    Hello Krishnaprasad,<br>
    <br>
    I recently updated and published the documentation of Kwapi:<br>
    <a class="moz-txt-link-freetext" href="https://kwapi.readthedocs.org/">https://kwapi.readthedocs.org/</a><br>
    <br>
    And I created a project home page here:<br>
    <a class="moz-txt-link-freetext" href="https://launchpad.net/kwapi">https://launchpad.net/kwapi</a><br>
    <br>
    As Simon said, Kwapi aims at monitoring physical machines, with
    wattmeters.<br>
    It is not aware of the VMs running on physical hosts, neither of
    their resource usage (% CPU).<br>
    Kwapi doesn't depend of OpenStack components, except the API plugin
    which is able to check Keystone tokens.<br>
    <br>
    However, your idea is really interesting and I will be happy if this
    feature could be implemented in Kwapi.<br>
    <br>
    So I suggest to create a new plugin (or adapt the API plugin).<br>
    Every x seconds, for each known host, it will get the resource usage
    of each running VM.<br>
    The probes names will have to be configured properly, so that the
    probes names = the Nova hostnames.<br>
    Each measurement will be split into multiple measurements, one for
    each VM.<br>
    <br>
    Please feel free to create a blueprint here:<br>

          I forwarded your message to Francois who's maintaining the

          Francois will confirm or infirm but as I understand, there has
          been no short-term plan for kwapi to monitor the energy
