[ONOS-3203] End-to-end demo of Fault Management via SNMP.
This adds SNMP device-discovery, and a Fault Management app which makes alarms available to users via REST/GUI/CLI interfaces.
There is still code cleanup that could be done, but aim of this commit is an end-to-end proof of concept.
To demonstrate :
1) /opt/onos/bin/onos-service
onos> app activate org.onosproject.snmp
onos> app activate org.onosproject.faultmanagement
2) SNMP devices are seeded via config file. The default seed file contains connection details for devices (SNMP agents) available via internet e.g. demo.snmplabs.com
cp /opt/onos/apache-karaf-3.0.3/etc/samples/org.onosproject.provider.snmp.device.impl.SnmpDeviceProvider.cfg /opt/onos/apache-karaf-3.0.3/etc/
3) ONOS will poll these SNMP devices and store their alarms.
4) You can now manipulate the alarms via REST e.g. http://<onos>:8181/onos/v1/fm/alarms , via CLI via various "alarm-*” commands or in UI with an Alarms Overlay.
