Hi,
<div><br></div><div>I set up several devices on Obervium, no problem so far, except for the Traffic Graphs which remain empty.</div><div>For example : <a href="http://img4.hostingpics.net/pics/168961data.jpg">http://img4.hostingpics.net/pics/168961data.jpg</a></div>

<div><br></div><div>The RRD file exist, but the data always return 0.00</div><div><br></div><div>How can I debug that ? Is there an snmpwalk command to help understand the problem ?</div><div><br></div><div>Regards,</div>
