filename with name Variable instead of host variable in graphite

[stonby]

Does anyone know how to get the Name of a Device instead of the IP passed as Filename to graphite?
I would like to use the name Filed instead of the Host Field, as the Tree would be better readable.

Config:

probes:
  - name: blub
    type: std_fping
    output:
      - graphite_loss

    groups:
      - name: Group1
        hosts:
          - host: 10.11.12.13
            name: Device1

plugins:
  - name: graphite_loss
    type: graphite

    filename: "{source}-{host}-{field}"
    graphite_host: "127.0.0.1"
    protocol: "http"
    prefix: vaping
    field: loss

When Changing the Line of filename to name

    filename: "{source}-{name}-{field}"

Vaping crashes with this Stacktrace:

vaping.daemon stopping graphite_loss daemon.py:256
vaping.daemon stopping blub daemon.py:256
