There is now more of a differentiation but there is still a lot of outbound traffic (which is at a greater rate that the inbound).

I think the check is monitoring the Management interface, it that the correct interface?

The check is configured to check this file

Code: Select all

/var/lib/mrtg/10.128.38.17_1.rrd
Which is mapped to this interface in the 10.128.23.17.cfg file

Code: Select all

SetEnv[10.128.38.17_1]: MRTG_INT_IP="10.128.38.17" MRTG_INT_DESCR="Management"
If you want to monitor the P1 interface, you need to edit that service check and change the following in $ARG1$
from

Code: Select all

10.128.38.17_1.rrd
to

Code: Select all

10.128.38.17_2.rrd
Save and apply the configuration.
Delete the xml and rrd files and see if that is what you want.

Our proxies are setup so that both traffic and management are on the same interface. This is 'normal', as far as Cisco is concerned. The way our networks are setup makes it difficult to separate management and traffic without a fairly major redesign.

What is the model of the Cisco device you are monitoring?

Since my last post, we have purchased Nagios XI and Network Analyser. A Cisco router has been configured to send NetFlow data to NA. It looks to be receiving data (disk usage has increased) but there is 'no data' to show. See attached. Any thoughts on this one? We are trying to achieve the same result (monitoring internet bandwidth/statistics) hence not creating an new thread here.

Thanks

If you are running version 9 of Netflow on your router, there could be a compatibility issue with the nfcap software running on the NA system.
In a shell on the NA system, run the following to recompile the software. Restart the sources and see if the data starts to capture for you.

Code: Select all

cd /tmp
wget http://sourceforge.net/projects/nfdump/files/stable/nfdump-1.6.13/nfdump-1.6.13.tar.gz/download
tar xzf download
cd /tmp/nfdump-1.6.13
./configure --prefix=/usr/local --enable-sflow --enable-nsel --enable-nfprofile --enable-nftrack
make
make install
If that doesn't work, can you post the settings from the Cisco Device?

Thanks. Yes, the router is using Netflow 9. I have run the commands, all completed successfully. This was about an hour ago - no data displayed yet.

Can you kindly provide the output of `show version` on the Cisco device?

Thanks
