Hi Matt,

For task “OVS collectd interface/port state monitoring”, which parts should be monitored? For example: Bridge, Port.

https://storyboard.openstack.org/#!/story/2002948

https://bugs.launchpad.net/starlingx/+bug/1834512

Bridge "br-phy1"

        Port "br-phy1"

            Interface "br-phy1"

                type: internal

        Port "eth1"

            Interface "eth1"

                type: dpdk

                options: {dpdk-devargs="0000:18:00.1", n_rxq="1"}

        Port "lldp8a3c28ca-7f"

            Interface "lldp8a3c28ca-7f"

                type: internal

The command “ovs-ofctl dump-ports-desc $ovs_bridge” can be used with collectd for both OVS and OVS-DPDK. The link status for interfaces can be detected as below:

For OVS:

After pull the cabel:
