Greetings, I have a topology where the opendaylight controller controls a bunch of switches. Now if load on one of the switches exceed. How does opendaylight controller comes to know about the load alert. Is there any functionality of controller which can check over load? Or do we need to write code for it? Thanks

The answer to the question depends on various factors. Ofcourse the most primary factor would be the support available 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.
