    It sure is, we as well abandoned the MongoDB backend for Gnocchi
    which works pretty well.<br>
    <br>
    Would be a shame if a migration back would be required, maybe we can
    get a discussion going on a more<br>
    long-term solution as was discussed when talking about the future of
    Ceilometer.<br>
    <br>
    Supporting Gnocchi or moving to another open source project as a
    storage backend that is stable and maintained.<br>
    There were (and still is? Though unofficial out-of-tree) storage
    backends for Ceilometer that publishes to InfluxDB.<br>
    <br>
    I were never able to follow-up on the meetings (I probably missed a
    lot of it) regarding the Ceilometer roadmap [1].<br>
