32-bit counters, which makes the plugin unreliable and unsuitable for
most 100-Mb/s (or faster) interfaces, where traffic is expected to
exceed 50 Mb/s over a 5 minute period. This means that this plugin is
unsuitable for most 32-bit production environments. To avoid this
problem, use the ip_ plugin instead. There should be no problems on
64-bit systems running 64-bit kernels.<br></blockquote><div><br></div><div>obviously this is cacti, but i'd imagine that the plugins aren't different in how they measure, and therefore this problem.</div><div><br>

<div>Hi Daniel,<br>
We had a problem where cacti couldn't graph speeds of over
100mbit in graphs.<br>
We found you have to set the data query data type to the
64-bit counter type when creating the graph.<br>
Hope this helps.<br>

<div>You might find it is snmpd on the host if it is Linux.</div>
<div> </div>
<div>The SNMP daemon doesn't have permissions to get the

<div>If you add:</div>
<div>interface eth0 6 1000000000</div>

<div>Hey Noggers</div>
<div> </div>
<div>We use cacti for our bandwidth monitoring</div>
<div> </div>
<div>Recently I have noticed that none of my servers
graphs are showing the transit peaking over 100mbit
which is untrue as all servers are on 1GBit ports, I
have verified this numerous times, but yet cacti
won't graph above 100mbit</div>
<div> </div>
<div>Can somebody please tell me how I can fix cacti
to graph up to 1gbit?</div>

<div>Appreciate the assistance in advance</div>
