takes a reading every 15 minutes and is known
as Follows:
atmInterval15MinRxCellCnt: .1.3.6.1.4.1.1713.1.1.1.9.2.1.1.2.instance
atmInterval15MinTxCellCnt: .1.3.6.1.4.1.1713.1.1.1.9.2.1.1.3.instance



Following is a sample of my config file:

Target[172.20.20.159.cells]: 
1.3.6.1.4.1.1713.1.1.1.9.2.1.1.3.91.2&1.3.6.1.4.1.1713.1.1.1.9.2.1.1.2.91.2:public at 172.20.20.159
MaxBytes[172.20.20.159.cells]: 32000
Title[172.20.20.159.cells]: sydmcs01nD50e Dalley trunk ATM Cell Count
YLegend[172.20.20.159.cells]: Dalley Trunk ATM Cell Count
LegendO[172.20.20.159.cells]: Dalley Trunk ATM Cells Transmitted:
LegendI[172.20.20.159.cells]: Dalley ATM Cells Received:
Options[172.20.20.159.cells]: Growright, Gauge, Integer
PageTop[172.20.20.159.cells]: <H1>sydmcs01nD50e Dalley Trunk ATM Cell 
Count</H1>
   <TABLE>
     <TR><TD>System:</TD>     <TD>sydmcs01nD50e</TD></TR>
     <TR><TD>Description:</TD><TD>Dalley Trunk ATM Cell Count </TD></TR>
   </TABLE>

Please note I have also tried inserting a dot (.) in front of the OID to no 
avail.
I have also used the following options  Growright, Absolute, Gauge, Integer.

An snmpwalk gets the following results:
root# snmpwalk 172.20.20.159 public .1.3.6.1.4.1.1713.1.1.1.9.2.1.1.2.91.2
enterprises.1713.1.1.1.9.2.1.1.2.91.2 = Gauge32: 326458
root# snmpwalk 172.20.20.159 public .1.3.6.1.4.1.1713.1.1.1.9.2.1.1.3.91.2
enterprises.1713.1.1.1.9.2.1.1.3.91.2 = Gauge32: 611012
root#

The format in the above config file works ok for graphing a Cisco router 
memory usage.

Can anyone help?

Thanks Paul
