OpenStack Ceilometer SR-IOV Counters Support

Version 6

    The Mellanox Ceilometer SR-IOV module allows the OpenStack Ceilometer to collect measurements of SR-IOV counters.

    The Ceilometer libvirt inspector looks for the an interface (tap device) that is bound to the VM. The VM that is connected via SR-IOV doesn't have such interface therefore the libvirt inspector ignores it. The Mellanox Ceilometer SR-IOV module looks for VF PCI Device of the VM, then it acquires the counters from the driver and passes the counters to the OpenStack Ceilometer inspector.
