Nagios Support Forum

Hello,
We are currently running a demo of Nagios XI and I recently added a few Cisco Routers that have 10Gbps interfaces. The bandwidth statistics are wrong, and I'm aware of the fact that the SNMP reads that are done on those interfaces need to be 64 bit counters in order to reflect accurate statistics. My question is "how is this done in Nagios XI ?" I found a plugin called check_iftraffic42.pl that seems to do this according to it's documentation, but after installing the plugin I'm a little unclear whether this will solve the problem or not and how to actually use the plugin. I'm sure some of this is in the manual or in a 'how to' somewhere, but I just want to make sure I'm going in the right direction before I spend a lot of time on it because I was also wondering if there is a built-in way to deal with this issue, and whether any additional plugins are even necessary.

Thank you,
Ian.

Did you use this wizard?

http://exchange.nagios.org/directory/Ad ... rd/details

Yes, I believe that I did. I used that wizard to install it, and selected 'descriptions' to tag the interfaces, I may have set the wrong default bandwidth, if that makes a difference. I tried to rediscover the router, but it won't let me delete it, which I guess may be another problem.

What SNMP version did you use?

I believe 2c introduces 64 bit counters.

When I discovered the node, I used version 2, selected from the dropdown of the switch and router wizard. I just removed the node, and rediscovered it, with the same result, although the .rrd files seem to still be there, as I still have a history of interface stats, despite having just rediscovered the node. Maybe the new stats will incorporate the 64 bit counters....time will tell. I will update later.

thanks for keeping us updated

Hello,
The interface stats are still not reporting correctly. What information can I supply to help nail down where the problem is?

Thank you,
Ian.

Is this just one switch?

Can you PM me your /etc/mrtg/mrtg.cfg

Thanks
