[Starlingx-discuss] OVS collectd interface/port state monitoring

[Xu, Chenjie]

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:
controller-0:/home/sysadmin# ovs-ofctl dump-ports-desc br-phy0
OFPST_PORT_DESC reply (xid=0x2):

     speed: 0 Mbps now, 0 Mbps max
After plug in the cable:
controller-0:/home/sysadmin# ovs-ofctl dump-ports-desc br-phy0
