          There are different types of Graphite compatible backends. Here you can specify the type you are using.
          If you are using <a href="https://github.com/grafana/metrictank" class="pointer" target="_blank">Metrictank</a>
          then select that here. This will enable Metrictank specific features like query processing meta data.

          Metrictank is a multi-tenant timeseries engine for Graphite and friends.
