Enable collectd input for influxdb

Edit /etc/influxdb/influxdb.conf collectd section part with the following:

[collectd]
  enabled = true
  bind-address = "localhost:25826"
  database = "collectd_db"
  typesdb = "/usr/share/collectd/types.db"

Have collectd sending data to influxdb

Edit /etc/collectd/collectd.conf to enable the Network plugin uncommenting the line

LoadPlugin network

and add the following network plugin config

<Plugin network>
        <Server "127.0.0.1" "25826">
        </Server>
</Plugin>

Restart influxdb and collectd:

sudo service influxdb restart
sudo service collectd restart

You should be able to find new series in collectd_db in influxdb admin page
