The answer to the question depends on various factors. Ofcourse the most primary factor would be the support present in the south-bound protocol that lets the ODL controller talk to the said device. If the protocol carries the load information of a particular device, then Opendaylight controller will be able to use that information to perform some action on that.

For example, the OVSDB south-bound protocol supports this exact use-case and provides the OVS host's load information such as cpu, loadaverage, memory, filesystems etc.... in the OpenvSwitch schema. Please refer to the OpenvSwitch schema at http://openvswitch.org/ovs-vswitchd.conf.db.5.pdf & look for the Open_vSwitch Table column summary.

So, the answer to your question depends on the type of device and the protocol the device uses to interact with the Controller.
