NFSen Integration

Help
1

Hi guys,

Just want to know if there is someone who successfully integrates NFSen to LibreNMS?
What are the requirements? Does it have to be in separate server? Or could run in a single server?

Most especially, a clear instruction of the configuration and setup of NFSen and LibreNMS.

Advance thank you for those who are willing to share their knowledge.

HI @rysantiago

What you get with the NFSen integration is only the Packets/Flows/Traffic graphs.

Said that, whats your issue? If you follow the docs it should work.

I did it as a separate VM, and then mounted a folder where NFSen stores all the data on my LibreNMS box.

Personally - After setting it up, I didn’t find it to be all that worth it.

As @TheGreatDoc alludes to, there’s not a huge deal of info that currently shows with it in LibreNMS.

See below as an example:

I’m not sure if it was necessarily required, but because I was also using Sflow rather than netflow, I compiled NFDump from source, which was actually quite frustrating to do, as the docs for it didn’t document all the required dependencies.

This is what I did to install NFDump:

apt update
apt-get install apt-utils dialog apache2 php7.2  pkg-config rrdtool librrd-dev
apt install libtool autoconf autogen
apt install bison byacc  flex -y
apt-get install libbz2-dev
cd /usr/src
wget https://github.com/phaag/nfdump/archive/v1.6.17.zip
unzip v1.6.17.zip
cd nfdump-1.6.17
mkdir m4
./autogen.sh
./configure --enable-nfprofile --enable-sflow
make && make install
# Without below this, later nfsen installation says:
# /usr/local/bin/nfdump: error while loading shared libraries: libnfdump-1.6.17.so: cannot open shared object file: No such file or directory
ldconfig

LibreNMS config:

$config['nfsen_enable'] = 1;
#$config['nfsen_split_char']   = '_';
$config['nfsen_rrds'][]   = '/data/nfsen/profiles-stat/live/';
$config['nfsen_rrds'][] = '/data/nfsen/profiles-stat';
$config['nfsen_suffix']   = "xxxx.lc";

So I have NFsen server mounted to /data/nfsen

Cumulus Linux have a good section and link to an article on setting up nfsen:

If I was to do it again, I would rather have spent the time trying to get this working:

Thanks,

Matt

Thanks @mattie47 this is very helpful!!

Now, I know what will be the result. Our objectives is to monitor the usage of each users using LibreNMS. But as per the screenshots you’ve provided I think this add-on does not meet our requirement.

But still, I would like to express my appreciation to you guys for being an active member of the community. Keep up the good work and have a good day!!
