Hi all, I'm using OpenStack together with OpenDaylight to add a network awareness feature to the scheduler. I have 3 compute nodes (one of these is also the Openstack Controller) connected by a openvswitch controlled by OpenDaylight. What I would like to do is to write a filter to check if a link is up and then assign weight acconding to the available bw (I think I will collect this data by ODL and update an entry in a db). For each host I have a management interface (eth0) and an interface connected to the OVS switch to build the physical network (eth1). Have you got any suggestion to check the link status? I thought I can be inspired by the second script in this link http://stackoverflow.com/questions/17434079/python-check-to-see-if-host-is-connected-to-network to verify if the iface is up and then check the connectivity but It has to be run in the compute node and I don't know which IP address I could point at.
