Module monitors frontend and backend metrics such as bytes in, bytes out, sessions current, sessions in queue current.
And health metrics such as backend servers status (server check should be used).

    * Kilobytes out/s
    * Sessions current
    * Sessions in queue current

  2. Backend family charts
    * Kilobytes in/s
    * Kilobytes out/s
    * Sessions current
    * Sessions in queue current

  3. Health chart
