Grafana will provide a visual view for the sites, InfluxDB is the data box, and collectd/telegraf is the agent on the server. Here we go.

Install Grafana:

# Download deb from https://github.com/fg2it/grafana-on-raspberry
root@raspberrypi:~# rpm -i grafana.deb
root@raspberrypi:~# service grafana-server start

Install InfluxDB:
Download from https://portal.influxdata.com/downloads

root@raspberrypi:~# tar xf influxdb-1.2.0_linux_armhf.tar.gz
root@raspberrypi:~# cp -a influxdb-1.2.0-1/* /

vim /etc/influxdb/influxdb.ini:

[admin]
enabled=true

[http]
enabled=true

[collectd]
enabled=true
bind-address=":25826"
database="collectd"

Then run “influxdb &” and check it out in http://localhost:8083, add db named “collectd”.

Install Collectd:

root@raspberrypi:~# apt-get install collectd

In /etc/collectd/collectd.conf, find :

<Plugin network>
    <Server "localhost" "25826"></Server>
</Plugin>

Then restart collectd service.

Now you can visit http://localhost:3000 to add InfluxDB source and add panel.
