Actually I see only my two lan cards.

When I try to mrtg the conf file (/usr/local/mrtg-2/bin/mrtg mrtgnew.cfg) I
see this error:

root at bizio:/home/rizla/net-snmp-5.0.8# /usr/local/mrtg-2/bin/mrtg
Unknown SNMP var dskPercent.1
 at /usr/local/mrtg-2/bin/mrtg line 1678
Unknown SNMP var dskPercent.2

WARNING: Skipping Update of localhost.disk, outlast is not defined

I've added this line (as Grek suggest) into mrtgnew.cfg:

Target[localhost.disk]:dskPercent.1&dskPercent.2:community at localhost
RouterUptime[localhost.disk]: community at localhost
MaxBytes[localhost.disk]: 100
Title[localhost.disk]: Disk Usage
PageTop[localhost.disk]: <H1>Disk / and /home usage %</H1>
Options[localhost.disk]: growright, gauge, nopercent
ShortLegend[localhost.disk]: %
YLegend[localhost.disk]: Disk Utilization
Legend1[localhost.disk]: Root disk
Legend2[localhost.disk]: /home disk
LegendI[localhost.disk]: Root disk
LegendO[localhost.disk]: /home disk

How to see the graphics of swap and disk space ?

Thanks again
