+### Graphite integration
+
+Example screen: ![Graphite](docs/images/fastnetmon_graphite.png)
+
+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:
+```bash
+graphite = off
+graphite_host = 127.0.0.1
+graphite_port = 2003
+```
+
+### Install Graphite Debian 8 Jessie 
+
+First of all, please install all packages:
+```apt-get install python-whisper graphite-carbon```
+
+Whisper - it's database for data. Graphite - service for storing and retrieving data from database. 
+
+Install web frontend: ```apt-get install:  graphite-web```
+
+Create database, specify login/password and email here: ```graphite-manage syncdb```
+
+Change owner:
+```chown _graphite:_graphite /var/lib/graphite/graphite.db```
+
+Run it with apache:
+```bash
+apt-get install libapache2-mod-wsgi
+cp /usr/share/graphite-web/apache2-graphite.conf  /etc/apache2/sites-available/graphite-web.conf
+a2dissite 000-default.conf
+a2ensite graphite-web
+```
+
+Enable load on startup:
+```bash
+systemctl enable apache2.service
+systemctl restart apache2.service
+```
+
+Open site: 
+http://10.0.3.114
+
+Put test data to Graphite:
+```echo "test.bash.stats 42 `date +%s`" | nc 127.0.0.1 2003```
