I have installed NagiosXI and try to configure a Network Switch / Router, all work fine, but i have one problem with graphs bandwidth...
My NagiosXI dont get the graphs from the Switch, i have to make any configuration?

./check_rrdtraf -f /var/lib/mrtg/10.254.194.3_10003.rrd -w 50,50 -c 80,80 -l b
But return a error:

Anyone can help-me?

Is there any data in your *.rrd file or it's an empty file? Can you run the same command against a different *.rrd file successfully?

Hello...

When i created the Switch/Router on Monitoring Wizard, all work fine, but, dont get the bandwidth usage from Switch...
Stay on 0Mb/s...

This is usually a permissions issue, what is the results of the following:

ll /var/lib/mrtg
ll /var/lib | grep mrtg
