Graphite integration
Example screen:
We could store pps/bps/flow number for top 7 (could be configured) host in incoming and outgoung directions. In addition to this we export total pps/bps/flow number which flow over FastNetMon.
Configuration from FastNetMon side is very simple, please put following fields to /etc/fastnetmon.conf:
graphite = on graphite_host = 127.0.0.1 graphite_port = 2003 graphite_prefix = fastnetmon
Install Graphite on Debian or Ubuntu
First of all, please install all packages:
sudo apt-get install -y python-whisper graphite-carbon
Whisper – it’s database for data. Graphite – service for storing and retrieving data from database.
Install web frontend:
sudo apt-get install -y graphite-web
Create database, specify login/password and email here:
sudo graphite-manage syncdb
Specify your timezone in file /etc/graphite/local_settings.py on line TIME_ZONE.
Change owner:
sudo chown _graphite:_graphite /var/lib/graphite/graphite.db
Run it with apache:
sudo apt-get install -y libapache2-mod-wsgi apache2-mpm-prefork sudo cp /usr/share/graphite-web/apache2-graphite.conf /etc/apache2/sites-available/graphite-web.conf sudo a2dissite 000-default.conf sudo a2ensite graphite-web sudo a2enmod wsgi
Enable load on startup:
sudo systemctl enable apache2.service sudo systemctl restart apache2.service
Open site: http://ip.ad.dr.es
Put test data to Graphite:
echo "test.bash.stats 42 `date +%s`" | nc -q0 127.0.0.1 2003
If you have issues with Carbon like this:
/etc/init.d/carbon-cache start
* Starting Graphite backend daemon carbon-cache Traceback (most recent call last):
File "/usr/bin/carbon-cache", line 32, in <module>
run_twistd_plugin(__file__)

raise UsageError("Unknown command: %s" % sub)

Some useful graphics for Graphite.
Total load:
fastnetmon.incoming.pps fastnetmon.outgoing.pps fastnetmon.incoming.mbps fastnetmon.outgoing.mbps
Top talkers:
highestMax(fastnetmon.hosts.*.outgoing.average.pps, 10) highestMax(fastnetmon.hosts.*.outgoing.average.mbps, 10) highestMax(fastnetmon.hosts.*.incoming.average.pps, 10) highestMax(fastnetmon.hosts.*.incoming.average.mbps, 10)
Also I recommend to configure Graphite this way.
For big networks please enlarge number of created file in /etc/carbon/carbon.conf:
MAX_CREATES_PER_MINUTE = 5000
And if you want to store data every 5 seconds for 1 month please do following before starting collection to Graphite in file /etc/carbon/storage-schemas.conf:
[default_5sec_for_1month] pattern = .* retentions = 5s:31d
